| mriedem | efried: setting CONF.neutron.auth_type is going to be required to talk to neutron using ksa right? | 14:50 |
| efried | mriedem: I believe so, yes. | 14:50 |
| efried | uh | 14:50 |
| efried | unless you're going the admin path. | 14:50 |
| mriedem | that's what i was worried about, | 14:50 |
| efried | then you're just using admin auth. | 14:50 |
| mriedem | but if you get here and auth_type is None, http://git.openstack.org/cgit/openstack/nova/tree/nova/network/neutronv2/api.py#n75 | 14:50 |
| efried | which is CONF.something-other-than-neutron.auth_type, I imagine. | 14:50 |
| mriedem | then you've f'cked up right? | 14:50 |
| efried | hum, that code shouldn't be in nova at all. If you had no auth type, that ksa loading shoulda kicked an exception. | 14:51 |
| efried | I'll have to go paw through the ksa code again, gimme a few... | 14:52 |

| mriedem | efried: right, ok, point is i'm trying to know if/when i can log something useful in the logs for when you don't configure nova to talk to neutron https://bugs.launchpad.net/nova/+bug/1761487 | 14:56 |
| openstack | Launchpad bug 1761487 in OpenStack Compute (nova) "Nova, Unexpected API Error while creating VM" [Undecided,Invalid] | 14:56 |
| mriedem | we get that same bug at least weekly | 14:56 |
| *** belmoreira has quit IRC | 14:57 | |
| efried | mriedem: This would be very similar in spirit to what imacdonn noted above. We used to try to determine whether you'd configured placement based on whether [placement]os_region_name was present. Which isn't the best way to do it, because that guy can default - auth_type would have been a better one to check. | 14:58 |
| efried | mriedem: Which leads me to this one: you could have a similar check for neutron config. Though I don't know whether neutron is required to make the world work, so having the check up front may be too aggressive. | 14:58 |
| efried | mriedem: But yeah, you could at least make that error message that you pointed out more clear. | 14:59 |
| efried | mriedem: "You need to configure the [neutron] section of your conf with ksa Adapter options." | 14:59 |
| efried | kind of thing. | 14:59 |
| *** yangyapeng has joined #openstack-nova | 14:59 | |
| zigo | o/ | 15:00 |
| mriedem | neutron is required yeah, because we assume port binding is available in neutron and the port binding extension is an admin-only extension by default | 15:00 |
| kashyap | zigo: Hi there ... so to follow-up, all the distributions in the DistroSupportMatrix have libvirt 3.8.0 and QEMU 2.9.0 | 15:00 |
| *** abhishekk has quit IRC | 15:00 | |
| mriedem | efried: so i'll start small with that kind of log message if we hit this, | 15:00 |
| zigo | I haven't tried backporting libvirt & qemu to Stretch, could you give me some time so I can tell if it's painful or not? | 15:00 |
| kashyap | zigo: This is the wiki: https://wiki.openstack.org/wiki/LibvirtDistroSupportMatrix | 15:00 |

| *** ratailor has joined #openstack-nova | 15:00 | |

| kashyap | zigo: Sure. Please respond here: http://lists.openstack.org/pipermail/openstack-dev/2018-April/129048.html | 15:00 |

| zigo | kashyap: You can just scrap Jessie from your table, it's unsupported already, and maybe add Sid. | 15:12 |
| zigo | That's what counts for me. | 15:12 |
| kashyap | zigo: "Sid" == Testing / unstable, isn't it? | 15:12 |
| kashyap | zigo: Isn't it "Buster" that's the upcoming release? | 15:12 |
| * kashyap learnt a bit too much (?) about Debian release structure last week :P | 15:13 | |
| zigo | kashyap: Generally, we have sid == buster, package migrate in 5 days from Sid to Buster if there's no RC bug. | 15:13 |
| kashyap | zigo: "Also ... it's a wiki, feel free to update it" :-) | 15:13 |
| zigo | :) | 15:13 |
| kashyap | zigo: When I checked earlier this week, there was no ETA for Buster (love saying it out loud) | 15:14 |
| zigo | Sure, that's what Debian is about: it's ready when it's ready, no commercial agenda. | 15:14 |
| bauzas | dansmith: mriedem: melwitt: FYI, I had a family loss this week, so I won't be around tomorrow | 15:14 |
| zigo | What's surprising is that there's still no freeze date. | 15:14 |
| kashyap | zigo: Either way, if you see, we're trying to converge on a reasonable least common denonimnator version for libvirt / QEMU across releases | 15:14 |
| *** moshele has joined #openstack-nova | 15:14 | |
| dansmith | bauzas: ack :( | 15:14 |

| stephenfin | sean-k-mooney: I recall a blueprint that would allow us to determine what networking backend was running on a host (I guess so you could mix hosts OVS-DPDK and OVS kernel). Got a link, if so? | 15:42 |
| * stephenfin has hardware again and is trying to find a way to make NUMA-aware vSwitch less icky | 15:42 | |
| mriedem | stephenfin: wouldn't that information be in the port's host binding details? | 15:43 |
| *** andreas_s has quit IRC | 15:43 | |
| stephenfin | mriedem: Possibly, but we don't do any of that stuff until we land on a host, far as I can tell | 15:46 |
| *** jackie-truong has quit IRC | 15:46 | |

| stephenfin | bauzas: Sorry to hear it :( | 15:48 |
| bauzas | stephenfin: no worries, it was expected | 15:48 |
| sean-k-mooney | mriedem: that info is not in the port until after binding | 15:48 |
| sean-k-mooney | stephenfin: i dont think it was in a seperat spec but it was part of the bandwith based scheduling spec | 15:49 |
| stephenfin | sean-k-mooney: Hmm, OK. Was hoping I could steal some ideas from said spec | 15:49 |
| *** Spaz-Work has quit IRC | 15:49 | |
| sean-k-mooney | the intent was to use traits for neturon extention or backend to select the backend. the trati would be added to the neutron port resouce reuest | 15:50 |
| stephenfin | So you'd be querying placement? | 15:50 |
| sean-k-mooney | stephenfin: well you can proably steal them from the bandwith spec. | 15:50 |
| sean-k-mooney | stephenfin: yes | 15:50 |
| sean-k-mooney | or rather its addtional info that is included with nova queries placement | 15:51 |
| stephenfin | Darn, it all comes back to placement | 15:51 |
| *** armaan has quit IRC | 15:51 | |
| *** armaan has joined #openstack-nova | 15:51 | |
| sean-k-mooney | stephenfin: i did have a proposal to do this with a neutron api for network backend capablities in mitaka before placement but that never went anywhere outside intel | 15:52 |
| stephenfin | Yeah, so NUMA stuff. I naturally want to be able to do this stuff in the scheduler but I don't have enough information at that point to make a decision | 15:52 |
| *** openstackgerrit has joined #openstack-nova | 15:52 | |
| openstackgerrit | Matt Riedemann proposed openstack/nova master: doc: add a link in the install guides about configuring neutron https://review.openstack.org/559115 | 15:52 |
| stephenfin | I can figure out what network I have but then I need to map that network to a given NUMA node | 15:53 |
| *** sahid has quit IRC | 15:53 | |
| stephenfin | and that information lives on each individual host, either as a configuration option or something else | 15:53 |
| sean-k-mooney | stephenfin: well you can have enough info in the schduler if you populated it in the host state object. placement does not know about it however unlees the compute agent puts it in placement too | 15:53 |
| stephenfin | so it looks like I'm going to have to pass it back to the scheduler via the host state object, which I'm not sure I want to do | 15:54 |
| *** Swami has quit IRC | 15:54 | |
| stephenfin | sean-k-mooney: yup, exactly | 15:54 |
| *** damien_r has quit IRC | 15:54 | |

| sean-k-mooney | so the compute agent would read the config opptions and populated the numa info for the backend into the numatopology blob then the numa topology filter which gets that blob in the host_State object can make desions about the host | 15:55 |

| stephenfin | sean-k-mooney: Hmm, I hadn't considered that. I'd been adding additional fields and then got stuck because I had a network from the user and physnet name from the host | 15:57 |
| sean-k-mooney | stephenfin: your only other option bar modleing it in placement which is the long term answer is to not scheduler based on the numa constriats and retry if you cannont fit the insance on the compute node that was selected | 15:57 |
| stephenfin | *I had considered that but... | 15:57 |
| sean-k-mooney | stephenfin: well you have more then the network | 15:58 |
| sean-k-mooney | your stuff assumed that the vm was booted with a nuton port | 15:58 |

| *** tesseract has quit IRC | 15:59 | |
| *** tbachman has joined #openstack-nova | 15:59 | |
| sean-k-mooney | in that case we already pull back the full neutron port object to check if its an sriov port | 15:59 |
| sean-k-mooney | so you can ask neutron for the physnet and put that in the instance request object | 15:59 |
| sean-k-mooney | you can also determin if its a tunneled/routed port | 16:00 |
| stephenfin | sean-k-mooney: Yup, I've been charting that this afternoon :D http://paste.openstack.org/show/718499/ | 16:00 |

| *** tbachman has quit IRC | 16:03 | |
| sean-k-mooney | stephenfin: oh and i started rebasing rodoflos patches yesterday | 16:04 |
| stephenfin | Only, like I said, it seemed useless to me because I didn't want to be querying neutron for more information from the scheduler | 16:04 |
| sean-k-mooney | i hope to have them back up tomrowo or monday | 16:04 |
| stephenfin | sean-k-mooney: Sounds good. I can review once they're done | 16:04 |

| stephenfin | Try not to laugh too hard. It's strewn with TODOs :D | 16:05 |
| sean-k-mooney | well i broke them more in the refactor. once they are back passing unuit test i will need to do some more testing with real hardware so they wont be "ready" untill later next week but they can still be reviewed | 16:05 |
| stephenfin | Yeah, that's fine. I can do some basic validation too | 16:05 |
| stephenfin | ...given that I actually have hardware again | 16:06 |

| *** gjayavelu has joined #openstack-nova | 17:40 | |
| melwitt | tssurya: yeah ... the way cells v1 works is it will write the instance data to the API level DB first, then sync the instances table down to child cell, and I assume instance_extra must not be part of that | 17:41 |
| melwitt | so you'll never see instance_extra in child cells AFAIK | 17:42 |
| tssurya | yes , this is what we are also thinking | 17:42 |
| tssurya | I mean we have instance_extra, but some fields are not being synced | 17:42 |

| tssurya | yea | 17:43 |
| mriedem | jaypipes: dingers on that image meta props traits change | 17:43 |

| efried | jaypipes: Sorry, which statement/patch? | 18:04 |
| mriedem | arvindn051: if you want to handle the edge case check in a follow up that's fine with me | 18:05 |
| arvindn051 | jaypipes: thanks. i am just starting out with contributing to the project...so learning pains is how i am taking it. So close to getting it checked in :) | 18:05 |
| jaypipes | efried: "No, I think that, under the current design, if you want two VFs, you should specify them in separate granular request groups, even if they're identical, so that you'll still get a viable candidate in the scenario described for this test case." | 18:05 |
| mriedem | arvindn051: add the check on top and i'll approve this | 18:05 |
| *** dtantsur is now known as dtantsur|afk | 18:06 | |
| efried | jaypipes: We talked about that some more in IRC afterwards IIRC, and I gave up on the idea that we would separate out the *results* for that kind of request. But there's nothing contradictory there. Specifying two identical VFs in separate numbered request groups allows you to get viable results whether you have (available inventory in) one PF or multiple. | 18:07 |
| efried | jaypipes: I also realized later that we can't separate out the results without changing the response format, because dict. | 18:08 |
| *** pcaruana has joined #openstack-nova | 18:08 | |
| efried | jaypipes: So I accepted that, in such cases where placement had to combine those results, the caller would have to pick them apart again (based on their request, I guess). | 18:08 |
| efried | jaypipes: In any case, like I said in that comment, we're going to need both semantics at some point. It's just a matter of which one is the default. | 18:09 |

| jaypipes | While such a split could be seen to be sane for e.g. VFs, it is clearly not | 18:13 |

| efried | I'm sure I'm having trouble seeing it because I wrote it, but to me this is crystal: "Separate groups (numbered or un-numbered) may return results from the same RP. That is, you are not guaranteeing RP exclusivity by separating groups. (If you want to guarantee such exclusivity, you need to do it with traits.)" | 18:25 |
| jaypipes | efried: it's a subtle but extremely important distinction that "use_same_provider=True" meant (for you) that the resources from the single request group would be met by the same provider, which dansmith and I thought it meant that the resources in granular request groups would be met by different providers. | 18:25 |

| odyssey4me | Hi everyone. I wonder if someone could help just verify whether this is normal or not. I'm trying to use the openstack client to disable a service, but it errors out. This is on a test environment which was deployed with Pike, then upgraded to Queens. I've tried this with the scheduler, consoleauth and conductor services, all with the same result.: https://gist.github.com/odyssey4me/5cec9c69dcf0f118f7a62464df64b480#file-output-log-L74 | 18:26 |
| jaypipes | odyssey4me: hi Jesse, yes, that's normal. you need to reconcile your cell to host mappings. | 18:26 |
| efried | we're talking about the code now? (Cause use_same_provider isn't part of the spec.) There's no way use_same_provider=True could be construed (or even used) to signify anything *between* request groups. | 18:26 |
| jaypipes | efried: use_same_provider=False is set on numbered request groups. | 18:27 |
| jaypipes | efried: which makes it seem that resource providers will not be the same for each numbered request group. | 18:27 |
| odyssey4me | jaypipes apologies for my ignorance - what exactly does that mean? got a doc link or something for me? | 18:27 |
| efried | vice versa jaypipes | 18:27 |
| jaypipes | efried: I'm not saying you meant to cause this confusion, just that it obviously is confusing to some people. | 18:28 |
| efried | :param use_same_provider: | 18:28 |
| efried | If True, (the default) this RequestGroup represents requests for | 18:28 |
| efried | resources and traits which must be satisfied by a single resource | 18:28 |
| efried | provider. If False, represents a request for resources and traits | 18:28 |
| efried | in any resource provider in the same tree, or a sharing provider. | 18:28 |
| jaypipes | odyssey4me: yeah, sec, grabbing one | 18:28 |
| efried | To put it in context, though, a RequestGroup is *one* request group. This says nothing of how this RequestGroup interacts with other RequestGroups. | 18:28 |

| *** armaan has joined #openstack-nova | 18:32 | |
| mriedem | odyssey4me: the services API only allows enabling/disabling 'compute' services once you're on cells v2 | 18:32 |
| mriedem | b/c those compute service are mapped to a cell in the api db, but other non-compute services aren't | 18:32 |
| mriedem | plus, | 18:32 |
| mriedem | it doesn't make sense to disable non-compute services, as that doesn't mean/do anything | 18:32 |
| odyssey4me | ok, then something's probably wrong in our config or something - because this started life as pike, so cellsv2 should have just been there from the start | 18:33 |
| mriedem | odyssey4me: https://docs.openstack.org/releasenotes/nova/pike.html#id23 | 18:33 |
| mriedem | The PUT /os-services/disable, PUT /os-services/enable and PUT /os-services/force-down APIs to enable, disable, or force-down a service will now only work with nova-compute services. If you are using those APIs to try and disable a non-compute service, like nova-scheduler or nova-conductor, those APIs will result in a 404 response. | 18:33 |
| odyssey4me | oh doesn't it? I'm trying to do a nice process of disable, then shut down, then wipe the containers | 18:33 |
| mriedem | check that release note | 18:34 |
| odyssey4me | aha, I see | 18:34 |
| jaypipes | efried: could you please explain to me your comment on https://review.openstack.org/#/c/534339/ then? If I have a single compute node with 2 PFs with 2 SRIOV_NET_VFs, and I request 4 SRIOV_NET_VF, how exactly are you proposing that we determine that that compute node is a good match for the request? | 18:34 |
| odyssey4me | so I shouldn't be so nice and just wipe them :) | 18:34 |
| efried | jaypipes: stand by | 18:34 |
| odyssey4me | ok, many thanks - it makes much more sense now.. effectively it's no longer a thing, so don't do it | 18:35 |
| mriedem | odyssey4me: likely a relic of your upgrade tooling | 18:35 |
| mriedem | worked going from pre-cellsv2 to cellsv2, but not cellsv2+ | 18:35 |
| mriedem | and yeah, was never a use in disabling / enabling non-compute services | 18:36 |
| efried | jaypipes: I'm not sure which comment you're referring to, but to answer this: "If I have a single compute node with 2 PFs with 2 SRIOV_NET_VFs, and I request 4 SRIOV_NET_VF, how exactly are you proposing that we determine that that compute node is a good match for the request?" | 18:36 |
| efried | jaypipes: Without knowing beforehand whether the compute node has one PF or two or four, or how many VFs are available on any of them, the most flexible way to issue that request and have the highest chance of landing *somewhere* would be: resources1=VF:1&resources2=VF:1&resources3=VF:1&resources4=VF:1 | 18:38 |
| efried | that's of course assuming there are no traits in play (which in the case of PFs there likely would be, to represent nets or whatever) | 18:38 |

| jaypipes | efried: wow... | 18:42 |
| jaypipes | efried: and what about DISK_GB? if we don't get a single provider that has 1024 GB of disk space from a single disk, do we break the request into two requests for 512 MB from two different resource providers? | 18:42 |
| efried | not unless you want two disks. | 18:43 |
| jaypipes | efried: the resource is not a disk. The resource is DISK_GB. i.e. an amount of GB of disk space. | 18:43 |
| *** suresh12 has quit IRC | 18:43 | |
| efried | Right. Point is that the *caller* understands the semantics of that, though. Not placement. | 18:43 |
| *** suresh12 has joined #openstack-nova | 18:44 | |
| efried | So if you want two 512GB disks, you say resources1=DISK_GB:512&resources2=DISK_GB:512. They may come from the same provider (which will respond with DISK_GB:1024 and you'll have to go back to your request to figure out that you wanted to split it up) or they may come from separate providers. | 18:44 |
| *** liverpooler has joined #openstack-nova | 18:44 | |
| efried | It would be nice if the user didn't have to know that the systems in the cloud have one disk or ten, on PF or eight, etc. He just wants his instance to land. | 18:45 |
| efried | Or maybe that's wrong. Maybe there needs to be tight coupling between the flavors and the exact topology of the cloud. | 18:46 |
| efried | but that doesn't seem very... cloudy to me. | 18:46 |

| efried | okay: what's the real-world problem that demands separation? NUMA? | 18:47 |
| jaypipes | efried: I don't believe that there is a viable use case for a request for 4 SRIOV VFs and the requester doesn't care whether the VFs are provided by a single PF or two PFs. | 18:47 |
| *** pcaruana has quit IRC | 18:47 | |
| efried | FWIW, we implemented exactly that use case in powervm for SR-IOV. | 18:47 |

| efried | When there's only one PF available. | 18:49 |
| jaypipes | efried: if there's only one PF available, and the image/flavor needs >1 SRIOV VF, then IMHO, that compute node with only a single PF shouldn't be a legit destination node. | 18:50 |
| efried | jaypipes: If I don't care about HA, and I said resources1=SRIOV_NET_VF:1&required1=CUSTOM_PHYSNET_A&resources2=SRIOV_NET_VF:1&required2=CUSTOM_PHYSNET_B (because that's the only way I can get two VFs on separate physnets), and I was *forced* to use two separate PFs to make that happen, I would not be able to land an instance on a node with just one PF. | 18:50 |
| jaypipes | efried: the whole purpose of having multiple VFs is to allow active/failover for links... | 18:50 |
| efried | When HA is the issue, yes. | 18:50 |

| *** salv-orlando has quit IRC | 18:57 | |
| efried | Look, I'm (still) not arguing that there are cases where it will be useful to force split. I'm (still) asserting that we're going to need to be able to handle both. One behavior will be the default, and the other will require some extra syntax to make it happen. I'm not convinced we truly need *either* immediately. So I've been advocating for the default being the one that's in the spec, because that's the one that make | 18:58 |
| efried | head since Denver. But as I said here https://review.openstack.org/#/c/555081/4/specs/rocky/approved/cpu-resources.rst@412 I get that I'm being outvoted. So let's stop trying to convince each other that ours is the one true vision and just get on with making things happen. I'm implementing the granular algorithm right now. If you want to propose an amendment to the spec, let's git r done. | 18:58 |
| efried | (But on that note, I don't have a good way to tie separate request groups together unless allocation requests include the anchor provider.) | 18:59 |

| eandersson | mriedem, cfriesen_ thanks - yea was hoping to figure out when (resize, evacuate etc) was actually fixed | 19:34 |
| mriedem | eandersson: i'm not sure what about evac would be broken for instances with numa | 19:34 |
| mriedem | evac goes through the scheduler to find a new host and has to do a claim on that new host, just like normal server create | 19:34 |
| eandersson | Yea - it's possible we were mislead by this bug report https://bugs.launchpad.net/nova/+bug/1417667 | 19:34 |

| mriedem | that does look misleading, | 19:35 |
| mriedem | cfriesen_ reported that for live migration, and then it looks like a blanket statement was made about other operations, including rebuild, which isn't a move operation | 19:36 |
| *** liverpooler has quit IRC | 19:36 | |
| eandersson | We did do a lot of testing on this, but honestly don't remember what was actually broken (besides live migration) for us | 19:37 |

| eandersson | btw unrelated by is there a reason why filters and weights weren't made into plugins? | 19:40 |
| mriedem | so i think we can probably mark this as fixed for evac and cold migrate, and open a new bug for tracking the live migration issue, which is being resolved via https://specs.openstack.org/openstack/nova-specs/specs/rocky/approved/numa-aware-live-migration.html in rocky | 19:40 |

| *** yamamoto has quit IRC | 19:45 | |
| mriedem | ok so i think i was wrong about the plugin, | 19:47 |
| mriedem | i think that might just be the scheduler driver entrypoint | 19:47 |
| mriedem | https://github.com/openstack/nova/blob/master/nova/scheduler/filters/__init__.py#L64 | 19:48 |
| mriedem | loads up the filters from nova/scheduler/filters as you said | 19:48 |
| mriedem | https://docs.openstack.org/nova/latest/user/filter-scheduler.html#writing-your-own-filter doesn't mention that you have to drop them into the code tree | 19:48 |
| eandersson | It would be a nice feature, because someone might write a scheduler to automatically upgrade their computes | 19:49 |
| eandersson | you know sounds like a cool thing | 19:49 |
| melwitt | it used to be free-form pluggable but it locked down more recently, IIRC. and the doc not updated | 19:49 |
| eandersson | I see | 19:49 |
| mriedem | eandersson: typically nova is anti-plugin | 19:49 |
| mriedem | and have slowly evolved over time to cut out plugin points, as they aren't tested and we break them as such | 19:49 |
| mriedem | plus, interop is a concern with too many plug points | 19:50 |
| mriedem | for a private cloud that just wants to customize everything, interop isn't a concern, but it's a concern for public cloud | 19:50 |
| mriedem | well, could be a concern for private cloud if it ever wants to use the same APIs on a public cloud | 19:50 |
| melwitt | yeah, I've seen it bite private cloud when people used other open source tools that talk to openstack | 19:51 |
| melwitt | that expected the APIs to be a certain way | 19:51 |
| eandersson | Yea - makes sense | 19:53 |
| melwitt | they thought "oh I can use this tool to talk to the openstack private cloud" and something custom in the cloud API tripped it up so they couldn't use the tool | 19:53 |
| mriedem | i can't see anything in loadables or filters that used to use extension points | 19:54 |
| mriedem | looks like it's just always been classpath loading since 2012 | 19:54 |
| eandersson | Yea - the first place I always look is setup.cfg | 19:54 |

| mriedem | i think that was also killed in liberty | 19:57 |
| melwitt | right | 19:58 |
| eandersson | btw more crazy questions... why was a notifaction on instance rename never implemented? | 19:58 |
| mriedem | no one ever asked for/wrote it? | 19:58 |
| mriedem | there are notifications on instance.update | 19:59 |

| mriedem | http://git.openstack.org/cgit/openstack/nova/tree/nova/notifications/base.py#n121 | 20:00 |

| eandersson | cool - maybe I can add that to designate | 20:01 |
| eandersson | https://github.com/openstack/designate/blob/master/designate/notification_handler/nova.py#L73 | 20:01 |
| mriedem | hmm, i don't think the display_name is what you're looking for | 20:01 |
| mriedem | "host_name": "some-server", | 20:02 |
| mriedem | host_name is what's used for the DNS entry i think | 20:02 |
| eandersson | Yea - it is | 20:02 |
| melwitt | yeah and host_name is derived from the display_name during create | 20:02 |
| mriedem | and you can't change that via the REST API | 20:02 |
| *** sree has joined #openstack-nova | 20:02 | |
| mriedem | https://developer.openstack.org/api-ref/compute/#update-server | 20:03 |

| *** sree has quit IRC | 20:07 | |
| mriedem | if we updated the hostname that would also likely imply a rebuild needed to get it into the guest | 20:07 |
| melwitt | would this be a problem if anything in the exception message (like string substitutions like display_name) has unicode characters in it? https://review.openstack.org/#/c/555812/5/nova/exception.py@108 | 20:07 |
| mriedem | or at least a reboot | 20:07 |
| mriedem | melwitt: ah, yes, probably | 20:08 |
| melwitt | yeah. it would take some doing. I think people have asked for it before but not sure what all would be involved | 20:08 |

| mriedem | i see you guys are bff's | 20:09 |
| efried | mriedem: looking... | 20:09 |
| eandersson | I tested evacuate in mitaka and it failed :'( | 20:09 |
| melwitt | ruh roh | 20:10 |
| mriedem | eandersson: with an instance that has numa? | 20:10 |
| eandersson | Yea - I created 5 instances on two computes with numa pinning | 20:10 |
| mriedem | did it fail because of numa or because of something else? | 20:10 |
| efried | mriedem: Got him on slack. Whaddayaneed? | 20:10 |
| mriedem | efried: see the comment in https://review.openstack.org/#/c/555812/ about unicode | 20:11 |
| eandersson | and evacuated two of them to the other compute, and the two evacuated now have conflicting numa pinning | 20:11 |
| mriedem | eandersson: did you evacuate them at the same time? | 20:11 |
| eandersson | Yes | 20:11 |
| mriedem | well, | 20:11 |
| mriedem | that's your problem :) | 20:11 |
| efried | mriedem: Ack. But... I thought they fixed that issue down at the oslo.log level. | 20:11 |
| eandersson | So the two vms are not conflicting with each other | 20:11 |
| mriedem | eandersson: the numa resource claim happens on the compute service, not in the scheduler, so you're racing with concurrent evac requests to claim the same thing | 20:12 |
| eandersson | they both kept their pinnings | 20:12 |
| efried | mriedem: Hum, that totally wouldn't help here, huh? | 20:12 |
| mriedem | efried: no | 20:12 |
| eandersson | they are conflicting with vms that already were on the compute | 20:12 |
| mriedem | eandersson: hmm | 20:12 |
| mriedem | eandersson: the evac should fail then shouldn't it? | 20:12 |
| *** arvindn051 has quit IRC | 20:13 | |
| mriedem | if the resources are already taken by other VMs on that host | 20:13 |
| eandersson | Yea - I just don't think it knows that it is conflicting | 20:13 |
| eandersson | because it's technically not "invalid" to pin two vms on the same cores | 20:13 |
| mriedem | what is valid or not with the numa stuff at this level is over my head, and would require the likes of cfriesen_, stephenfin, jaypipes, et al | 20:14 |
| eandersson | Yea - hoenstly I bet this is fixed in newer versions | 20:14 |
| eandersson | We just need to upgrade | 20:14 |
| mriedem | hopefully you're not too heavily forked | 20:14 |
| eandersson | nah - it's more cells etc | 20:14 |
| mriedem | upgrading to cells v2 never hurt *anybody* | 20:15 |
| eandersson | it's a big jump, or feels like one at least :D | 20:15 |
| melwitt | yeah. no one has ever complained about it | 20:15 |
| eandersson | How does nova perform now with... a lot of computes? | 20:15 |

| owalsh | not had time to look into it though | 20:29 |
| efried | mriedem, melwitt: tblakes has acked internally and will get on that fup. | 20:30 |
| melwitt | owalsh: by transport_url handling do you mean trying to use both the transport_url config option and the legacy options at the same time? or using only legacy options the resultant transport_url was wrong? | 20:30 |
| owalsh | melwitt: using both transport_url and the legacy options at the same time | 20:31 |
| owalsh | melwitt: I'll mention it on the LP at least | 20:31 |
| melwitt | owalsh: yeah, I'm pretty sure that won't work because one (transport_url) is a superset of the others. like, if transport_url is set, that will be taken and nothing else considered. I'm not 100% sure though | 20:31 |
