| gilliard | jogo: What was the test which was failing frequently on the multinode job? | 09:35 |

| jogo | that is the good news | 09:54 |
| *** fesp has quit IRC | 09:55 | |
| jogo | and this is the offending patch: https://review.openstack.org/#/c/177437/ | 09:56 |
| *** dims has quit IRC | 09:56 | |
| gilliard | I have 2 questions. 1/ how do you know it's 100% breakage? I really struggle to get that kind of info out of logstash | 09:57 |
| *** park_heijlong has quit IRC | 09:57 | |
| gilliard | 2/ How did you find that patch so fast?! | 09:57 |
| jogo | gilliard: great questions. | 09:58 |
| jogo | 1) with this query message:"Finished: SUCCESS" AND build_name:"check-tempest-dsvm-multinode-full" | 09:58 |
| jogo | so that will show you the last time multinode finished successfully | 09:58 |
| jogo | first hint that it was 100% failure was my graphite page http://jogo.github.io/gate/multinode.html | 09:59 |
| jogo | that is a very steep curve (moving average) | 09:59 |
| jogo | 2) I went into n-cpu and looked for stacktraces | 09:59 |
| jogo | http://logs.openstack.org/92/139992/31/check/check-tempest-dsvm-multinode-full/59bcd9b/logs/screen-n-cpu.txt.gz?level=TRACE | 09:59 |
| jogo | and found this fingerprint: message:"TypeError: string indices must be integers" AND tags:"screen-n-cpu.txt" | 09:59 |
| jogo | then looked for the first few hits for it | 10:00 |
| garyk | BobBall: any idea why citrix CI is broken - can we stop the -1 vote until it is fixed. My world is red (and I am not a liverpool fan) | 10:00 |
| jogo | the first hits are from two separate runs on the same patch | 10:00 |
| jogo | (build_change in logstash) | 10:00 |
| BobBall | I've already turnd it off | 10:01 |
| BobBall | no idea what's going on though | 10:01 |
| BobBall | trying to investigate | 10:01 |
| BobBall | Just one more job running that'll get a -1 vote (189576) - but no more -1s will be posted | 10:01 |
| BobBall | Don't suppose you've got an idea why requests might disappear? http://dd6b71949550285df7dc-dda4e480e005aaa13ec303551d2d8155.r49.cf1.rackcdn.com/63/190063/1/581/logs/devstacklog.txt.gz | 10:02 |
| jogo | gilliard: it would be great of you try what I just did and hopefully come to the same conclusion | 10:02 |

| lpetrut | jogo: Hi. We'd like to add support for nova assisted volume snapshots using a similar workflow as the one used by the Libvirt driver. Considering the fact that this is a parity feature, would it require a spec or is a blueprint enough? | 10:51 |
| lpetrut | jogo: this is targeting the Hyper-V driver | 10:51 |
| jogo | lpetrut: not sure, a blueprint at the very least. You can add the blueprint to the next nova meeting schedule to see if needs a spec or not | 10:52 |

| *** ildikov_ has joined #openstack-nova | 12:46 | |
| jogo | kashyap: yes, but not sure if neutron is stable enough even for that | 12:46 |
| jogo | my hunch is the two bugs we are seeing are nova-net related | 12:47 |
| jogo | so if you test neutron you will hit a separate class of bugs (ones that need fixing as well) | 12:47 |
| kashyap | Yep, noted. The thing is, I hardly ever ran nova-net, just so that I can get used to debugging OVS w/ Neutron. | 12:47 |
| jogo | kashyap: well if you want to work on getting the neutron version of the job working, by all means go for it | 12:48 |
| jogo | it uses DVR in neutron AFAIK | 12:48 |
| jogo | and I don't remember of the top of my head who is working on it over there | 12:48 |
| kashyap | jogo: Prefer to begin with small steps. Not sure if this DVR thing _necessary_. I'd begin with a simple OVS+GRE/VXLAN env - that's complex enough. | 12:49 |
| jogo | kashyap: you should talk to the neutron team and see who is working on it over there | 12:50 |

| jlanoux | jogo: you can always harass qa cores to review and approve the changes :) | 13:13 |
| mriedem | danpb: i figured out why we weren't getting volume encryption metadata back from cinder for the ceph case - it's pretty simple actually, | 13:14 |
| *** otter768 has joined #openstack-nova | 13:15 | |
| mriedem | danpb: nagyz: the problem is the rbd volume driver in cinder doesn't set the 'encrypted' key in the connection_info sent back during initialize_connection like the isci volume driver does | 13:15 |
| *** ajayaa has quit IRC | 13:15 | |
| mriedem | that's the flag that nova is checking before calling the cinder API | 13:15 |
| *** mdrabe has joined #openstack-nova | 13:15 | |
| mriedem | so while i could 'fix' that in cinder, there are many volume drivers that don't set it and i'm not sure if that's on purpose or not - the cinder API shows if a volume is encrypted or not | 13:15 |
| mriedem | my guess is this is some leftover tight coupling from when the volume service was in nova, but that was before my time | 13:16 |

| danpb | mriedem: merely setting the encrypted flag isn't going to do anything useful though | 13:20 |
| danpb | because nova will not have any way of supporting encryption with rbd | 13:21 |
| *** tojuvone has joined #openstack-nova | 13:21 | |

| mriedem | and confirmed that it blows up https://review.openstack.org/#/c/190053/ | 13:21 |
| danpb | i think it is really serious bug that you can request encryption via an api call and have that request totally ignored | 13:21 |
| mriedem | in cinder? | 13:22 |
| danpb | we really must return an error to the user if they request something that cannot be honoured | 13:22 |

| *** yingjun has quit IRC | 13:23 | |
| mriedem | danpb: it's almost like the cinder volume drivers need capabilities bubbled up to the volume manager to tell it if they support encryption, like what we do with the virt drivers | 13:23 |
| mriedem | then if a request is made to create a volume from an encrypted volume type, if the driver doesn't support it it should blow up | 13:23 |
| mriedem | i also poked around in the connection_info bits in some of the various cinder drivers, and oh those are not fun if we want to try and model some of that with objects in nova | 13:24 |
| *** ociuhandu has joined #openstack-nova | 13:25 | |
| mriedem | plus those are not considered any part of the cinder API, it's just a black box and you get what the vendor driver gives you, and you'd better hope it doesn't change | 13:25 |
| danpb | mriedem: yeah, thta's exactly why we must model them as objects - this free-for-all cannot continue | 13:25 |
| asselin_ | is this wiki page spec implemented? I couldn't find any docs on it. https://wiki.openstack.org/wiki/Spec-provider-firewall | 13:26 |
| danpb | we'll hopefully have the VIF stuff modelled as objects soon too | 13:26 |
| mriedem | i think i'm going to start by just trying to document the connection_info that comes back from the cinder drivers to get an idea for what's common | 13:26 |
| danpb | mriedem: yeah, that's a good idea | 13:26 |

| nagyz | mriedem, I was thinking to reuse the iSCSI device mapping code that I'm sure happens for iSCSI volumes at the moment? | 13:35 |
| nagyz | that's already in tree | 13:35 |
| mriedem | BobBall: gross, looks like this also needs to be backported to at least kilo and maybe juno? | 13:35 |
| danpb | if you wanted todo that, you'd really need to make cinder return a connection_info with the iscsi driver type, instead of rbd type | 13:35 |
| danpb | but that seems like the wrong way to go | 13:35 |
| danpb | instead I think you'd want to use the rbd kernel module so that the compute host makes a direct connection to the rbd server | 13:36 |
| *** rotbeard has quit IRC | 13:36 | |

| BobBall | No - I assumed once alaski figured out what was going on that it was recently introduced | 13:37 |
| nagyz | danpb, based on the data returned from cinder we should be able to distinguish between an iSCSI and an rbd connection, right? so we can handle it per-case | 13:37 |
| mriedem | BobBall: maybe doesn't matter, the code in the bw usage object is wrong, and it goes back to juno so probably needs to be backported either way | 13:37 |
| danpb | the cryptsetup part of nova is all in nova/volume/encryptors | 13:38 |
| *** oro has quit IRC | 13:38 | |
| alaski | BobBall: mriedem it was introduced when the bw usage task moved to objects | 13:38 |
| BobBall | Perhaps, but it does raise the question of if actually this is just a symptom rather than the real issue... Which might mean it might not fix the race we're hitting | 13:38 |

| nagyz | danpb, so do you think that in the cryptsetup part let's check the driver_volume_type and if it's rbd then do the kernel mapping? I haven't looked at the code there but there must be a similar code path already for iSCSI in place, right? | 13:43 |

| mriedem | i didn't really want our object to be made up of 2 fields: driver_volume_type (string) and data (dict of strings) | 13:59 |
| mriedem | honestly cinder should really have an object modeling that on their side that is versioned and the volume drivers should be using it, and if someone adds/drops/renames a field it would bump the version | 14:00 |
| mriedem | and the caller (nova) would have the version for compat handling | 14:00 |
| mriedem | like actually store the version of the connection_info object in cinder and return that in os-initialize_connection | 14:01 |

| danpb | mriedem: indeed - this is the case where we'd define a ConnectionInfo base object, and then subclass it for RBDConnectionInfo, ISCSIConnectionInfo, etc and have everything formally specified | 14:08 |
| danpb | some static method on ConnectInfo would look at driver_volume_type to decide which subclass to instantiate perhaps | 14:08 |

| johnthetubaguy | jroll: we have notes in the etherpad, linked from the wiki, but I think we need a nova spec for the nova work, we could probably merge something in the docs around the longer term vision, but I don't have the structure in place for that yet I am afraid | 14:09 |
| alex_xu | dansmith: hi, good morning. I read you talk with cfriesen about cpu model yesterday. As my understand you prefer an API can be used to define what cpu model and what cpu features in that model. Then scheduler choice one host can support that model and those features. Then compute-node build up an instance with that model and those features. | 14:10 |
| alex_xu | However our propose is reversed with your propose. We propose nova-compute report supported cpu models and features in those models. Then user choice one of it to boot up that instance. Did I understand right? | 14:11 |
| *** abhishekk has quit IRC | 14:11 | |
| BobBall | danpb: Thanks for the second review (https://review.openstack.org/#/c/189397/); Just checking - are you happy to +A or do you think it needs more eyes? (I suspect you and mriedem reviewed in parallel) | 14:11 |
| mriedem | danpb: i'm writing up some ideas on that to the ML now for cinder devs - and i'm going to be bugging jungleboyj about this when he gets into the office since he can't physically hide from me | 14:11 |
| danpb | BobBall: ah yes | 14:11 |
| BobBall | Joy of joys! | 14:12 |
| BobBall | Thanks. | 14:12 |
| dansmith | alex_xu: yes, but the problem is not that the models are sourced from the compute, the problem is that the models reported from the compute are not consistent because hypervisor versions, technologies, etc will report different things under the same name | 14:12 |
| *** aloga has quit IRC | 14:13 | |
| alex_xu | dansmith: ok, I see now, your propose force all hypervisor create instance with the specific model and features. Then resolve all the problem created by inconsistent between hyperivsors, even different version hyepervisors | 14:14 |
| *** dguitarbite has joined #openstack-nova | 14:14 | |
| dansmith | alex_xu: yes | 14:14 |
| *** aloga has joined #openstack-nova | 14:15 | |
| dansmith | alex_xu: you can report flags up so the scheduler can place what was requested, but you have to do that by flags and not by the arbitrary model name | 14:15 |
| alex_xu | dansmith: ah, thanks, I see now:) and the API you expected is jaypipes proposed resource template? | 14:15 |
| dansmith | alex_xu: no, I don't think jaypipes has proposed the flavors/options spec yet, AFAIK | 14:15 |
| danpb | dansmith: using flags exclusively only works on x86 | 14:15 |
| *** pilgrimstack has quit IRC | 14:16 | |
| danpb | dansmith: non-x86 architectures don't really have the same fine grained CPUID flags concept | 14:16 |
| danpb | dansmith: so for those the only option is using cpu model names | 14:16 |
| *** VW has quit IRC | 14:16 | |
| danpb | if we want to expose the ability to influence placement based on cpu, I'm not sure i see any solution which is portable across hypervisors | 14:17 |
| dansmith | danpb: we could report flags that correspond to architectures from the compute when we're on such a platform, right? like ppc64native or whatever | 14:17 |

| *** jecarey has joined #openstack-nova | 14:18 | |
| danpb | i guess you could introduce an abstraction so that only the cloud admin needs to care about hypervisor specific cpu differences | 14:19 |
| dansmith | danpb: you meant that on PPC we only have the machine type, right? | 14:19 |
| *** thangp has joined #openstack-nova | 14:19 | |

| jroll | johnthetubaguy: found it, ty | 14:19 |
| dansmith | the -M flag to qemu I mean | 14:19 |
| danpb | dansmith: no, i meant that on PPC you have a huge choice of cpus http://paste.fedoraproject.org/230740/14339459 | 14:19 |
| dansmith | danpb: right, so expose that machine type as a flag | 14:20 |
| danpb | and you can't express preferences based on CPU feature names | 14:20 |
| *** mpaolino has joined #openstack-nova | 14:20 | |
| dansmith | danpb: on intel you may ask for sse4 | 14:20 |
| danpb | that's not a machine type - that's cpu model names | 14:20 |
| dansmith | danpb: on ppc you may ask for 970mp | 14:20 |
| *** amotoki has quit IRC | 14:20 | |
| dansmith | fine, whatever, they're just symbols that the compute node exposes as capabilities | 14:20 |
| *** amotoki has joined #openstack-nova | 14:20 | |
| danpb | those aren't standardized across hyprevisors in any way | 14:20 |
| danpb | so we still have the same problem | 14:21 |
| *** mtanino has joined #openstack-nova | 14:21 | |
| dansmith | we have many fewer hypervisors that can do non-intel architectures, | 14:21 |
| danpb | i could see one way to solve this is to not expose any concept of cpu models and features to the tenant user at all | 14:22 |
| dansmith | and those that do are massively limited in the CPUs they could expose I think, so just standardizing those model names seems like a reasonable thing for us to do internally to nova | 14:22 |
| danpb | instead create a "CPU" object abstraction that the users choose | 14:22 |
| danpb | and let the cloud admin populate those abstractions with the hypervisor specific cpu model names / features | 14:22 |
| danpb | so the user would see & choose "Xeon with SSE3" | 14:22 |
| dansmith | danpb: we still need a way for them to control how to find a cpu like that, but yes that's the heavier approach I'd really like us to take | 14:23 |
| danpb | and the cloud admin would have setup a mapping so that uses CPUBlah on libvirt and CPUFoo on vmware | 14:23 |
| dansmith | danpb: doing it just based on flags is a medium approach between that and just cheaping out and using the model names the hypervisors provide | 14:23 |
| danpb | so the cloud admin still gets the pain of dealing with hypervisor specific setup | 14:23 |
| danpb | but the tenant user is isolated from it | 14:23 |
| *** READ10 has quit IRC | 14:23 | |
| dansmith | yes, this is what I originally asked for in the summit conversation | 14:23 |
| dansmith | although I think it needs to be modeled in a generic way, like what jaypipes was suggesting as options that sit on top of a flavor | 14:24 |
| dansmith | but yes | 14:24 |
| danpb | a much bigger bit of work, but it feels like the right approach if we want to islate the user from low level details | 14:24 |
| dansmith | yep | 14:24 |

| alex_xu | dansmith: yea, got that | 14:31 |
| *** yingjun has joined #openstack-nova | 14:32 | |
| *** arnaud____ has quit IRC | 14:32 | |
| alex_xu | dansmith: so user can use that API specific an fake model name like "Xeon with SSE3" and that includes a set of features. | 14:33 |
| dansmith | alex_xu: yes, but the model has to expose useful information I think, | 14:33 |
| dansmith | so it still needs to expose CPUID flags in the intel case, IMHO | 14:33 |
| dansmith | so that you can actually know what is included in that model | 14:33 |
| dansmith | "Xeon with SSE3" might be missing some other flag like vmx which is masked out | 14:34 |
| alex_xu | dansmith: yea, but what about the real cpu model used for guest? Like libvirt don't know "Xeon with SSE3", how hypervisor decide which real model used for guest? | 14:34 |
| dansmith | alex_xu: sure, you still have to turn that into something useful | 14:37 |

| dansmith | alex_xu: I don't think this will affect the existing libvirt mechanisms and restrictions | 14:40 |

| *** dguitarbite has joined #openstack-nova | 14:59 | |

| mriedem | *cinder | 14:59 |
| *** afazekas has quit IRC | 14:59 | |
| nagyz | mriedem, I think the current grouping is fine it's just confusing to have a generic net driver that has rbd and iscsi bits while there is a separate iscsi implementation there | 14:59 |
| nagyz | are you against introducing a separate RBDVolumeDriver that can be told if it's an encrypted volume or not and if it's non-encrypted it just calls the base method and if it is then it does the local attach/detach? | 15:00 |

| mriedem | ndipanov: danpb: why is it that the connection_info for NFS backends in cinder have a 'mount_point_base' but in the nova libvirt volume module for NFS volumes we also use our own config options, e.g. nfs_mount_point_base, glusterfs_mount_point_base, etc - couldn't we just get that info from cinder after initializing the connection? | 15:07 |

| lxsli | jaypipes: so in your patches I see IntegerAmount and IntegerUsage. That means that from one of those, there's no way to know what resource it applies to. We could use a dict with key ResourceType and value *Amount; but ugh. Do you think we need something (other than the computenode) to relate these?

| bauzas | jaypipes: hold the trigger for the RequestSpec series, I'm just now struggling with those lovely numa and pci hacks | 15:40 |
| nagyz | mriedem, so I see that the volume drivers are passingin a is_block_dev value to their superclass - now in the RBD driver we would need to handle this based on weather it's used for encryption or not | 15:40 |

| nagyz | mriedem, we could introduce a config flag that sets if it's if we want to use krdb or qemu for rbd mounting, but the nicer thing to do would be to use qemu's rbd for native and krdb for encrypted... however, introducing an LibvirtEncryptedRBDVolumeDriver sounds horrible | 15:43 |

| danpb | dansmith: this patch doesn't do anything to terminate live migration - it only cares about increasing the downtime value | 15:44 |
| dansmith | danpb: okay, so this makes it much better but we could still end up at the end of the steps with a migration that never completes, right? | 15:44 |
| danpb | dansmith: the second patch in the series introduces the concept of a overall timeout, along with detection & abort of stuck migrations (ie data is being dirtied faster than it is transferred) | 15:44 |

| dansmith | mriedem: so, I think mount options need not be a dict, but I don't know the details | 16:17 |
| dansmith | mriedem: what about the tgt_port_wwns? that has to be a dict? | 16:17 |
| *** mdrabe has joined #openstack-nova | 16:17 | |
| dansmith | because otherwise, all of that looks like it could easily be in the extra dict | 16:17 |
| rmk | dansmith: I shed a tear that you remember my coding days :D | 16:18 |
| mriedem | dansmith: i was just looking at how it's modeled in the cinder code today | 16:18 |
| lxsli | jaypipes: amounts can be negative. Is it still necessary to have a 'sign' argument to some methods or is that just confusing? | 16:18 |
| rmk | I just glanced at this for a second and I already know where this approach came from. | 16:18 |
| dansmith | rmk: well, still figure you can evaluate the usefulness or applicability of the config options being added | 16:18 |
| rmk | This is exactly what Proxmox does. | 16:18 |
| dansmith | rmk: even if you are too big of a deal to concern yourself with code these days :) | 16:19 |
| rmk | dansmith: Oh trust me I'd rather do this, they don't let me, not that I take myself too seriously. | 16:19 |
| rmk | I'm overhead now. | 16:19 |
| dansmith | heh | 16:19 |
| mriedem | mount options is probably not a dict, i got confused by the cinder code. tgt_port_wwns is a list | 16:19 |
| dansmith | mriedem: okay, lists are easily encoded in a string without much danger I think | 16:19 |
| rmk | OK this is going to require a new/current libvirt. | 16:20 |
| dansmith | is it? | 16:20 |
| dansmith | I guess I thought this had been available in libvirt for some time | 16:21 |
| rmk | It was broken. | 16:21 |
| dansmith | okay | 16:21 |
| rmk | We actually submitted the patch into Libvirt to fix it. Sometime in the 1.2.8+ timeframe. | 16:21 |
| mriedem | dansmith: fwiw i think everything could live in a single object with a bunch of optional fields | 16:22 |
| mriedem | dansmith: the downside of that is from a developer point of view things aren't typed very well | 16:22 |
| dansmith | mriedem: meaning real fields and not just a bag of extra as a dict? | 16:22 |
| mriedem | dansmith: yeah | 16:22 |
| dansmith | yeah, that gets more confusing I think | 16:23 |
| dansmith | because you have options that look formal but don't matter for a given backend | 16:23 |
| dansmith | mriedem: so does that mean you're leaning towards subclasses? let me answer your question above: | 16:23 |
| rmk | Basically libvirt would only allow setting maxdowntime while the domain was migrating. Well, two problems with that: the migrate libvirt call is a blocking operation, and then if you tried to set it during migration via libvirt, it would respond back that qemu monitor was unresponsive. | 16:23 |
| mriedem | dansmith: at a min we could have a single object with a few attributes like what connection_info is today, driver_volume_type, serial and 'data' | 16:23 |
| mriedem | where 'data' is a big dict of gorp | 16:23 |
| dansmith | mriedem: you can tie the versions of all of those objects together so that they all bump when anything bumps, which makes it a little easier | 16:23 |
| rmk | The limitation around setting maxdowntime only during migration isn't a reality for qemu itself, libvirt was imposing a limitation that didn't exist. | 16:23 |
| mriedem | but i don't want that b/c data has passwords in it and i want to specifically list those separately so we can mask them in the logs | 16:23 |
| dansmith | mriedem: yeah | 16:24 |
| *** teju has left #openstack-nova | 16:24 | |
| mriedem | i want to flatten the nested data dict out as much as possible so that the only thing left in 'data' from today is the vendor-specific thingies | 16:24 |
| rmk | I have to read more of this code but I don't see how this works. I'm sure danbp sorted it but I'd think this all needs to run in a thread of its own. | 16:24 |
| dansmith | rmk: thanks for justifying me pinging you for review :) | 16:25 |
| rmk | Haha np | 16:25 |
| mriedem | dansmith: so if the fibrechannel object version changes, we'd also bump the version in the shared object? | 16:25 |
| *** varya has quit IRC | 16:25 | |
| dansmith | mriedem: yeah | 16:25 |
| mriedem | that seems weird | 16:25 |
| *** vilobhmm has joined #openstack-nova | 16:25 | |
| dansmith | mriedem: doing that means we can automate some of the dependency stuff and make it less manually intensive when we need to tweak things | 16:26 |
| dansmith | mriedem: actually, you have this as inheriting from the same class, not a nested object relationship | 16:26 |
| *** mpaolino has joined #openstack-nova | 16:26 | |
| dansmith | mriedem: so it's a little less of a problem that way I think | 16:27 |
| dansmith | mriedem: the painful part comes in when one object embeds another, and the embedded object version changes, the parent has to be bumped as well to signal the change, and so that we can efficiently backport the whole thing and not just the leaves as we hit them | 16:27 |
| mriedem | dansmith: right, no nested objects right now | 16:27 |
| dansmith | yeah, we've not done it that way as often, usually because we don't have this sort of arrangement | 16:28 |
| mriedem | i originally thought we'd have a Data object that was nested within ConnectionInfo to model like how it is serialized today, but then i realized the way it is today sucks | 16:28 |
| dansmith | so yeah, I say give it a go | 16:28 |

| *** unicell has joined #openstack-nova | 16:39 | |
| mingy | specifically for example, there are test files in two different directories that test functions in nova/scheduler/filters/utils.py | 16:40 |
| mriedem | mingy: one is probably just older than the other | 16:40 |
| mriedem | mingy: like nova.tests.unit.compute.test_compute is old, and newer tests for the compute manager are in nova.tests.unit.compute.test_compute_mgr (mock compute.api), and test_compute_api (mock compute.manager) | 16:41 |
| openstackgerrit | Philip Marc Schwartz proposed openstack/nova: Implement online schema migrations https://review.openstack.org/154521 | 16:41 |
| mingy | mriedem: oh, what's the rationale for organizing it that way? | 16:42 |
| mriedem | mingy: for the compute manager tests? | 16:42 |
| mriedem | layer isolation | 16:42 |
| mriedem | so we can mock out the things that we aren't testing | 16:42 |
| mriedem | if i'm testing nova.compute.api, i hit that in test_compute_api and mock out the calls to conductor | 16:42 |
| mriedem | test_compute (old way) doesn't mock that stuff out, so requests go through comptue.api then through conductor and into compute.manager | 16:43 |
| mriedem | which is more of a functional test | 16:43 |
| *** tonytan4ever has joined #openstack-nova | 16:43 | |

| edleafe | mingy: there are also 2 utils files: nova/scheduler/utils and nova/scheduler/filters/utils | 17:10 |
| patrickeast | i’m having some trouble with nova-network dhcp in multi-host flat dhcp configuration, i have force_dhcp_release=True and see when instances are terminated that nova-network is calling the dhcp_release script (and its returning 0), but in nova-dhcpbridge.log i only sometimes actually see a ‘del’ | 17:10 |
| patrickeast | and then later if another vm is assigned the old ip address, the dnsmasq proccess gives error output in syslog saying the address is already leased to another mac address (the old vm that had been terminated) | 17:10 |
| ndipanov | jaypipes, many thanks | 17:10 |

| edleafe | mingy: yeah, just pointing out even more potential confusion | 17:16 |
| alaski | cfriesen: I can't say for sure for Rackspace, but I don't think it's anything we do intentionally | 17:16 |
| alaski | cfriesen: different versions of hypervisors would be my guess | 17:16 |
| edleafe | mingy: this might be a good place to start contributing: sorting this out and making the structure saner. | 17:16 |
| alaski | I've never investigated though | 17:16 |

| cfriesen | alaski: thanks. Dan mentioned the hypervisor version thing in a different context..my mind is blown that they would change the model/feature mapping after a model has been released. | 17:17 |

| johnthetubaguy | cfriesen: the old gear is AMD, the new stuff is Intel | 17:21 |
| johnthetubaguy | cfriesen: mostly we don't do any CPU masking, except a few cases where I think we needed some for live-migrate | 17:22 |
| johnthetubaguy | cfriesen: Xen CPU masking required a reboot, so its quite minimal | 17:22 |
| *** esmute has joined #openstack-nova | 17:22 | |
| johnthetubaguy | its possible Xen just hides some stuff when using its crazy QEMU fork, which causes extra confusion, but thats beyond where I have looked | 17:22 |
| *** annashen has joined #openstack-nova | 17:23 | |
| johnthetubaguy | cfriesen: I think as we get new hardware, some of them get new CPUs too, and to alaski's point, different version of Xen might give us some differences, but I didn't think they were massive, we have a few versions out there | 17:24 |
| *** pradipta has quit IRC | 17:24 | |

| johnthetubaguy | cfriesen: appreciate the effort to get a good solution thats workable across clouds | 17:26 |
| johnthetubaguy | cfriesen: its the CPU masking for live-migrate that means the models anyone expose might not actually be something anyone has ever made | 17:26 |
| danpb | cfriesen: fyi, intel have issued microcode updates in the past which removed features | 17:27 |
| cfriesen | johnthetubaguy: it's a pain in the butt. :) So it's starting to look like we're going to have to rely on the admin to come up with a hypervisor-specific "base_model+features" that gets exported as some sort of named entity for end-users to use. | 17:28 |
| danpb | this caused an unbelievable amount of pain because peoples guests configured to use those featurs no longer booted :-( | 17:28 |
| cfriesen | danpb: the haswell tsx stuff? or were there others like that? | 17:28 |

| johnthetubaguy | what happened with haswell? | 17:28 |
| johnthetubaguy | people want it I guess? | 17:29 |
| danpb | they screwed up the impl of a feature in silicon and had to disble it | 17:29 |
| cfriesen | johnthetubaguy: Intel realized the TSX instructions were broken | 17:29 |
| johnthetubaguy | oh... | 17:29 |
| *** claudiub has quit IRC | 17:29 | |
| johnthetubaguy | ooops | 17:29 |
| danpb | it also turns out they actually shipped cpus with the same names but without the feature present at all | 17:29 |
| johnthetubaguy | like the old floating point bug or something, that happened before | 17:29 |
| danpb | ie, you could actually buy haswell cpus which never had tsx in the first place | 17:29 |

| danpb | johnthetubaguy: nope, that doesn't work on non-x86 | 17:30 |

| *** esmute has joined #openstack-nova | 17:31 | |
| *** sdake has quit IRC | 17:31 | |
| danpb | primarily yes - fine grained cpuid like features are only used/exposed on x86 currently | 17:31 |
| cfriesen | danpb: so based on your comment it seems like we're going to need to let admins specify "base_mode+features" for the "high level model"? (In which case it'd be up to the admins to ensure that what they come up with will actually run?) | 17:31 |
| danpb | this is why libvirt tries very hard to discourage you from using features at all and focus on cpu model names | 17:32 |
| cfriesen | s/base_mode/base_model | 17:32 |
| johnthetubaguy | danpb: that makes sense now... ouch | 17:32 |
| danpb | well i'd expect admins would mostly just specify a base libvirt model - i doubt they'd often customize feature set | 17:32 |

| *** earlephilhower has joined #openstack-nova | 17:33 | |
| *** achanda has joined #openstack-nova | 17:33 | |
| danpb | for vmware i think you need to specify the raw cpuid hex masks | 17:33 |
| danpb | and likewise for xenapi iirc | 17:33 |
| cfriesen | danpb: dansmith was opinionated about wanting to be able to define something that would be common across hypervisors...that seemed to imply the ability to tweak features | 17:34 |
| danpb | we could possibly provide some canned cpu models in nova, so admin doesn't have to figure this out in a plain deployment | 17:34 |
| danpb | we could provide a tool which takes the libvirt cpu xml definitions and generates the suitable cpuid masks for xen & vmware to make their life easier | 17:35 |
| cfriesen | danpb: otherwise if we're not going to tweak features then it's basically my current proposal where you just use the CPU models actually present on hosts in the cloud. | 17:35 |

| mriedem | nagyz: i very much doubt it | 17:56 |
| mriedem | nagyz: it's pretty simple to trace though from the nova.compute.manager.attach_volume method | 17:57 |
| nagyz | ok, will do just that | 17:57 |
| mriedem | the nova.virt.block_device.attach method does the encryptor lookup stuff | 17:57 |
| mriedem | the do_driver_attach flag tells block_device to call the attach_volume method on the virt driver (libvirt) | 17:57 |
| mriedem | and that uses the encryptor (if present) to do the stuff in nova.volume.encryptors | 17:58 |

| openstackgerrit | Davanum Srinivas (dims) proposed openstack/nova: [WIP] cleanup openstack-common.conf and sync updated files https://review.openstack.org/189118 | 18:01 |
| mriedem | then that gets persisted in the block_device_mapping table in the nova db | 18:01 |
| *** harlowja has joined #openstack-nova | 18:02 | |
| mriedem | well, saved in the db after calling the virt driver | 18:02 |
| *** annegentle has quit IRC | 18:02 | |
| mriedem | once we get back from the virt driver's attach_volume, we call the attach API in cinder to mark the volume as in-use | 18:03 |
| mriedem | nagyz: maybe you want to throw a nice flow diagram into the devref after all :) | 18:03 |
| nagyz | :D | 18:04 |
| nagyz | I appreciate your help; I need to take care of some stuff but will dig into this later tonight and tomorrow and then push some patches for review... it can't be that hard :-) | 18:04 |
| mriedem | i think the compute api actually tells cinder to mark the volume as attaching before we even get to the compute manager in case of races | 18:05 |
| mriedem | and on failure that's rolled back | 18:05 |

| mriedem | like with v2.4 the os-fixed-ips response will have a 'reserved' field in it | 18:15 |
| melwitt | mriedem: not yet. some patches have been up for a long time but Im not sure if they do all the things needed to fully support microversions | 18:16 |

| openstackgerrit | garyk proposed openstack/nova: VMware: use vCenter instead of VC https://review.openstack.org/189593 | 19:26 |
| alaski | melwitt: using version 3 was never really supported right? just based on that bug I'm not sure it's worth a revert | 19:27 |
| garyk | melwitt: maybe that is something that should be raised on the list | 19:27 |
| melwitt | alaski: it wasn't, it was being silently changed to '2'. concern is people who wrote client = client.Client('3', ...) and client.do_stuff() code used to work and now it doesn't | 19:28 |
| melwitt | so I wasn't sure | 19:28 |
| *** amotoki has joined #openstack-nova | 19:29 | |
| alaski | melwitt: gotcha, was just reading further and seeing that. definitely not revert worthy imo, better to fail clearly than continue incorrect behavior | 19:29 |
| alaski | we broke a use case that was completely incorrect and didn't do what users thought it did is what I mean to say | 19:30 |
| bauzas | dansmith: around ? was just wondering how to provide something like a NamedTuple as a field ? | 19:30 |
| dansmith | bauzas: dict? | 19:30 |
| bauzas | dansmith: eg. I have a list of tuples like (host, node) | 19:30 |
| bauzas | dansmith: yeah, there is a ListofDicts | 19:31 |
| melwitt | alaski: yeah, what you're saying makes sense. | 19:31 |
| bauzas | dansmith: but I was thinking it was not cool since any dict could be done | 19:31 |
| dansmith | bauzas: yeah, maybe | 19:31 |
| dansmith | bauzas: what do you need to store that for? | 19:31 |
| bauzas | dansmith: that's for the Retry object used by the ReqSpec | 19:31 |
| dansmith | bauzas: which would just be a list of hosts if we didn't have the uuber stupid host,node thing :( | 19:32 |
| bauzas | dansmith: there, we have a list of lists like [['host1, 'node1'], ['host2, 'node2']] which is quite ugly | 19:32 |
| dansmith | it's ugly regardless | 19:32 |
| bauzas | yeah... :( | 19:32 |
| dansmith | jaypipes: host-and-node continues to assault infantile felines ^ :( | 19:33 |
| bauzas | dansmith: wondering if providing a list of ComputeNode object would be cooler | 19:33 |
| bauzas | dansmith: since all of that is actually just a Computenode | 19:34 |
| *** amotoki has quit IRC | 19:34 | |
| dansmith | bauzas: yeah, it would be a sparse compute node object | 19:34 |
| dansmith | with just those two things | 19:34 |
| *** achanda has joined #openstack-nova | 19:34 | |
| dansmith | that's much heavier in terms of messaging load, but maybe not that bad | 19:34 |
| dansmith | how many things will be in the list? | 19:34 |
| *** nihilifer has quit IRC | 19:35 | |
| bauzas | dansmith: for the moment, we're just checking the list and add the tuple if reschedule need | 19:35 |
| dansmith | bauzas: so it would just be $num_retries long/? | 19:36 |
| bauzas | dansmith: so I think a not-saved ComputeNode with just 2 fields set (host, hypervisor_hostname) is enough | 19:36 |

| ijw | Can anyone recall why we didn't make it possible to add and enumerate nova VIF plugging drivers? I seem to recall there was a reason you couldn't just add a new VIF plugging type by adding a chunk of non-core code, but I can't remember what it was | 20:09 |
| ijw | Cos it seems to be a problem we repeatedly stumble over when doing new nova-neutron stuff | 20:10 |

| mriedem | ijw: no idea, it's gross though, and the same thing happens with cinder volume drivers | 20:14 |
| mriedem | fwiw getting changes into nova to talk to a new vif type is generally not controversial | 20:15 |
| mriedem | ijw: you probably want to talk to danpb when he's around | 20:15 |
| openstackgerrit | Vilobh Meshram proposed openstack/nova-specs: Servicegroup foundational refactoring for Control Plane https://review.openstack.org/190322 | 20:15 |
| ijw | Yeah, I do, and he'll know, but I checked first to see if he was there... | 20:15 |
| ijw | I want to get to the point that we can add trivial drivers in Nova, test them, and *then* commit them upstream. But the other point is that when you add a (now out of tree) new driver in Neutron you actually can't supply 3rd party VIF plugging for Nova. | 20:16 |
| mriedem | oh i see what you're saying, when the config option was removed | 20:17 |
| *** VW has quit IRC | 20:17 | |
| mriedem | to load the driver | 20:17 |
| ijw | Yeah - which was, for what it's worth, not a bad thing - the generic driver (which is not really a driver any more) was the right approach | 20:18 |
| ijw | But there is no ability to add types to it without changing Nova, because they're all in a single file and there's no discovery | 20:18 |
| ijw | I dream of the day where VIF drivers register themselves with a (hypervisor, VIF type) and Nova tells Neutron what types it can offer... | 20:18 |
| ijw | I believe the worry was that if that's done by autodiscovery then the behaviour of Openstack is at the whim of what else you might have installed on the system. | 20:19 |
| *** VW has joined #openstack-nova | 20:19 | |
| dansmith | no, the worry was that people would consider it a stable plugin interface | 20:20 |
| dansmith | which is what you're describing | 20:20 |
| mriedem | this is the change that deprecates the option in icehouse https://github.com/openstack/nova/commit/fdffaab6171562487a404963dbf6b7f1f9469a65 - https://github.com/openstack/nova/commit/7561c8ded211d53e8745d1420a73b82bd0fc35cf was the commit to remove it | 20:20 |

| lifeless | cfriesen: can you see how long its been open ? | 20:43 |
| ijw | mriedem: In fact, if you look at the stevedore-driven plugging mechanisms, there's a configuration file (except, when deployed, it usually *isn't* a configuration file, it's a source code file that shouldn't be changed and will be overwritten on upgrade) listing options. My concern is that this makes it impossible to plug 3rd party code into certain plugpoints where it would be valuable. | 20:45 |

| openstackgerrit | Dmitry Guryanov proposed openstack/nova: libvirt: resize ploop disks with prl_disk_tool https://review.openstack.org/182390 | 20:46 |
| mriedem | ijw: as pointed out in that mailing list, there was also a pluggable volume driver thing too that was removed | 20:46 |
| cfriesen | lifeless: how do I check connection established timestamp? netstat? | 20:46 |
| ijw | mriedem: Yeah. Perhaps we should address the underlying problem, then, and have a config item that lists drivers that should register themselves as options. | 20:47 |
| ijw | (for each category) | 20:47 |
| ijw | I fantasise, given that half the day has passed and I've yet to find the time for the 10 minute journey to the office ;) | 20:48 |
| mriedem | ijw: my understanding from the ML thread and history is that there is no stable API for this and that's part of the reason for killing it | 20:48 |
| mriedem | the pluggability i mean | 20:48 |
| dansmith | mriedem: yep | 20:48 |
| mriedem | didn't compute manager and/or conductor used to be pluggable? | 20:48 |
| ijw | mriedem: I would phrase that as 'we choose not to define that API as stable', but yes, it's a fair point. | 20:49 |
| dansmith | not ever conductor, that I know of, but yeah | 20:49 |
| mriedem | so compute manager | 20:49 |
| dansmith | ijw: right, that's exactly it | 20:49 |
| mriedem | i vaguely remember that causing some powervc shenanigans | 20:49 |
| *** alex_klimov has joined #openstack-nova | 20:49 | |
| dansmith | mriedem: jaypipes had a nice list of "pluggable interfaces" that were to be nuked in that thread | 20:50 |
| ijw | The libvirt plugging drivers are awkward, because they have to return a load of crap that (in the case of libvirt) can be folded into a config file in a way that suits the rest of the config file over which they have no control | 20:50 |
| ijw | I shall rephrase and make that tuple (hypervisor, interface-version, plug-type) | 20:50 |
| *** dboik_ has joined #openstack-nova | 20:51 | |
| ijw | As long as the registration API remained stable, then you could put the new version in place prior to an upgrade and have it picked up when nova changed version | 20:51 |
| ijw | (and ignored beforehand) | 20:51 |
| lifeless | cfriesen: sorry, my daughter is using me as a climbing frame atm | 20:52 |
| cfriesen | lifeless: no worries. I've got my own. | 20:52 |
| ijw | Pluggable interfaces serve a purpose when they're not there because they're architecture wank (technical term) | 20:52 |
| lifeless | cfriesen: the thing is to figure out if there is a stuck http connection open from nova | 20:52 |
| lifeless | cfriesen: and then use that to eliminate glance-api as the source of the bug | 20:52 |
| lifeless | cfriesen: another way - bounce the nova-compute process | 20:52 |
