| 12:07:25 | sean-k-mooney | stephenfin: while your looking at gate issues https://review.opendev.org/c/openstack/nova/+/814036 also ill joing the ptg shortly | |
| 12:13:51 | sean-k-mooney | oh right we are currently utc +1 | |
| 12:15:22 | opendevreview | Wenping Song proposed openstack/nova master: Cleanup guest process when vm evacuate failed and then deleted https://review.opendev.org/c/openstack/nova/+/814746 | |
| 12:15:28 | stephenfin | sean-k-mooney: I don't think it's trying to start it. I think it's trying to _configure_ it | |
| 12:16:29 | stephenfin | bauzas: I'll miss the first 30 minutes of the PTG, unfortunately | |
| 12:16:42 | bauzas | stephenfin: OK, then I'll flip some topics | |
| 12:17:05 | bauzas | stephenfin: we'll start with gibi's topic about the tox usage | |
| 12:17:24 | sean-k-mooney | well i think stephen is interested in that | |
| 12:18:02 | stephenfin | yeah, I was going to say. I can miss it though. I think a few people understand the problem so I'm sure you'll settle on something sensible | |
| 12:18:41 | sean-k-mooney | stephenfin: im hoping py39 will become a required testing env for yoga | |
| 12:20:17 | sean-k-mooney | just an fyi so we will need to be able to test with that locally but ya we understand what you were tryign to do | |
| 12:22:25 | gibi | stephenfin: ok, so we have global context_manager objects one for the api db and one for the main db. So that is what gets dirty and leaking between tests | |
| 12:23:24 | gibi | do we have some special handling for them in a fixture we use for every test case so in general test cases are not interacting? And don't we use the same fixture in the db_sync tests for a reason? | |
| 12:28:51 | stephenfin | gibi: Sigh, all the DB tests are using NoDBTestCase, so we're not actually using the Database fixture https://github.com/openstack/nova/blob/master/nova/tests/fixtures/nova.py#L611-L617 | |
| 12:29:31 | stephenfin | I still don't know why running other tests first fixes the issue though... | |
| 12:30:57 | gibi | hm, so the normal way to deal with these globals is the Database fixture but for explicit DB testing we dont use that fixture | |
| 12:32:22 | stephenfin | that's my understanding from a quick inspection, but I'm juggling many things today and haven't had time to investigate it properly yet /o\ | |
| 12:32:35 | stephenfin | it does seem strange that DB tests would not use the DB fixture though | |
| 12:32:36 | gibi | I think we have a poison fixture that prevent us touching the DB from a NoDBTestCase but it does not hit for the db_sync tests | |
| 12:33:08 | stephenfin | hmm, true | |
| 12:39:46 | gibi | I'm lost in oslo_db / sqla I guess our poision specific for the way nova objects are accessing the db and it still allows our direct get_engine calls | |
| 12:50:36 | bauzas | reminder : nova sessions start in 10 mins | |
| 13:02:56 | bauzas | sessions start by now :) | |
| 13:03:12 | bauzas | if people wanna come => https://www.openstack.org/ptg/rooms/newton | |
| 13:53:23 | stephenfin | I assume we're on a break? | |
| 13:53:58 | gibi | yepp | |
| 13:54:05 | gibi | stephenfin: you joined for the break :D | |
| 13:54:11 | stephenfin | classic me | |
| 13:54:15 | gibi | :) | |
| 13:55:11 | bauzas | stephenfin: we basically NACK'd all your ideas while you were gone :p | |
| 13:55:19 | bauzas | terrible me | |
| 13:58:19 | bauzas | belmoreira: we have an issue with the interop session being discussed one hour later that conflicts the vncproxy discussion we were planning to have at 15:40pm | |
| 13:58:32 | bauzas | belmoreira: can we make the discussion start at 4pm ? | |
| 13:58:39 | bauzas | dang | |
| 13:59:01 | bauzas | belmoreira: I meant, can we discuss the vncproxy thing at 3pm ? | |
| 13:59:06 | bauzas | (UTC) | |
| 13:59:28 | stephenfin | bauzas: just another PTG so | |
| 13:59:29 | stephenfin | :) | |
| 13:59:36 | belmoreira | bauzas 3pm utc works for me. thanks | |
| 14:00:41 | bauzas | just hope melwitt can be present at this time | |
| 14:00:56 | bauzas | belmoreira: ack, will flip the sessions | |
| 14:11:49 | bauzas | stephenfin: we'll do neutron things until 3pm UTC | |
| 15:07:48 | bauzas | dansmith: are you available ? belmoreira is discussing about moving instances between projects and we're talking of os-chown | |
| 15:08:12 | dansmith | bauzas: not right this moment, but I can try to join soon | |
| 15:08:19 | bauzas | dansmith: cool, appreciated. | |
| 15:11:24 | dansmith | bauzas: actually, this next topic is something I have to stay for, so it'll be a bit yet | |
| 15:11:37 | bauzas | ok | |
| 15:11:47 | bauzas | no worries | |
| 15:14:35 | dansmith | bauzas: I'm here for 15 mins | |
| 15:14:49 | bauzas | ta | |
| 15:17:34 | dansmith | which line is the vnc proxy thing? | |
| 15:17:48 | stephenfin | dansmith: 394 | |
| 15:18:02 | dansmith | ah, in the "after 3pm" thing | |
| 15:18:32 | stephenfin | yeah, I've lost track of how we're picking stuff/what we've covered :) | |
| 15:58:06 | bauzas | side note: Jabra Evolve 2 65 are terrible headsets for a day long wearing them | |
| 15:58:29 | bauzas | my ears are pretty done with it | |
| 15:58:59 | bauzas | stephenfin: yeah, we cherry-picked topics | |
| 15:59:24 | bauzas | I don't wanna move topics too much as it's also confusing | |
| 17:26:48 | bauzas | brinzhang: when you're up, tell me when you want to discuss the cyborg suspend/resume spec ? we can do this either this Thursday 1pm or Friday 1pm if that suits your TZ | |
| 17:27:48 | bauzas | for the moment, placing it at the top of the discussions we have left so it would be discuss this at 1pm, but we can punt it for later | |
| 17:28:40 | bauzas | to nova folks, I flipped topics so the agenda should reflect the first topics to discuss, starting at L357 | |
| #openstack-nova - 2021-10-21 | |||
| 00:22:54 | brinzhang | bauzas:hi, about the suspend/resume an accelerator instance feature, there is no spec, before we completed rebuild/evacuate, shelve/unshelve, I just want to continue | |
| 00:24:33 | brinzhang | bauzas: today, I am not sure that time(1pm) which is ok for me, but if possiable, I think I can, thanks | |
| 08:29:32 | bauzas | brinzhang: OK, then we'll start with your topic, but in case you're not around, I'll punt it until tomorrow | |
| 08:30:39 | gibi | morning Nova | |
| 10:09:43 | sean-k-mooney | for what its worth i think it make sense to proceed with suspend/resume for cyborg without a spec in the same way i hope to do the same for vdpa | |
| 10:10:29 | sean-k-mooney | its just the completion of the existing work which does nto really require much design work so i think specless blueprint and code review should be suffincet in both cases | |
| 10:18:11 | gibi | I'm ok with a specless bp too | |
| 12:11:50 | bauzas | reminder : nova sessions start in 50 mins on https://www.openstack.org/ptg/rooms/newton | |
| 12:15:46 | bauzas | sean-k-mooney: gibi: yup I agree with both of you but given brinzhang asked to discuss for it, let's wait until we do | |
| 12:31:44 | gibi | sure | |
| 12:37:33 | tbarron | bauzas: do you have a window (however large) when you are targeting the virtios topic? manila folks plan to discuss at 23:15 this morning (I know Lee is out of course) | |
| 12:37:40 | frickler | with virt_type=qemu on qemu>=5.2 (bullseye, jammy, centos-stream-8) instances (i.e. rss of the qemu process) seem to use 3x as much ram as the flavor allocates, has anyone seen this behaviour before? it is causing failures in devstack CI with things just going OOM | |
| 12:39:06 | tbarron | bauzas: 13:15 :) | |
| 12:39:30 | tbarron | which isn't morning for lots of people, I know | |
| 12:43:46 | sean-k-mooney | frickler: no but i do know that in qemu 6.0 the -m attibute is nolonger required when using mem-backing args | |
| 12:44:09 | sean-k-mooney | frickler: so in 5.2 where we were seeing libvirt use both way that was still required | |
| 12:45:35 | sean-k-mooney | frickler: actully that chang is in 6.1 https://wiki.qemu.org/ChangeLog/6.1#Memory_backends | |
| 12:46:10 | sean-k-mooney | frickler: so the qemu command line generated form the libvirt xml that i looked at before i think was correct so this sound like a qemu bug | |
| 12:57:31 | bauzas | tbarron: others, sorry was taking a bit of timeoff before we start | |
| 12:57:41 | frickler | sean-k-mooney: do you have some contact at qemu to push that to? | |
| 12:57:50 | bauzas | tbarron: not sure we'll have time to discuss about the Manila spec today | |
| 12:58:12 | bauzas | tbarron: we can start to discuss it for tomorrow 1pm (or later if you prefer) | |
| 12:58:37 | sean-k-mooney | frickler: good question kashyap: do you know who could help root cause this | |
| 12:59:02 | kashyap | What's the context? /me catches up. (In a meeting now) | |
| 12:59:04 | sean-k-mooney | kashyap: context is that qemu on debian seams to be using 2-3x the ram that is allocated to the vm | |
| 12:59:13 | kashyap | What version of QEMU? | |
| 12:59:16 | sean-k-mooney | 5.2 | |
| 12:59:32 | kashyap | Fairly recent (Dec 2020) | |
| 12:59:52 | sean-k-mooney | kashyap: we are seeign this result in OOM issues in the ci hence frickler concern | |
| 12:59:56 | tbarron | bauzas: *bit* is right :D. 1300UTC tomorrow would be great, manila sessions don't start till 1400. | |
| 13:00:26 | stephenfin | I'll be 20/30 minutes late to the PTG sessions again today | |
| 13:00:46 | kashyap | frickler: Very odd; is this something sudden? I can check w/ the upstream, but before that, I'd need a bug (with proper details) | |
| 13:01:05 | kashyap | frickler: Oh, wait | |
| 13:01:26 | kashyap | frickler: virt_type=qemu is already deadly slow: as you might know it's not using any hardware acceleration | |
| 13:02:24 | kashyap | frickler: What is the host OS? (I'm assuming this is a nested env; i.e. the "host" is a level-1 guest. And the baremetal is some cloud-vendor provided) | |
| 13:02:39 | bauzas | nova sessions start by now, people can join with https://www.openstack.org/ptg/rooms/newton | |
| 13:02:57 | kashyap | frickler: I'd need these, to start with: QEMU version and the complete QEMU command-line of the guest. You'll find it here: /var/log/libvirt/qemu/instance-yyyyyyyy.log | |
| 13:04:54 | bauzas | tbarron: okay then let's discuss this at 1300UTC tomorrow | |
| 13:05:30 | bauzas | sean-k-mooney: joing | |
