| gmann | efried: MrRon : there is no plan for nova-tempest-plugin as of now. it came up before also for few scheduler filters test case. we had patch also up to add the tempest plugin for nova. I think currently there is no such case where nova tests cannot be covered with Tempest repo or nova functional test. But if there is any in future we can rethink | 13:47 |

| jaypipes | edleafe: yup, I remember it well. | 14:01 |
| jaypipes | alex_xu: yep, hard to believe, eh?: :) | 14:02 |
| edleafe | I had an equally negative reaction when I learned that | 14:02 |
| jangutter | jaypipes: it was a simpler time, when all Nova needed was a key-value store? | 14:02 |
| jaypipes | edleafe: and we've been data-battling ever since... | 14:02 |
| edleafe | Hey, nova was thrown together over a weekend | 14:02 |
| edleafe | it worked well enough for a POC | 14:02 |
| jaypipes | jangutter: erm, no :) it was a perfect example of how to use Redis as an RDBMS and implement JOINs in Python. | 14:03 |
| alex_xu | jaypipes: yea...I will talk this to everyone when lunch | 14:03 |
| jaypipes | alex_xu: here's another trivia piece for you... there is an entire copy of openwrt Linux distribution in the Nova source repository. | 14:04 |

| sean-k-mooney | mnaser: we disabled the use of multiple port bindings entirely unles neutron and both the source and dest nodes supprot it | 14:33 |
| sean-k-mooney | mnaser: so live migrating form queens to rocky will disable all the new code | 14:34 |
| mnaser | sean-k-mooney: i have a case of a cloud where live migrating from a queens host to rocky host results in the vm being unpingable | 14:34 |
| mnaser | unless you restart the neutron-openvswitch-agent | 14:34 |
| sean-k-mooney | mnaser: that is likely not related to the multiple port binding changes | 14:35 |
| mnaser | sean-k-mooney: well in a r=>r live migration situation, i dont see it | 14:35 |
| mnaser | and after restarting neutron-openvswitch-agent, the vm becomes pingable afterwards, its almost like something isnt properly getting wired up | 14:35 |
| sean-k-mooney | mnaser: did you leave the vm for a period of time or just try to ping it imediatly | 14:36 |
| mnaser | sean-k-mooney: it was on for a while, it was def dead | 14:36 |
| sean-k-mooney | are you using conntrack security group driver or ip tables? | 14:37 |
| sean-k-mooney | basically im wonder if ovs_hybrid_plug in the port bindings was true or false | 14:37 |
| sean-k-mooney | that changes how the port is wired up | 14:38 |
| mnaser | sean-k-mooney: iptables | 14:39 |
| alex_xu | sean-k-mooney: mriedem, I give a try on the resize bug https://review.openstack.org/#/q/status:open+project:openstack/nova+branch:master+topic:bug/1805767, found we miss the pci request also | 14:39 |
| sean-k-mooney | alex_xu: yes you cannot resize to or from a flavor with a pci device alais in the extra specs | 14:41 |
| sean-k-mooney | this is know to be broken | 14:41 |
| *** tbachman has quit IRC | 14:41 | |

| sean-k-mooney | maybe that should work | 14:42 |

| sean-k-mooney | alex_xu: we know we have prolems in this areay im not sure if that one is new thinking about it | 14:42 |
| alex_xu | ok | 14:42 |

| *** xek has quit IRC | 14:45 | |
| sean-k-mooney | mnaser: so iptables means hybrid plug is true which means that os-vif plugged a veth pari into ovs and a per port liunx bridge and libvirt add the vm tap to the linux bridge on migration | 14:45 |
| *** ttsiouts_ has joined #openstack-nova | 14:46 | |
| mnaser | im trying to find here the specific patch that implemented the logic which checks if the dest supports it or not, i suspect *maybe* for some reason it's thinking the other side supports it | 14:46 |
| sean-k-mooney | so neutron should of had time to wire up the ovs port before the vm migrated | 14:46 |
| sean-k-mooney | we do it in the conductor one sec | 14:46 |
| sean-k-mooney | https://github.com/openstack/nova/blob/stable/rocky/nova/conductor/tasks/live_migrate.py#L245-L252 | 14:47 |
| sean-k-mooney | this is the support_extended_port_binding fucntion https://github.com/openstack/nova/blob/stable/rocky/nova/conductor/tasks/live_migrate.py#L39 | 14:48 |
| sean-k-mooney | it just checks for service version >35 on the two nova compute services | 14:49 |
| *** ttsiouts has quit IRC | 14:49 | |
| *** ttsiouts_ has quit IRC | 14:50 | |
| sean-k-mooney | so unless you have backport something in to you queens version that bumps the service version it should be pretty bulletproof | 14:50 |
| sean-k-mooney | all of the new code uses the presence of the vifs object in the migration_data as a sentinel to enable the new workflow | 14:51 |
| mriedem | alex_xu: ok, i see you based that on https://review.openstack.org/#/c/582417/ ? i've had a hard time sorting out why that fails | 14:53 |

| mnaser | sean-k-mooney: is it a valid possible theory that somehow rocky n-cpu doesn't try to plug the port because it assumes the conductor might have already done it | 14:59 |
| mnaser | aka maybe we need to look at the logic in the compute side, ill try to dig in a bit more | 15:00 |
| MrRon | gmann: efried: thanks a lot. That helped me a lot. Have a nice day :) | 15:00 |
| sean-k-mooney | mnaser: no the the plug is initated in both queens and rocky by a direct rpc call form the conductor | 15:02 |
| mnaser | sean-k-mooney: ok, i might be misunderstanding, so i might have some code to read | 15:03 |
| sean-k-mooney | the difference is when is when the port binding are updated in neutron and do we have 1 or 2 bindings | 15:03 |
| mnaser | oh so we always have a binding | 15:03 |
| mnaser | its just either 2 or 1 | 15:03 |
| sean-k-mooney | yes | 15:03 |
| mnaser | okay i see | 15:03 |
| *** cfriesen has joined #openstack-nova | 15:03 | |
| *** dpawlik has quit IRC | 15:04 | |
| mnaser | okay okay, so that's why it would make sense that this wouldn't cause an issue | 15:04 |
| sean-k-mooney | in queens we and one per port and then updated the host id as part of migration | 15:04 |
| mnaser | hmm | 15:04 |
| sean-k-mooney | in rocky we have a source and dest binding per port and atomicly set the dest as active and source as not | 15:04 |
| sean-k-mooney | then if the migration successd we delete the source binding | 15:05 |
| mnaser | because in this cloud i can do rocky=>rocky migrations with no problem | 15:05 |

| mnaser | sorry for all the questions, im just trying to gather some sense to figure out where the issue is | 15:09 |
| sean-k-mooney | no | 15:09 |
| sean-k-mooney | vifs will not be in migrate_data in queens | 15:10 |
| mnaser | hmmmmm | 15:10 |
| sean-k-mooney | that is how we disable it on queens to rocky | 15:10 |
| mnaser | ok that's confusing because if you remember we had that bug with host_mtu | 15:10 |
| mnaser | oh sorry that was in rocky only | 15:10 |
| mnaser | so im assuming that because 'vifs' was added in rocky, that field will be dropped by anything running queens | 15:13 |
| mnaser | so that portion should be skipped | 15:13 |
| mnaser | sigh | 15:13 |
| *** mriedem is now known as mriedem_afk | 15:16 | |

| mriedem | although i guess that wasn't noted in the etherpad, so maybe i thought it elsewhere | 16:58 |
| cfriesen | mriedem: you mean querying server groups by instance? | 16:58 |
| mriedem | yes, rather than return server group information in the servers resource api, | 16:58 |
| mriedem | you filter server groups by member | 16:58 |
| sean-k-mooney | jaypipes: just spent the last few minute talking to the kuryr folks they are now aware of the ML post and will follow up there. | 16:59 |
| bauzas | cfriesen: I agree with mriedem | 16:59 |
| bauzas | cfriesen: ie. not directly providing a new field for the servers API | 16:59 |
| sean-k-mooney | jaypipes: turns out they are storing the os-vif object in the k8s api as annotation on the pod/deployment and k8s stores them in ectd | 16:59 |
| cfriesen | yeah, we've already got the backend DB API to do it. If you and Sylvain are both in favour, I can recommend we switch the spec around to propose that. | 16:59 |

| *** mlavalle has quit IRC | 17:01 | |
| mriedem | at the ptg we said we couldn't show server groups when listing servers with details b/c it would be too inefficient, so we'd restrict to just GET /servers/{server_id} (show) | 17:01 |
| mriedem | but filtering server groups by member would also be useful i think and solve the same problem | 17:01 |

| mriedem | er row 35 | 17:02 |
| mriedem | "Propose a spec if we want this. We could store the server group information with the instance in the instance_extra table, or add a "member" query filter to the GET /os-server-groups API to filter groups returned by server members." | 17:03 |
| openstackgerrit | Filippo Inzaghi proposed openstack/osc-placement master: Change openstack-dev to openstack-discuss https://review.openstack.org/622432 | 17:04 |
| cfriesen | mriedem: okay...and I suppose it'd make more sense to make the filter query keyword "member" since that lines up with the "members" field in the server group response | 17:06 |
| *** takamatsu has quit IRC | 17:06 | |
| mriedem | i commented | 17:09 |
| mriedem | i would make the filter parameter "members" to match the response parameter | 17:09 |
| mriedem | the only question is if we'd use the same "in:" semantics that the placement API uses for things like member_of=in:42896e0d-205d-4fe3-bd1e-100924931787,5e08ea53-c4c6-448e-9334-ac4953de3cfa | 17:10 |
| *** wolverineav has quit IRC | 17:10 | |
| mriedem | cdent: remind me, why did we use "in" rather than just allow member_of to be a list? | 17:10 |
| mriedem | expliciteness? | 17:10 |
| mriedem | "members" for the server groups API filtering seems obvious that it would be a list | 17:11 |
| cdent | mriedem: I think it was following pre-existing patterns and also to make it clear that it means "one of", not "all of" | 17:11 |
| mriedem | ah | 17:11 |
| cfriesen | I think GET /os-server-groups?members=server1,server2 would be clear enough | 17:11 |
| *** sahid has quit IRC | 17:12 | |
| mriedem | but then is that OR'ed or AND'ed | 17:12 |
| *** pcaruana has joined #openstack-nova | 17:12 | |
| cdent | reads as a | 17:12 |
| cdent | AND | 17:12 |
| cdent | to me | 17:12 |
| mriedem | right, me too | 17:12 |
| cfriesen | a given instance can only be a member of one group though | 17:12 |
| cfriesen | so AND doesn't make sense | 17:12 |
| sean-k-mooney | cfriesen: can it | 17:12 |
| mriedem | yes | 17:12 |
| mriedem | you can only specify the group when creating the server, | 17:13 |
| mriedem | you can't add/remove members to/from groups | 17:13 |
| mriedem | despite previous attempts to push that into the api | 17:13 |
| sean-k-mooney | ok then GET /os-server-groups?member=uuid woudl be enough | 17:13 |
| sean-k-mooney | unless you want GET /os-server-groups?members=server1,server2 to tell you if they are in the same group | 17:13 |
| cfriesen | sean-k-mooney: mriedem wanted to be able to query the membership of multiple instances in one call | 17:13 |
| mriedem | i'm not saying i want anything :) | 17:14 |
| mriedem | i'm trying to figure out what the use cases are besides "show me the group my server is a member of" | 17:14 |
| mriedem | since that is the obvious one | 17:14 |
| cfriesen | okay..personally I think the idea would be that you list a bunch of instance via filter, then you want to query the group membership for that list of instances | 17:14 |
| mriedem | but i'd also like to avoid having 4 microversions over time because of AND/OR wrinkles that people want later | 17:14 |
| mriedem | the member_of filtering in GET /resource_providers seems sufficiently flexible for all cases, | 17:15 |
| mriedem | which is why i was saying maybe we model that | 17:15 |

| cfriesen | cdent: a bunch of our users use server groups for anti-affinity | 17:18 |
| cfriesen | cdent: and currently there's no way to easily determine what server group an instance is in | 17:18 |
| cfriesen | cdent: you have to loop over all server groups and check their membership list | 17:18 |
| cdent | sorry mriedem, cfriesen: I was mostly just extending the snark, and not being helpful | 17:18 |
| mriedem | sean-k-mooney: GET /os-server-groups lists all server groups for the tenant | 17:18 |
| mriedem | so yes it can return multiple | 17:19 |
| sean-k-mooney | mriedem: in which case i would expect a list to be returned if it has one entry the are in the same group if it has multiple they are not | 17:19 |
| mriedem | what if we have: (1) GET /os-server-groups?members=server1,server2 (intersection) and (2) GET /os-server-groups?members=in:server1,server2 (union) | 17:19 |
| sean-k-mooney | oh like the compute filter stuff | 17:20 |
| sean-k-mooney | im really not familar enough with this endpont im going to go read the api ref | 17:20 |
| cfriesen | so it looks like the way /resource_providers has done intersection is via two separate "member_of" statements | 17:21 |
| *** sridharg has quit IRC | 17:22 | |
| mriedem | yeah, GET /resource_providers?member_of=AGGA_UUID&member_of=in:AGGB_UUID,AGGC_UUID | 17:22 |
| mriedem | in A and B or C | 17:22 |
| cfriesen | okay, no point wasting people's time further, I'll recommend switching to something along those lines | 17:23 |
| sean-k-mooney | mriedem: i mean it would work but to we need that? | 17:23 |
| mriedem | sean-k-mooney: idk | 17:23 |
| mriedem | i'm also ok with keeping v1 simple | 17:23 |
| mriedem | and letting people bring more use cases later if they have them i guess | 17:23 |
| sean-k-mooney | cfriesen: what was the starlingx/windriver extention by the way | 17:24 |
| mriedem | they showed the server group name/uuid in the server response body | 17:24 |
| mriedem | it wasn't part of the server groups API | 17:24 |
| cfriesen | sean-k-mooney: we just added it to the server details unconditionally, but people are worried about bloating the details | 17:24 |
| sean-k-mooney | oh ok | 17:24 |
| mriedem | it's less about the bloat for me, | 17:24 |
| *** munimeha1 has joined #openstack-nova | 17:24 | |
| mriedem | as the performance | 17:25 |
| mriedem | b/c the server and the group are in different dbs | 17:25 |
| sean-k-mooney | so you trying to create a dedicated endpoint to fulfil the same usecase without imapction openstack server show/list | 17:25 |
| openstackgerrit | Nate Johnston proposed openstack/nova master: Replace neutron-grenade job with grenade-py3 https://review.openstack.org/622453 | 17:25 |
| cfriesen | on which topic...what about the stuff in https://review.openstack.org/#/c/612256 ? (displaying instance topology, pci devices, etc. as part of server details) | 17:25 |
| mriedem | the endpoint already exists, | 17:25 |
| mriedem | this would be adding a filter parameter to it | 17:25 |
| sean-k-mooney | mriedem: your right i prhased that incorrectly | 17:26 |
| mriedem | cfriesen: i think that would have to be part of the server response since we don't have separate endpoints for numa/pci | 17:26 |
| mriedem | we had os-pci years ago until i killed it | 17:26 |
| sean-k-mooney | mriedem: i assuem os-pci listed the avalibe devices or somethin similar | 17:27 |
| mriedem | https://github.com/openstack/nova/blob/juno-eol/nova/api/openstack/compute/plugins/v3/pci.py | 17:28 |
| sean-k-mooney | oh it was part of nova v3 api no onder i dont remember it | 17:28 |
| *** wolverineav has joined #openstack-nova | 17:29 | |

| *** rodolof has quit IRC | 17:29 | |
| *** wolverineav has quit IRC | 17:30 | |
| sean-k-mooney | cfriesen: well i was just wonder if a /servers/{server_id}/toplogy endpoint made sense | 17:30 |
| *** wolverineav has joined #openstack-nova | 17:30 | |
| *** rodolof has joined #openstack-nova | 17:30 | |
| sean-k-mooney | cfriesen: i assume we would not need this endpoint in a list view? | 17:30 |
| melwitt | o/ | 17:31 |
| sean-k-mooney | you could also have a /servers/detail/toplogy endpoint if you did but ill take a look | 17:31 |
| sean-k-mooney | melwitt: welcome back o/ | 17:31 |
| melwitt | thanks sean-k-mooney | 17:31 |
| cfriesen | sean-k-mooney: I'm open to suggestions. :) we just included it in /servers/detail but we don't have ginormous numbers of instances | 17:32 |
| sean-k-mooney | cfriesen: im not sure how i feel about the incltion of physical_mapping | 17:32 |
| mriedem | belmoreira: tssurya: while you're around, did anyone ever create a nova bug to track that issue where you disable computes for maintenance of a cell but because of the allocation candidate result limit, we end up getting novalidhost b/c placement returns all disabled computes? | 17:32 |
| cfriesen | that would be for admin-only by default policy | 17:32 |
| cfriesen | sean-k-mooney: it's useful for admins to debug issues, making sure that things are where nova thinks they are | 17:33 |
| sean-k-mooney | it is but im still not sure how i feel about it which is a good thing as it means i dont hate it | 17:34 |
| cfriesen | lol | 17:34 |
| sean-k-mooney | cfriesen: i think the respoce for this would be large enough to warrent its own enpoint honestly | 17:34 |
| cfriesen | sean-k-mooney: could you mention that on the spec review? | 17:35 |
| sean-k-mooney | yes | 17:35 |
| sean-k-mooney | i also need to read the sepc | 17:36 |
| sean-k-mooney | oh its nice an short | 17:36 |
| sean-k-mooney | i just went strait to the json responce | 17:36 |
| mriedem | it's nice and short b/c it does'nt say anything | 17:36 |
| cfriesen | the other thing I'm not sure how to handle is jaypipes comment about not wanting a JSON blob | 17:36 |
| mriedem | user wants this, so do it | 17:36 |
| mriedem | i definitely don't think we should be dumping random unversioned json blobs out of the api | 17:37 |
| sean-k-mooney | well in this case i think this is 75% admin only stuff | 17:37 |
| mriedem | we had ^ with the diagnostics api already | 17:37 |
| sean-k-mooney | mriedem: i agree with that | 17:37 |
| *** jmlowe has quit IRC | 17:38 | |
| *** diliprenkila has joined #openstack-nova | 17:38 | |
| sean-k-mooney | i know i had started working on convertin alot of the pic request/alias stuff to ovos a while back. we would want this endpont to be independet of the libvirt definitons | 17:38 |
| mriedem | melwitt: https://review.openstack.org/#/q/status:open+project:openstack/nova+branch:master+topic:bug/1806064 fixes a quota check cleanup regression since pike | 17:39 |
| cfriesen | what about adding the numa topology info to the diagnostics endpoint? | 17:39 |
| sean-k-mooney | cfriesen: the priamary usecase is admin dubuging yes | 17:39 |
| mriedem | cfriesen: that's probably a better place for that kind of informatoin | 17:39 |
| melwitt | mriedem: thx. had just opened a tab for that one | 17:39 |
| mriedem | cfriesen: given it's already got hardware-specific details in it | 17:40 |
| mriedem | i think it also has some flexibility for virt-specific backend stuff | 17:40 |
| sean-k-mooney | looking at https://developer.openstack.org/api-ref/compute/?expanded=list-server-groups-detail,show-server-group-details-detail,show-server-diagnostics-detail#servers-diagnostics-servers-diagnostics ya | 17:41 |
| sean-k-mooney | it has a driver field | 17:41 |
| mriedem | it is a bit more biased to current usage though, it gets info from the hypervisor | 17:41 |
| *** k_mouza has quit IRC | 17:42 | |
| sean-k-mooney | we could proably extend the cpu_details and memory_details dicts to include the info | 17:42 |
| mriedem | this is the libvirt code fwiw https://github.com/openstack/nova/blob/5f648dda49a6d5fe5ecfd7dddcb5f7dc3d6b51a6/nova/virt/libvirt/driver.py#L8609 | 17:42 |
| *** jdillaman has quit IRC | 17:43 | |
| cfriesen | maybe add a new "topology" section? | 17:43 |
| mriedem | so there are 3 options: (1) include it directly in the server response details, (2) add a new subresource endpoint to servers (for show on a single server only), (3) make it part of diagnostics (which is also per server) | 17:43 |
| mriedem | at this point you might want to take those 3 options to the ML | 17:43 |
| cfriesen | okay, can do. | 17:43 |
| *** mlavalle has joined #openstack-nova | 17:43 | |
| sean-k-mooney | well we are already passing in the instance to that function and its in the dirver so that seam very doable | 17:43 |
| mriedem | b/c alex_xu and gmann will probably also have input | 17:43 |
| mriedem | sean-k-mooney: b/c the information they get comes from the driver, | 17:44 |
| mriedem | for what this wants, we don't really need the driver, | 17:44 |
| mriedem | we're just dumping info out of the db | 17:44 |
| sean-k-mooney | mriedem: that is true altough i wonder if any of the driver treat the extra specs different | 17:45 |
| mriedem | idk, i don't deal in numa | 17:45 |

| cfriesen | maybe a weird question, but how does nova-manage handle authentication? is it based off the config file and whoever is allowed to run the executable? | 19:43 |
| cfriesen | I'm trying to sort out dependencies | 19:44 |
| *** wolverineav has quit IRC | 19:46 | |
| melwitt | cfriesen: yes. I think it doesn't yet [or may never] do anything like call out to REST APIs (doesn't need keystone auth). the auth info for the database access is part of the [database]connection and [api_database]connection settings in the nova config file. and generally admin RequestsContext are used so nova-manage is able to access any database record | 19:49 |

| prometheanfire | you remember what we've done in the past for libvirt fails on rhel based stuff and uppdating stable branches? https://review.openstack.org/622548 the intention is that they would backport to ocata afaik | 20:07 |
| mriedem | prometheanfire: well, upper-constraints is less of an issue, it's lower-constraints that really matters for stable | 20:12 |
| mriedem | i have no idea what the support matrix is for stable/ocata wrt centors | 20:12 |
| mriedem | *centos | 20:12 |
| prometheanfire | mriedem: true, problem is libvirt starting to fail due to a minor release... | 20:12 |
| *** wolverineav has joined #openstack-nova | 20:12 | |
| prometheanfire | on gentoo I've always left it uncapped so the latest stable is always used | 20:13 |
| prometheanfire | haven't had complaints, yet | 20:13 |
| *** manjeets_ has joined #openstack-nova | 20:13 | |
| * prometheanfire should remove pike from the repo soon | 20:13 | |
| mriedem | so centos 7.6 (released yesterday) has libvirt 4.5 and therefore libvirt-python 4.4 from u-c fails to build with it, because it needs to be >= 4.5 right? | 20:14 |
| *** manjeets has quit IRC | 20:14 | |
| prometheanfire | something like that, ya | 20:14 |
| prometheanfire | the author would know more I imagine | 20:15 |
| mriedem | i left a comment, only wondering why 4.10 is used over 4.5 | 20:15 |
| mriedem | to match libvirt | 20:15 |
| prometheanfire | mainly because it's the latest release and using a newer one is fine (and hopefully future proofs stuff a little) | 20:16 |
| mriedem | ok, shrug; it's weird having something in u-c that is so dependent on native package versions | 20:20 |
| mriedem | it would also be weird to me to update libvirt-python in stable/ocata u-c at this point, especially given what limited CI coverage we run on ocata now | 20:20 |
| mriedem | i know nova doesn't run centos jobs on ocata (or anywhere ever) | 20:21 |
| prometheanfire | ya, iirc libvirt-python is the only thing like that | 20:21 |
| mriedem | what version of centos does infra support for ocata? | 20:21 |
| mriedem | anyway, this is probably something for the -stable or -qa channel or something | 20:22 |
