| jaypipes | bhagyashris: that's what the response will look like. | 13:16 |
| jaypipes | bhagyashris: you can get the resource provider UUIDs by grabbing response.get('allocations').keys() | 13:16 |
| bhagyashris | jaypipes: yes | 13:16 |

| bhagyashris | jaypipes: thanks, I have two doubt can you please guide me | 13:20 |
| bhagyashris | jaypipes: is it possible to assign resources from different resources providers for a given instance? | 13:20 |
| jaypipes | bhagyashris: yes. | 13:21 |
| jaypipes | bhagyashris: see above link for an example. | 13:21 |
| bhagyashris | jaypipes: As per my finding if i used the custom resource classes to create the inventory using the resource provider then it's possible but if i used the existing resource classes then it's not possible | 13:22 |
| bhagyashris | jaypipes: am i correct? | 13:22 |
| bhagyashris | jaypipes: ohh ok. | 13:22 |
| jaypipes | bhagyashris: custom vs. standard resource classes don't matter when creating inventory against multiple providers. | 13:25 |
| *** lpetrut_ has joined #openstack-nova | 13:27 | |
| bhagyashris | jaypipes: ok. | 13:27 |
| bhagyashris | jaypipes: how a aggregate is selected in placement service? | 13:28 |
| jaypipes | bhagyashris: just remember that when you call PUT /resource_providers/{rp_uuid}/inventory, that you are *replacing* the inventory of the resource provider each time you call that. | 13:28 |
| jaypipes | bhagyashris: aggregates are not selected. only resource providers are selected. aggregates allow relationships between resource providers, for example, to denote a grouping of like providers. | 13:29 |
| bhagyashris | jaypipes: for example, I have host-aggregate-1 and host-aggregate-2, and when a new request comes to boot an instance, then how the placement api decides in which host aggregate this new vm should be created | 13:29 |
| *** burt has joined #openstack-nova | 13:29 | |
| bhagyashris | jaypipes: ok. | 13:29 |
| *** lpetrut has quit IRC | 13:29 | |
| jaypipes | bhagyashris: that's not how things work :) instances don't get created "in an aggregate". Instead, instances get created on a compute host. That compute host may be associated with one or more aggregates. | 13:30 |
| jaypipes | bhagyashris: perhaps you're confusing availability zone with host aggregate? | 13:30 |
| bhagyashris | jaypipes: yes. | 13:31 |
| *** shaohe_feng has quit IRC | 13:33 | |
| jaypipes | bhagyashris: availability zone is an attribute (metadata key/value pair) against a Nova host aggregate. All compute hosts in the host aggregate belong to the availability zone that the host aggregate is marked with. That said, the placement API does not have anything to do with the availability zone. The Nova host aggregate and the placement aggregate are different things. For example, a Nova host aggregate actually refers to the nova-compute | 13:33 |
| jaypipes | service daemon, not the provider of resources. This is why, for example, Ironic baremetal nodes cannot individually be assigned to a Nova host aggregate. But Ironic baremetal nodes *can* be associated individually with a placement aggregate. | 13:33 |
| *** shaohe_feng has joined #openstack-nova | 13:33 | |
| jaypipes | bhagyashris: it's all ludicrously confusing, I know :( | 13:34 |

| jaypipes | efried: placement aggregates are groupings of resource providers, nothing more. Placement aggregates do not have traits associated with them. Placement aggregates are not "in an availability zone" or anything like that. Nova host aggregates are groupings of nova-compute service daemons (NOT the compute hosts that actually provide the resources). Nova host aggregates have metadata key/value pairs associated with them. Nova host aggregates are | 13:49 |
| jaypipes | an entity in any of themselves, whereas placement aggregates are nothing more than a UUID that provides a grouping to resource providers. | 13:49 |
| jaypipes | bhagyashris: ^ you too. :) | 13:49 |
| *** marst has joined #openstack-nova | 13:50 | |
| efried | jaypipes What are placement aggregates useful/used for? | 13:50 |
| jaypipes | efried: associating a resource provider to another. | 13:50 |
| jaypipes | efried: that's it. nothing more. | 13:50 |
| efried | Associating for programmatic or human consumption? | 13:50 |
| jaypipes | efried: right now, mostly programmatic. | 13:51 |
| jaypipes | efried: it's currently how we handle shared resources. | 13:51 |
| efried | So placement aggregates can overlap. | 13:51 |
| efried | I seem to recall asking this very question in Boston :) | 13:52 |
| efried | And the answer was yes | 13:52 |
| stephenfin | mriedem: Could you take another look at this this week? https://review.openstack.org/#/c/412356/ | 13:52 |
| edleafe | efried: placement can't select based on nova host agg | 13:52 |
| jaypipes | efried: in the future, I envision aggregates being associated to each other via a distance attribute. In other words, agg A and agg B are distance 1 apart. agg X and agg A are distance 4 apart, etc. | 13:52 |
| edleafe | efried: that's done in the scheduler filters | 13:52 |
| jaypipes | efried: this will provide us a way to model affinity and anti-affinity concerns in placement. | 13:52 |
| jaypipes | efried: yep, aggregates (either placement or Nova host aggregate) can overlap. | 13:53 |
| efried | jaypipes So it also makes sense that a nested resource provider will be implicitly aggregated with its parent. | 13:53 |
| *** tidwellr has joined #openstack-nova | 13:54 | |
| efried | ...and by extension, with its "siblings" and "cousins"... | 13:54 |
| jaypipes | efried: yes. I was planning on making a constraint that only root provider UUIDs could be associated with an aggregate. | 13:55 |

| dansmith | which makes it not really fit the online-data-migrations model | 14:44 |
| *** udesale has joined #openstack-nova | 14:44 | |
| dtantsur | mriedem: hey! when do you folks plan on finalizing your PTG schedule? I specifically wonder about the scheduling discussion, as we have a couple of topics there | 14:44 |
| mriedem | we can figure out the ironic nodes via the hypervisor_type on the compute_nodes table right? | 14:44 |
| mriedem | dtantsur: it's something i need to work on this week | 14:44 |
| dansmith | mriedem: we can yeah | 14:44 |
| mriedem | it's pretty open ended atm, except for thursday morning being cinder time | 14:44 |
| dtantsur | mriedem: we have a few topics depending on the scheduling discussion outcome to an extent. so I guess Wed would work better, probably afternoon. | 14:45 |
| *** suresh12 has quit IRC | 14:46 | |
| dtantsur | but it's up to you of course :) | 14:46 |
| dtantsur | vdrok: ^^ | 14:46 |
| dansmith | mriedem: so your preference would be to do it fully automatic like that? we kinda need to backport this if we're going to remove the migration from queens | 14:46 |
| mriedem | dansmith: so the problem with the offline data migrations command with this is we don't really have a marker i don't think | 14:46 |
| dtantsur | or just don't remove the migration from queens... | 14:46 |
| mriedem | since the extra specs are a json blob | 14:46 |
| mriedem | but i haven't thought it through fully | 14:46 |
| dansmith | mriedem: yup, hence my thinking that a one-shot command for a host would be good | 14:46 |
| dansmith | dtantsur: yeah, but we really want to stop allowing the old model too, which we *could* do separate from the migration piece, but... | 14:47 |
| mriedem | for all compute nodes where hypervisor_type == 'ironic'; find all instances where host/node in that list; do migrate instance extra spec | 14:47 |
| dansmith | the migration piece in compute also brings overhead | 14:47 |
| mriedem | dansmith: i wouldn't want to require a host, but it could be an option | 14:47 |

| dansmith | mriedem: well, for a dedicated command I was thinking make it specifically "run for instances on this host" so you're responsible for iterating hosts and therefore not running twice | 14:48 |
| *** hrw has joined #openstack-nova | 14:49 | |
| *** udesale has quit IRC | 14:49 | |
| *** coreywright has quit IRC | 14:50 | |
| mriedem | how do you know you've hit all hosts? | 14:50 |
| mriedem | and then someone will say, how do i get the list of hosts | 14:50 |
| dansmith | well, I'm thinking about tripleo where that's easy to determine | 14:51 |
| mriedem | running twice isn't a problem either right? it's just a no-op if already migrated | 14:51 |
| dansmith | sure, it's just super expensive | 14:51 |
| mriedem | i'm generally never thinking about tripleo | 14:51 |
| mriedem | :) | 14:51 |
| dansmith | heh | 14:51 |
| dtantsur | :D | 14:51 |
| mriedem | my preference would be, host is optional, so if someone thinks they know better and want to iterate hosts client side, fine | 14:51 |
| mriedem | otherwise we do it | 14:51 |
| dansmith | how about we make it expected, else there's an --all option, | 14:52 |
| dansmith | so it's clear that it's not just idempotent and zero impact? | 14:52 |
| dansmith | and to be clear, this is a dedicated command with specific behaviors, yes? | 14:52 |
| mriedem | it is idempotent except for the db read hit right? | 14:52 |
| dansmith | right, idempotent is the wrong word, because it is, I meant "resumable" or "zero impact if nothing to do" | 14:53 |
| dansmith | like, don't just run this on every puppet run | 14:53 |
| mriedem | how is tripleo going to determine that it's done all of the migrations? | 14:53 |
| mriedem | and can stop | 14:53 |
| dansmith | tripleo won't, | 14:54 |
| dtantsur | so, are you going to call into ironic in this command? | 14:54 |
| mriedem | dtantsur: no | 14:54 |
| dtantsur | sorry, I don't quite understand how you're going to know the resource class of the node | 14:54 |
| mriedem | dtantsur: this is just duplicating what we do in nova-compute startup | 14:54 |
| dansmith | it'll be a specific skip-level upgrades script | 14:54 |
| dtantsur | well, in nova compute we're using data from ironic | 14:54 |
| dansmith | dtantsur: yeah, we'll have to take a RC as well | 14:54 |
| dansmith | it's going to be super offline | 14:54 |
| dtantsur | I know, hence my concern :) | 14:54 |
| dansmith | yup | 14:54 |
| dtantsur | one mistake - and the cloud is in a very strange state | 14:55 |
| dansmith | but that's the risk of skip level upgrades, | 14:55 |
| dansmith | you're taking the complexity of skipping into your own hands | 14:55 |
| dansmith | it's a tradeoff of complexity and downtime for infrequent upgrades | 14:55 |
| dtantsur | okie, but how is the command invokation going to look? | 14:55 |
| dansmith | that's been a core part of my messaging on the topic at least :) | 14:55 |
| dansmith | nova-manage db migrate-ironic-things --resource_class 'undercloud' --do-all-make-my-db-hurt | 14:56 |
| dtantsur | $ nova-migrate-to-pike <host> --node <uuid>=<class> --node <uuid2>=<class2> | 14:56 |
| dtantsur | ? | 14:56 |
| dtantsur | dansmith: wait, tripleo uses one resource class, but that does not mean everyone does | 14:56 |
| jaypipes | dansmith: would you be able to attend this session in Denver? https://etherpad.openstack.org/p/queens-PTG-skip-level-upgrades | 14:56 |
| dansmith | or if you have different ones, then: | 14:56 |
| dansmith | nova-manage db migrate-ironic-things --resource_class 'undercloud' --host foo1 | 14:56 |
| dansmith | dtantsur: sure, that means you have to do your hosts one at a time with a rc then | 14:57 |
| dtantsur | dansmith: host == ironic node, not nova-compute process, right? | 14:57 |
| dansmith | jaypipes: um yes? been working on this with lyarwood :) | 14:57 |
| dtantsur | (sorry, I always confuse the terms) | 14:57 |

| mriedem | we do have this compute_nodes.mapped column now | 15:01 |

| dansmith | mriedem: not really a good idea, I don't think | 15:02 |
| dansmith | mriedem: we'd have to bump that for all the non-ironic computes too if we did | 15:02 |
| mriedem | true | 15:02 |
| mriedem | this is probably going to have to use all sqla orm code, | 15:03 |
| dansmith | and | 15:03 |
| mriedem | since we don't have some query methods you'd need on the objects | 15:03 |
| mriedem | unless you just did ComputeNodeList.get_all and filter in python | 15:03 |

| avolkov | efried: hi | 15:37 |
| *** baoli_ has quit IRC | 15:37 | |
| efried | avolkov Was just about to respond to your ML post about HA/anti-affinity of SR-IOV VFs... | 15:37 |
| *** baoli has joined #openstack-nova | 15:38 | |
| efried | avolkov I think we can do a bit better even within the bounds of the existing placement API (assuming we get nested RPs). | 15:38 |
| efried | ...by chunking the PFs into HA groups. | 15:39 |
| efried | So I don't think you need the ports labeled P1, P2, P3, P4. I think you can label them G1 and G2, spread across your switches. | 15:39 |
| avolkov | efried: some meta group based on those properties? sounds good | 15:40 |
| efried | This gets a little weird in flavor land, though, cause you'd need a separate flavor for each group I think. | 15:40 |
| efried | So you would have one flavor that says "give me two VFs: one from Switch 1 + Group 1; one from Switch 2 + Group 1" | 15:41 |
| efried | Then another that says "give me two VFs: one from Switch 1 + Group 2; one from Switch 2 + Group 2" | 15:41 |
| *** kristia__ has joined #openstack-nova | 15:41 | |
| efried | ...and somehow alternate which one you use to do spawns, so you get saturation of the different ports. | 15:41 |
| *** ssmith has joined #openstack-nova | 15:41 | |
| efried | Using P1/P2/P3/P4 you have that same problem, only twice as bad :) | 15:42 |

| *** yamamoto has quit IRC | 15:43 | |
| edmondsw | i.e., isn't the switch tag essentially a group tag? | 15:43 |

| *** lucasagomes is now known as lucas-afk | 15:46 | |

| edmondsw | I guess what I'm getting at is that you shouldn't need to know switch or port... just groups | 15:48 |

| dtantsur | cool, lemme check our schedule | 15:50 |

| mriedem | dtantsur: i was told 12-1 | 15:51 |
| dtantsur | thnx | 15:51 |
| efried | edmondsw How can you define two groups to ensure you get four separate ports across two separate switches? | 15:51 |
| mriedem | 3pm wednesday would be *after* lunch :) | 15:51 |
| edmondsw | group 1 = one port to sw1 and one to sw2, group 2 = one port to sw1 and one to sw2, then ask for 2 ports in each group | 15:52 |

| *** kristia__ has quit IRC | 15:53 | |
| *** kristian__ has quit IRC | 15:53 | |
| efried | edmondsw But placement doesn't know enough to not give you both VFs from group 1 on the same switch. | 15:53 |
| *** kairo has joined #openstack-nova | 15:53 | |
| edmondsw | efried there aren't 2 ports in group 1 with the same switch | 15:54 |
| efried | Yes, there are multiple VFs on each pport. | 15:54 |
| edmondsw | oh, VFs... | 15:54 |
| edmondsw | I gotcha now | 15:55 |
| efried | And yes, you could conceivably do this same thing with four groups - but enumerating switches might make more sense to the user; and you also want the model to extend to >2 switches, >2 ports per switch. | 15:55 |
| *** psachin has quit IRC | 15:55 | |
| dtantsur | mriedem: okay, sounds good | 15:55 |
| efried | although... avolkov that might actually make more sense. If you always know you want four VFs, you could just tag your PFs in groups so they'll always be spread out. | 15:56 |
| edmondsw | efried how about group 1 = 2 ports to sw1 and group 2 = 2 ports to sw2? | 15:56 |
| efried | edmondsw Then again you'll ask for two VFs from group 1 and they might wind up coming from the same pport | 15:56 |
| edmondsw | yep, k... better for PFs but doesn't help with VFs | 15:57 |
| efried | eh? | 15:57 |
| edmondsw | nm... it doesn't work, so it doesn't work :) | 15:57 |
| edmondsw | I'm not following why you wouldn't tag them with the port, then | 15:58 |
| efried | avolkov In your email example, it's no different than having labeled P1,P2,P3,P4 - but extending to more than four pports (or reducing the problem set to fewer than 4 desired VFs) it makes more sense to think of groups - where the total number of groups is the number of VFs you're going to want from a single allocation request. | 15:58 |
| efried | edmondsw ^^ | 15:58 |
| avolkov | efried: groups are okay if you have the same requirements for each boot request | 16:00 |
| avolkov | efried: with original properties you can ask distinct ports for one boot request and distict switches for another | 16:01 |
| efried | avolkov Yeah, I get it. If they're different, then it makes more sense for each PF to have its own label, and you do your HA/anti-affinity by constructing your flavors appropriately. | 16:01 |
| efried | Problem with that, though, is if you don't have exactly the same number and configuration of SR-IOV cards on all your hosts. | 16:02 |
| edmondsw | will it be possible to request ports on separate identical cards (HA if a card fails)? | 16:02 |
| efried | So it probably makes more sense to *call* them groups anyway, even if they usually/always map to PFs :) | 16:03 |

| *** kristian__ has joined #openstack-nova | 16:09 | |
| efried | There's a big hand-wavey part in the middle there, though, where the scheduler was able to figure out which compute host(s) would be able to honor that request. Is the scheduler (and/or, gods forbid, the placement API) supposed to introspect the port metadata to help with that decision?? | 16:10 |
| sean-k-mooney | efried: yep see my comments in https://review.openstack.org/#/c/463526/ and https://review.openstack.org/#/c/182242/ to this effect | 16:10 |
| sean-k-mooney | no basically before the scheduler starts scheduling today the neutron v2 client api in nova retrives the port from neutorn | 16:11 |
| *** marst_ has joined #openstack-nova | 16:11 | |
| *** marst has quit IRC | 16:12 | |
| sean-k-mooney | if that port is vnic_type direct/macvtap or virtio-forwarder it create a new pcieresutespec object | 16:12 |
| sean-k-mooney | we need to extend that to also read the ha spec and add that to the picerequeste spec so that when tha tis passed to the sceduler/placement it can fufille the requirementes for ha | 16:12 |
| sean-k-mooney | this is what we have imlemented for the feature based scheduing also | 16:13 |
| efried | Yeah, okay, so that's how it works today; but I thought we were trying to move away from that kind of special-casing as we get into placement. | 16:13 |
| sean-k-mooney | efried: yes so in placement i would like to be able to express affinity and anti affintiy | 16:13 |

| efried | Right, so basically placement would need a generic, multi-layer-capable distance/affinity mechanism, and then consumers could model as they see fit within that framework. | 16:17 |
| sean-k-mooney | efried: yes ideally. its just up to the consumers to model the dependcies with traits and netested providers correctly | 16:18 |
| *** shan has joined #openstack-nova | 16:18 | |
| *** marst has joined #openstack-nova | 16:18 | |
| sean-k-mooney | that is easier said then done however | 16:18 |
| sean-k-mooney | ideally i would like to see a request for a bonded port that looked someting like this | 16:19 |
| efried | sean-k-mooney Definitely makes sense for the switch to be a trait on the PF. Or for the switch to be a RP with its PFs nested underneath it. Either way would work. But if these affinity gizmos are separate from traits, then it probably doesn't matter as much how the RPs are nested. | 16:19 |
| sean-k-mooney | neutron port-create --binding:vnic_type=direct --binding:profile={bond=true, bond_mode=active-backup,bound_count=2,bond_antiafinity=pf} --name bond1 private | 16:19 |
| *** marst_ has quit IRC | 16:19 | |
| efried | Where you could conceivably also say bond_antiaffinity=pf,switch ? | 16:19 |
| sean-k-mooney | efried: yes | 16:20 |
| jaypipes | efried: distance would be stored in an aggregate_distances table, which would store the distance between the providers in one aggregate and providers in another. | 16:20 |
| jaypipes | efried: distance would just be a number. higher the number, greater the relative distance. | 16:20 |
| edmondsw | or bond_antiaffinity=card,switch if you want the PFs to come from different physical CNAs? | 16:21 |
| sean-k-mooney | jaypipes: im not sure that distance would be a good match to antiafinity/affinity if i need to manually create agggreates for the vfs but ingeneral it is usefull | 16:21 |
| sean-k-mooney | edmondsw: you could but you see the general pattern i would love to express this requirement on the neutorn port in a general way rather then statically defiened in a flavor | 16:22 |
| edmondsw | sean-k-mooney yeah, and I think I agree with that if we can make it work | 16:23 |
| efried | Now, let me make sure I understand something: placement is never going to be in the business of assigning individual VFs around. It's just gonna decrement the count and say "you got one from this RP". | 16:23 |
| sean-k-mooney | bassically i would like to keep flavor extraspecs for compute requirement | 16:23 |
| *** marst_ has joined #openstack-nova | 16:23 | |
| *** marst has quit IRC | 16:23 | |
| *** trinaths has left #openstack-nova | 16:23 | |
| efried | Then it's up to the virt driver (or maybe the mech driver in this case?) to decide which specific VF to use -- or even to create the VF on the fly if that's something it can do. | 16:23 |
| sean-k-mooney | efried: maybe... i think jay would agree i would not mind extending it to be able to do indvidual assignment | 16:24 |
| jaypipes | sean-k-mooney: it's a possibility. | 16:24 |
| efried | Point is, placement shouldn't be aware of an individual VF any more than it's aware of an individual memory megabyte. | 16:24 |
| jaypipes | sean-k-mooney: in the same way that we agreed not to have aggregates have traits (instead, we "push down" all traits to the resource provider) | 16:25 |
| jaypipes | efried: not necessarily. | 16:25 |
| dansmith | jaypipes: eh? | 16:25 |
| efried | jaypipes: eh? | 16:25 |
| jaypipes | efried: if you need to differentiate between two VFs on a host because those two VFs expose different capabilities, then you will need to create each different VF as a resource provider. | 16:26 |
| sean-k-mooney | efried: well i would like to have the mem_page resouce provider track indiviual pages too but i have more importing things to adress first | 16:26 |
| *** rajathagasthya has joined #openstack-nova | 16:26 | |
| dansmith | ah, sure | 16:26 |
| efried | Okay, yeah. | 16:26 |
| dansmith | not sure when/how that would happen | 16:26 |
| dansmith | but if it did, then I guess | 16:26 |
| dansmith | although then we're going to have a shitton of single-resource providers | 16:26 |
| jaypipes | dansmith: ask sean-k-mooney. Intel excels at creating uses for complexity. | 16:26 |
| dansmith | I'd hope that you could separate that into 32 VFs with tls-offload and 32 without, for a 64-vf nic | 16:27 |
| efried | okay, as long as the general case is to have the inventory of VFs just be a number. | 16:27 |
| dansmith | but.. | 16:27 |
| dansmith | efried: it's still that, | 16:27 |
| dansmith | efried: you'd just have inventory=1 for these | 16:27 |
| efried | yeah yeah. | 16:27 |
| efried | I get it. | 16:27 |
| efried | But the tls-offload thing... | 16:27 |
| sean-k-mooney | well i can certenly do a lot with singel-resouce proverders | 16:28 |
| efried | I would really hope there would be some other way to specify that. | 16:28 |
| *** annegentle has quit IRC | 16:28 | |
| dansmith | efried: I wouldn't | 16:28 |
| jaypipes | sean-k-mooney: would single resource providers provide spell checking? :) | 16:28 |
| sean-k-mooney | haha perhaps... | 16:28 |
| dansmith | efried: tls-offload being a trait for regular nics, and vfs, so if some have it and some don't... | 16:28 |
| jaypipes | sean-k-mooney: :P | 16:28 |
| efried | But if I create my VFs on the fly, and could assign that trait to any one of 'em on the fly (say, based on a prop in the binding profile)... | 16:29 |
| jaypipes | dansmith, efried: technically you wouldn't necessarily need to have single resource providers for each VF. just one resource provider per set of VFs with similar capabilities. | 16:29 |
| dansmith | efried: no, that's not the same | 16:29 |
| dansmith | jaypipes: right exactly | 16:29 |
| *** itlinux has joined #openstack-nova | 16:29 | |
| * jaypipes runs away before calling it pci device pools. | 16:29 | |
| dansmith | efried: I meant if some VFs would be unable to provide tls offload, then they go in a separate provider without that trait | 16:30 |
| sean-k-mooney | so our current generation of nics cant do this but in future nics we will be able to load firmware that gives different feature per vf | 16:30 |
| dansmith | efried: if they all can and it's a by-request thing, then that means they're all in one provider with that trait and the virt driver decides to configure it as such based on the request | 16:30 |
| *** kristian__ has joined #openstack-nova | 16:30 | |
| sean-k-mooney | with fortvile XL710 its card wide | 16:30 |
| sean-k-mooney | so all vf would have same features/tratis | 16:30 |
| dansmith | sean-k-mooney: yeah and we're all REALLY glad for that | 16:30 |
| dansmith | (not) | 16:30 |
| efried | dansmith Ah, exactly what I was getting at earlier, but you said you didn't want. | 16:30 |
| dansmith | efried: huh? | 16:31 |
| dansmith | efried: a request has a list of required and preferred traits | 16:31 |
| jaypipes | dansmith: don't tempt sean-k-mooney. he will call up the hw designers and ask them to rework it to be more complicated :P | 16:31 |
| *** marst has joined #openstack-nova | 16:31 | |
| dansmith | efried: what I said was I didn't want virt-specific communication from the api user to the virt driver | 16:32 |
| *** marst_ has quit IRC | 16:32 | |
| sean-k-mooney | haha well i did ask them to make atleas per pf instead of per card... | 16:32 |
| dansmith | efried: this is not that, this is a generic and abstract requested trait.. placement has already filtered out virt hosts that can't do that generic thing | 16:32 |
| efried | okay, "preferred trait" is new to me. | 16:32 |
| dansmith | efried: doesn't matter, required trait is the same | 16:32 |
| dansmith | for this example | 16:32 |
| sean-k-mooney | efriad: the idea was the required traits would be enforced by filter and prefered trais would be consumed by weigher | 16:33 |
| dansmith | sean-k-mooney: and both could feed into how the virt driver does something eventually | 16:33 |
| sean-k-mooney | yes | 16:34 |

| sean-k-mooney | efried: i think physnet can be a standard trait prefix. so NW_PHYSNET_XXX | 17:07 |
| efried | Okay; I thought you weren't allowed to create a trait with anything other than a CUSTOM_ prefix. | 17:08 |
| efried | But that wasn't really my question. | 17:08 |
| *** harlowja has joined #openstack-nova | 17:08 | |
| sean-k-mooney | efried: this was one of the usecases i wanted to have key value traits for originally but standard prefixes i think are ok too | 17:08 |
| efried | My question is: who's responsible for recognizing that the XXX corresponds to the physnet in the neutron port? | 17:08 |
| *** Apoorva has joined #openstack-nova | 17:09 | |
| sean-k-mooney | efried: technically yes but lacking key value traits i was hoping we could have a set of stadard prefixes that you were also allowed to create. phynets is one the other option is to have physnet be a field of resouce class | 17:09 |
| *** shan has joined #openstack-nova | 17:09 | |
| efried | Okay, but who's responsible for recognizing that the XXX corresponds to the physnet in the neutron port? | 17:10 |
| sean-k-mooney | efried: well if nova reads the phynet form the port it can compute the trait name and placement can then just do a sting match | 17:10 |
| efried | That would be one way... is that how it's going to work? Or is this still part of the open discussion? | 17:11 |
| *** kristian__ has joined #openstack-nova | 17:11 | |
| sean-k-mooney | still open. i was also thinking of ways to have neutron pass traits/resouce prodier request to nova so that nova does not have to compute the trait name | 17:12 |
| sean-k-mooney | for example addint a traits field to the vif_binding details with the physnet name trait so that nova does not have to query neutron for the physnet | 17:13 |
| sean-k-mooney | again this is up for discussion | 17:13 |

| vdrok | hrm, not in ironic docs I think. | 17:17 |
| sean-k-mooney | nova is currently the main thing interacting with traits and placement but i would like to add some knolowe of those apis to neutron so that nova does not have to know as much deails about the networking contriants going forwand and can jsut fowrad the reques for resouce providers and traints form neutorn. | 17:17 |
| mriedem | sean-k-mooney: i think mlavalle already started something like a placement client in neutron a few releases ago | 17:18 |
| sean-k-mooney | mriedem: cool we will need if for thinks like bandwith qos. e.g. if we model bandwith in placement and you increase the minium bandwith for a port i should go to placement and check that there is capasity left and increase the claim if so or fail the requst if not | 17:20 |
| sean-k-mooney | e.g. if port is bound it should only allow bandwith to be increased if placement says there is capasity to do so and provide error to user if it cannot | 17:21 |

| *** david-lyle has quit IRC | 17:30 | |
| *** suresh12 has quit IRC | 17:31 | |
| sean-k-mooney | jaypipes: correct today. i was hopping we could add them if we were going to use them for standard thing like physnets to differenciate them for user created traits | 17:31 |
| sean-k-mooney | basically any traint that does not start with custom_ i consider to be a trait that must be defiend in os-traits | 17:32 |
| jaypipes | sean-k-mooney: I would oppose that. traits are boolean values. | 17:32 |
| *** gouthamr has quit IRC | 17:32 | |
| jaypipes | sean-k-mooney: the physical network that a NIC is associated with must be a custom trait. | 17:33 |
| sean-k-mooney | but just as we have defiend the custom_ as a user defiend prefix i was hoping we could have other prefiex reseved for internal use such as the physnet | 17:33 |
| jaypipes | sean-k-mooney: why though? | 17:33 |
| jaypipes | sean-k-mooney: what benefit does that bring? | 17:33 |

| dansmith | o.O | 17:35 |

| sean-k-mooney | we need to apply physnets to all sriov vf otherwise we cant use them with neutron networks | 17:35 |
| jaypipes | there's no such thing as a "standard physnet"... | 17:35 |
| jaypipes | it's a named entity | 17:36 |
| sean-k-mooney | yes we cant standaries the full trait because its just a config option | 17:36 |
| sean-k-mooney | hence haveing a standard prefix | 17:36 |
| jaypipes | no, it's not a config option... it's an attribute of the port profile isn't it? | 17:36 |
| sean-k-mooney | no | 17:36 |
| dansmith | not for sriov right? | 17:36 |
| sean-k-mooney | it a neutorn and nova config option | 17:36 |
| dansmith | but even still, those'll all have to be custom ones anyway right? | 17:37 |
| sean-k-mooney | for sriov its set in the pci whitelist | 17:37 |

| jaypipes | what dansmith said. | 17:37 |
| sean-k-mooney | well no because i have no ideay which pci device is connected to which phyical network unless you tell me | 17:37 |

| jaypipes | dansmith: he's saying "you" as in the nova.conf setting. | 17:38 |
| *** liverpooler has quit IRC | 17:38 | |
| sean-k-mooney | yes its not automatically discoverable so we have to declare it statically in the nova.conf | 17:38 |
| dansmith | we will probably have to do something like we were going to do for ironic, which is synthesize CUSTOM_PHYSNET_$thing_in_your_config | 17:38 |
| jaypipes | i.e. unless the nova.conf pci whitelist indicates which PCI devices are asssociated with which physnet, there's no way for code on the compute host to know. | 17:38 |
| dansmith | sean-k-mooney: right, I know | 17:38 |
| dansmith | sure | 17:39 |
| dansmith | we have that today | 17:39 |
| sean-k-mooney | dansmith: yes so when we systesize traiths i was suggesting uses a prefix other then custom to do that | 17:39 |
| dansmith | sean-k-mooney: yeah but that does't work | 17:39 |
| dansmith | sean-k-mooney: because anything but a CUSTOM_ is a hard enum in a library | 17:39 |

| *** armax has joined #openstack-nova | 17:40 | |
| sean-k-mooney | dansmith: correct so im suggesting that we extend os tratis to have other prefixes that are not enums. if that is not desirabel then CUSTOM_ works too | 17:40 |

| rybridges1 | Hello all | 18:20 |
| rybridges1 | I had a quick question about nova cells | 18:20 |
| rybridges1 | We are currently attempting to deploy a fresh ocata cluster. I was wondering if [cells] section of nova.conf is required for cells v2 at all? I read in the comments that the stuff under that section is only for cells v1, but just wanted to make sure | 18:21 |
| *** karthiks has joined #openstack-nova | 18:22 | |
| melwitt | rybridges1: that's correct. see 4. on the FAQ, [cells] section is not to be used https://docs.openstack.org/nova/latest/user/cells.html#faqs | 18:23 |
| efried | jaypipes We were talking last week about how to model e.g. minimum egreess bandwidth support on SR-IOV VFs. | 18:24 |
| rybridges1 | Okay great! Thanks melwitt | 18:24 |
| jaypipes | efried: who is we? :) | 18:25 |
| efried | dansmith suggested we would model the PF as a RP with e.g. SRIOV_VFS=48,EGRESS_BW_PCT=100 | 18:25 |
| efried | So that basically you would grab some number of VFs and some percentage of the bandwidth, and whichever you exhausted first would take that PF out of the running for subsequent requests, kind of thing. | 18:26 |
| efried | First of all, is this along the lines of what you've been thinking? | 18:26 |
| efried | Doesn't have to be percentage; could be bps or whatever; point is the number of VFs and the total bandwidth are separate but parallel resource classes in the RP. | 18:27 |
| cdent | “parallel”? | 18:27 |
| efried | just meaning that they're RC inventories on the same RP | 18:27 |
| * efried will stop trying to invent terminology | 18:28 | |
| cdent | isn’t that what we do around here? | 18:28 |
| efried | Some of us shouldn't. | 18:28 |
| jaypipes | efried: yep. that's pretty close. I don't like the pct versus using bytes_per_sec but yeah. | 18:29 |
| jaypipes | efried: in fact, that's pretty close to what I had written on the ML, no? | 18:29 |
| efried | jaypipes okay, so help me fill in the gaps here. | 18:29 |
| efried | IRL I'll have multiple PF-y RPs, and let's say they each have both of those RC inventories defined. | 18:30 |
| jaypipes | k | 18:30 |
| efried | When I make a request for, say, SRIOV_VFS=1,EGRESS_BW_PCT=20 -- what's to stop placement from allocating the VF inventory from one RP and the egress bandwidth inventory from another?? | 18:31 |

| jaypipes | efried: I don't know how to structure a request that would impart the required information for this query :( | 19:53 |
| efried | jaypipes Well, shit, if YOU can't do it.... | 19:54 |
| efried | Adding to list. | 19:54 |
| jaypipes | efried: we would essentially need to replicate child-parent information in the request for resources. in other words, the requestor must know that a VF is a child of a PF is a child of a compute host. | 19:54 |
| jaypipes | efried: and we can't ask the user to know that relationship... | 19:55 |
| *** esberglu has quit IRC | 19:55 | |
| efried | jaypipes But the alternative is making them separate resource classes. Which doesn't seem right at all. | 19:55 |
| jaypipes | efried: no, that doesn't work either... | 19:55 |
| jaypipes | efried: because their not separate resource classes. they're separate providers. | 19:56 |
| jaypipes | efried: just imagine for a second how one might ask AWS for such a thing. | 19:56 |
| * efried doesn't know from AWS | 19:56 | |
| jaypipes | efried: you can't. | 19:56 |
| efried | uhm | 19:57 |
| jaypipes | efried: you need a more complicated DSL like CloudFormation or TOSCA | 19:57 |
| efried | So how are we planning to model e.g. asking for more than one cinder volume? | 19:57 |
| jaypipes | efried: and an orchestrator that would take one of those request templates and produce multiple requests to EC2 APIs. | 19:57 |
| jaypipes | efried: we don't. that's the very reason why we've pushed back on having the compute API be an orchestration system. | 19:58 |
| mriedem | prometheanfire: i think i've got these xenapi unit tests fixed | 19:58 |
| mriedem | should have a patch up shortly | 19:58 |
| prometheanfire | cool | 19:58 |
| jaypipes | efried: you want >1 cinder volumes? then create them in cinder and attach them to your compute instance. | 19:58 |
| *** suresh12 has quit IRC | 19:58 | |
| prometheanfire | if that merges today then the xenapi change can go in tomorrow via bot update | 19:58 |
| jaypipes | efried: there is absolutely no "atomically create 10 volumes in Cinder" command. | 19:59 |
| *** tidwellr has left #openstack-nova | 19:59 | |
| *** priteau has joined #openstack-nova | 19:59 | |
| mriedem | there isn't?! | 19:59 |
| jaypipes | efried: and these kinds of requests that the VNFM would be making are essentially that: requests for a set of related resources to be created as an atomic unit. | 19:59 |
| efried | jaypipes Seems like there should be a way to specify multiple `resources=` keys in a single request, kind of thing. | 20:00 |
| mriedem | how about i request 10 VMs with block_device_mapping_v2 in the request, of size 10, for each entry with different device names so nova creates the volumes! | 20:00 |
| jaypipes | incidentally, this is why there's no atomicity guarantees that *any* orchestrator provides. not k8s, not heat, not IBM "smart" cloud orchestrator. not any of them. | 20:00 |
| mriedem | does sco still exist? | 20:00 |

| jaypipes | efried: again, you can already do that. | 20:54 |
| efried | jaypipes With placement? | 20:54 |
| efried | Maybe I misunderstood the previous conversation. But I thought that was exactly my point: you can do it today, but you won't be able to do it tomorrow. | 20:55 |
| jaypipes | efried: no, not with placementy. | 20:55 |
| jaypipes | efried: you can currently do it with the physnet tag hack in the pci_passthrough_whitelist thing. | 20:56 |
| jaypipes | efried: and pre-creating Neutron ports with matching physnet tags | 20:56 |
| jaypipes | efried: and passing those ports in to the Nova boot request | 20:57 |
| *** slaweq_ has quit IRC | 20:57 | |
| *** slaweq_ has joined #openstack-nova | 20:58 | |
| efried | jaypipes Right. And I *thought* part of what we were trying to move toward is getting rid of the current PCI setup in favor of having device (incl. PCI) management revolving around placement. | 20:58 |
| jaypipes | efried: what you're asking for here is combining the PCI device manager and PCIPassthroughFilter's behaviour of selecting a specific device based on arbitrary tags in the pci_device_request into the placement API. | 20:58 |
| efried | jaypipes Well.... yes. | 20:58 |
| *** tbachman has joined #openstack-nova | 20:59 | |
| efried | I'm asking what's the answer to that ^ gonna be when we've gotten rid of the PCI device manager and moved to Placement nirvana. | 20:59 |
| jaypipes | efried: I'd like to be storing structurally-correct data in the placement DB, yes. that means nested resource providers, support for traits, and linking the (generic) device manager with support for both setting traits and inventory on a tree of provider records. | 20:59 |
| dansmith | efried: the people that want to attach multiple physical networks to vms are the same people that ultimately keep most of us employed you know | 21:00 |
| jaypipes | efried: what I *don't* see a way to do -- again, without crazypants complex DSLs -- is a way to reproduce the PciPassthroughFilter and NUMATopologyFilters as REST API requests to placement | 21:00 |
| dansmith | efried: I don't think we'll deprecate or remove legacy structures from nova before we have a way to replicate critical behavior like that using something else.. not sure where you got that idea | 21:00 |
| jaypipes | efried: it's the "how do I request all these related things from the placement REST API" part that has me stumped, not the "please store this structured data in the placement DB" part. | 21:01 |
| efried | jaypipes Right, I can see how to get the structure/inventory data into placement. | 21:02 |

| efried | dansmith Sorry it came across that way; I misunderstood some stuff. | 21:03 |

| *** Apoorva has quit IRC | 21:06 | |
| dansmith | efried: I think what he was saying was that expecting nova to do lots of steps for you (i.e. determine and reserve multiple resources) as part of a single boot request is really getting into orchestration | 21:06 |

| openstackgerrit | Brianna Poulos proposed openstack/nova master: Add trusted_certificates to REST API https://review.openstack.org/486204 | 21:07 |
| efried | So I'm confused as to how VCPU+MEM_MB+DISK_GB isn't determining and reserving multiple resources. | 21:07 |
| dansmith | efried: are you just being sarcastic and difficult now? | 21:07 |
| dansmith | obviously that's not | 21:07 |
| *** penick has quit IRC | 21:07 | |
| efried | No, dansmith, I'm actually this obtuse I'm afraid. Mostly from lack of experience (and a disproportionate lack of inhibition to speak up and ask questions). | 21:08 |
| efried | But again, apologies, I think I understand what you mean now. | 21:08 |
| efried | when you said "multiple resources" | 21:08 |
| efried | you meant "multiple disparate resources of the same class". | 21:09 |
| efried | mahbad. | 21:09 |
| jaypipes | efried: hold up... I just thought of something... gimme a minute to flesh it out in my brain. | 21:09 |
| efried | btw jaypipes I realized as I started typing it why the 'multiple querystring keys' thing is a nonstarter if traits is its own qs key... | 21:09 |
| dansmith | efried: I mean things like nova going to cinder to create, image, and attach a volume, and to neutron to create multiple ports for a complex network layout, and then to some other service to arrange for party balloons to be sent in ten minutes, and then, finally, to boot the instance | 21:10 |
| efried | dansmith Rightright. And I think again the reason I'm confused as to why we wouldn't want that is because that (at least the neutron & cinder stuff) is part and parcel of what nova does today, and therefore what I think of as being in nova's purview. | 21:11 |
| efried | and if we're not taking away at least the neutron &/| cinder stuff, then presumably there's going to have to be an answer for it in the placement world. | 21:12 |
| efried | which solution, if we're gonna solve it for neutron & cinder, would seem like it oughtta work for whatever. | 21:12 |
| efried | although I'm *not* suggesting it should go talk to just any external service. | 21:13 |
| *** harlowja has quit IRC | 21:13 | |
| *** itlinux has joined #openstack-nova | 21:13 | |
| dansmith | I don't follow | 21:14 |
| efried | In the case of neutron, the model we have today for VFs is that you create your ports in neutron and then some gizmo in nova knows to associate that with the physnet tags from the [pci]passthrough_whitelist (which is one of jaypipes's bugbears) | 21:14 |
| dansmith | we're not talking about getting rid of neutron or our talking to it, but just not trying to build requests for complex things into nova's API, IMHO | 21:15 |
| dansmith | I think I've lost track of why this is coming up in the context of placement | 21:15 |
| *** edmondsw has joined #openstack-nova | 21:16 | |

| efried | dansmith Well, the premise - which I *think* started with jaypipes (see comments here https://review.openstack.org/#/c/497965/) - is that we want to phase out the PCI device management gorp that's been frankensteined over the years. | 21:17 |

| *** baoli has quit IRC | 22:30 | |
| jaypipes | efried: no, I can come up with an *internal* representation for the request. what I can't figure out is how to map that to a *single* REST API call. | 22:30 |
| efried | Right. | 22:30 |
| efried | jaypipes Don't kill me don't kill me but... what if I numbered the query param keys? | 22:31 |
| efried | resources1=...&traits1=...&resources2=...&traits2=... | 22:32 |
| jaypipes | efried: uhm, eww? :) | 22:32 |
| efried | Well, yeah it's eww, that's a given. But it's clear that it could work. | 22:32 |
| efried | It could also conceivably answer the thing where it matters what order we attach devices in... | 22:33 |
| efried | ...which some people care about. | 22:33 |
| jaypipes | efried: not sure I follow why the attachment order matters to the placement API. | 22:33 |
| efried | It doesn't, but when the request comes in, don't those keys come through? Mebbe not, sorry. | 22:33 |
| efried | Anyway, for the general case, non-numbered querystring keys work just fine; in fact they don't even have to be numbers - we just parse the prefix and group by the suffix, whatever it is. | 22:35 |
| jaypipes | efried: the problem with adding this to the placement REST API is that then we're adding a bunch of orchestration-like logic into the placement service. | 22:36 |
| jaypipes | efried: instead of keeping that out of placement and relying on the caller to placement understanding that the request contains a number of "subrequests" that are for specific complex types. | 22:36 |
| efried | jaypipes Yeah, I admit I don't understand what is meant by "orchestration" and where that line is drawn. | 22:37 |
| jaypipes | efried: dealing with lots of resources as a group is orchestration. | 22:37 |
| jaypipes | efried: where the relationship between the resources, the dependencies between them, the constraints that each imposes on each other, etc. that's orchestration. | 22:38 |
| jaypipes | efried: whereas placement is designed to be a fast, efficient method of determining providers of resources for a given simple request for capacity. | 22:38 |
| *** tbachman has joined #openstack-nova | 22:40 | |
| cdent | jaypipes: can you clarify something for me: I’m not fully grokking why, in your paste, we need to make multiple requests to /a_c ? Is it is because at the point we don’t have a good way to express (in one request) what we want or is there more than that? | 22:41 |
| efried | jaypipes I'm probably being obtuse again, but I still don't really see how what we're talking about here doesn't still fall into that description. Placement is designed to grab resources from multiple resource providers. From a way-zoomed-out view, saying "you can only get stuff from a given resource class from a single provider" seems like an arbitrary limitation. Zoom back in, and it's one that seems imposed because we | 22:42 |
| efried | 're having trouble expressing it under the current design, not because it inherently crosses the line to "orchestration". | 22:42 |
| cdent | jaypipes: on line 50 it is GROUP_A on the first go round and GROUP_B on the second? | 22:42 |
| *** claudiub|2 has quit IRC | 22:43 | |
| efried | cdent Yeah; and/or L49 could be different egress bandwidth numbers | 22:43 |
| cdent | thanks | 22:43 |
| jaypipes | cdent: a couple reasons for that. the first is that it's difficult for me to map the concept of related sub-requests in a single REST API call (again, without resorting to some DSL-ish request payload) and b) because I suspect these types of use cases are just the tip of the iceberg and that the logic that relates various things with each other (GPUs, FPGAs, NIC HA groups, etc) will be different and not possible to cleanly express with simple | 22:44 |
| jaypipes | query parameters. | 22:44 |
| * cdent nods | 22:44 | |
| jaypipes | cdent: and yes, it would be GROUP_A on the first go around and GROUP_B on the second. | 22:44 |
| cdent | jaypipes: next question: step 4 sounds like a pretty big step backwards for the goals we originally expressed for allocation_candidates | 22:45 |
| jaypipes | cdent: could also have different amounts of egress bandwidth, different affinity policies, different all sorts of things, frnakly | 22:45 |
| jaypipes | cdent: Yupppp! | 22:45 |
| cdent | why can’t we have a complete allocation_requests (just to be explicit) | 22:45 |
| *** Apoorva_ has quit IRC | 22:45 | |
| jaypipes | cdent: it removes the whole opaqueness aspect of the allocation request :() | 22:45 |
| cdent | yes much :( | 22:45 |
| efried | Is it because the allocation request is keyed by resource class? | 22:46 |
| efried | (haven't looked at that guy yet) | 22:46 |
| *** Apoorva has joined #openstack-nova | 22:46 | |
| jaypipes | cdent: we can't have a complete allocation_requests unless placement is passed all of the logic about relationship between sub-resources | 22:46 |
| cdent | I thought that’s what nested was providing us? | 22:47 |
| jaypipes | efried: the allocation request is not keyed by resource class, no. | 22:47 |
| jaypipes | efried: the allocation request is essentially the request payload to PUT /allocations/{consumer_uuid} | 22:47 |
| openstackgerrit | Michael Still proposed openstack/nova master: Add release note for requiring shred 8.22 or above. https://review.openstack.org/501022 | 22:47 |

| cdent | jaypipes: related, have you yet seen: http://lists.openstack.org/pipermail/openstack-dev/2017-September/121824.html from avolkov ? | 22:48 |
| efried | jaypipes And it must be able to contain resources from different RPs. So why would there be a limitation that RCs therein be unique? | 22:48 |
| efried | cdent That's what started this whole thing :) | 22:48 |
| *** edmondsw has joined #openstack-nova | 22:48 | |

| cdent | presumably the response to option 2 is “no” | 22:49 |
| cdent | as that’s not "real" | 22:49 |
| jaypipes | cdent: nested resource providers allows the placement API to understand whether, say, a PF that provides some VFs is on a particular compute node. Nested providers doesn't, however, solve the problem of how do we model the *request* for resources when the user doesn't know that there is a nested relationship between things. | 22:49 |
| jaypipes | efried: there is no such limitation. I'm not sure what you're getting at. | 22:49 |
| mikal | mriedem: I am a bad man and realized once that shred patch had merged that it probably should have had a reno, so I've added one in https://review.openstack.org/#/c/501022/ | 22:50 |
| *** esberglu has joined #openstack-nova | 22:50 | |
| efried | jaypipes What you and cdent were saying about breaking opaqueness? And a step backwards for original goals of allocation_candidates. I didn't catch where that came from. | 22:51 |
| cdent | jaypipes: I get that the request modeling is a limitation, but if were to set that aside for a moment and we could express the request well then the we could present a complete set of allocations in response, right? The limitation as described in your paste is because the current request doesn’t have all the state. | 22:51 |
| cdent | efried: ideally it would be possible to take the first item in the allocation_request list and send that to /allocations/{consumer_uuid} without modifications to make a “claim” | 22:52 |
| efried | cdent Why doesn't that still work in this scenario? | 22:52 |
| jaypipes | efried: the items in the "allocation_requests" part of the HTTP response for the GET /allocation_candidates placement API call is intended to be able to pass as-is (i.e. opaquely without the caller needing to know the structure of the HTTP payload) to the PUT /allocations/{consumer_uuid} call.' | 22:52 |
| *** edmondsw has quit IRC | 22:52 | |
| cdent | but if you’ve used multple requests to construct the set of rps, we don’t have enough info to construction all the pieces of the allocation | 22:52 |
| jaypipes | cdent: correct. | 22:53 |
| cdent | feh | 22:53 |
| efried | Okay, I don't understand that, but I'm sure it's because I haven't read everything yet. | 22:53 |
| cdent | efried: if you haven’t got it after some cogitation, ask me again a bit later and I can try to explain it using different words | 22:54 |
| cdent | we’re making some shortcuts in our explanations that aren’t really helping matters | 22:54 |
| jaypipes | cdent: thus my earlier comment that "fuck it..." we will probably end up needing yet another REST API call to placement that takes as a payload some crazypants HOT template|TOSCA YAML|CloudFormation template thing that describes all the various components of the instance that the user wants Nova to atomically claim and spawn. | 22:54 |

| dansmith | needs a reno but I'm out of brain power and the smoke is cutting my oxygen supply | 22:57 |
| efried | cdent jaypipes So what we're talking about here is that we made an architectural call to be able to take a chunk of the placement response and just blat it into a (single) allocation request; but if we've made multiple calls to placement we'll have multiple such chunks, and there's currently no semantic for "combining" them into a single allocation request. | 22:57 |
| efried | Did I get that right? | 22:58 |
| cdent | jaypipes: sadly, somewhere is going to have to have a model for that tosca thing for an instance doign nested rp stuff and it is going to need to land on a compute (so the instance can build correctly). we planned ourselves into this corner, is just the way the world is for now :( | 22:59 |
| cdent | efried: yes, pretty much. we’d need to build that “reassembler” in the scheduler and in a perfect world wouldn’t have to | 22:59 |
| efried | In practical terms, the "opaque" allocation request is just a list of things, and we would just append those lists together and be fine. We just didn't wanna have to do that. | 23:00 |
| cdent | we now need to be smart in at least two spots | 23:00 |
| cdent | efried: not exactly. | 23:00 |
| cdent | If we are lisp coders and are talking about this problem, then yes, we building lists | 23:01 |
| cdent | but the selection of pieces is not just reassambling a sequence | 23:01 |
