#openstack-nova - 2020-05-20
12:21:41 nightmare_unreal probably
12:22:02 sean-k-mooney nightmare_unreal: the first command should still work without the second
12:22:26 nightmare_unreal true , maybe it should throw error then.
12:22:38 sean-k-mooney maybe just add a retry loop to your state change check
12:22:51 sean-k-mooney e.g. try 3 times with a 5 second sleep or something
12:22:56 nightmare_unreal yeah i was thinking same. maybe 3 tries with some timeout
12:23:06 nightmare_unreal cool thanks sean-k-mooney
12:55:31 openstackgerrit Jiri Suchomel proposed openstack/nova master: Add ability to download Glance images into the libvirt image cache via RBD https://review.opendev.org/574301
12:56:21 jsuchome lyarwood: new PS ^. It's not pretty, but I think it's more readable than before.
13:23:51 openstackgerrit Lee Yarwood proposed openstack/nova master: libvirt: Remove blockjob.end == 0 workaround resolved in libvirt v2.3.0 https://review.opendev.org/729596
13:23:51 openstackgerrit Lee Yarwood proposed openstack/nova master: libvirt: Track blockjob status in DEBUG when polling for completion https://review.opendev.org/729595
13:24:28 lyarwood kashyap: random question, what's the preferred way of polling blockjobs today? A comment from Matt I've removed from the comments above suggests there was an events framework we could use?
13:24:38 lyarwood jsuchome: ack will look shortly
13:24:57 kashyap lyarwood: Hiya
13:25:17 kashyap lyarwood: Yes, the idea we discussed in the past was to listen on:
13:25:36 kashyap _BLOCK_JOB_READY events that QEMU (which in turn libvirt also relays) emits once a copy job has synced
13:26:04 kashyap lyarwood: I recall writin up that design somewhere, need to dig; but buried in a few downstream tasks before I go offline tomm & Fri
13:26:27 kashyap Give me a few, I'll find the relevant pointers :)
13:26:29 lyarwood ack np
13:26:33 lyarwood thanks
13:29:06 kashyap lyarwood: Context-1: the thorny problem CI in Nova identified was this write-up: http://lists.openstack.org/pipermail/openstack-dev/2016-October/105158.html ("Debugging blockRebase() - "active block copy not ready for pivot")
13:29:38 openstack bugzilla.redhat.com bug 1382165 in libvirt "virDomainGetBlockJobInfo: Adjust job reporting based on QEMU stats & the "ready" field of `query-block-jobs`" [Unspecified,Closed: nextrelease] - Assigned to pkrempa
13:29:38 kashyap lyarwood: Context-2: from the above, I filed this libvirt bug in 2016, and is fixed (in Jan-2019): https://bugzilla.redhat.com/show_bug.cgi?id=1382165
13:31:45 kashyap lyarwood: Context-3: https://libvirt.org/git/?p=libvirt.git;a=commit;h=73ce3911a
13:31:49 openstackgerrit Lee Yarwood proposed openstack/nova master: libvirt: Remove blockjob.end == 0 workaround resolved in libvirt v2.3.0 https://review.opendev.org/729596
13:31:49 openstackgerrit Lee Yarwood proposed openstack/nova master: libvirt: Track blockjob status in DEBUG when polling for completion https://review.opendev.org/729595
13:31:53 kashyap (There "some clients" is referring to OpenStack :-))
13:32:25 kashyap So yeah, in short: what's needed is to listen on VIR_DOMAIN_BLOCK_JOB_READY event.
13:32:49 kashyap Instead of polling (to avoid the race that we debugged in the Context-1 link)
13:34:23 lyarwood https://libvirt.org/html/libvirt-libvirt-domain.html#virConnectDomainEventBlockJobCallback using this I assume?
13:34:32 lyarwood we don't want to listen over QMP
13:35:01 kashyap lyarwood: No, we're not doing over QMP, of course
13:35:17 kashyap libvirt itself emits events; there's even an XML flag for the 'ready' bit
13:35:43 lyarwood kk
13:35:52 kashyap (The actual thing is being transmitted over QMP anyway; but we don't manually do it; that's what I meant)
13:36:52 lyarwood yup understood thanks
13:37:16 kashyap And check out this bit (read it in full in the URL): "The attribute 'ready', if present, tracks progress of the job [...]": https://libvirt.org/formatdomain.html
13:37:26 kashyap [Under the 'mirror' documentation]
13:39:29 lyarwood kashyap: yeah we already poll on that
13:40:21 kashyap Ah, nod. /me bbiab; need to finish this other bit early.
13:40:26 lyarwood kashyap: I added that a while ago https://review.opendev.org/#/c/399735/
13:40:29 kashyap (But I reviewed your clean-up; looks good to me)
13:40:54 lyarwood ack thanks
13:41:06 kashyap lyarwood: Oh, yea; now I recall it. Thx
14:29:43 lyarwood artom / melwitt / stephenfin ; would you all mind taking a swing at https://review.opendev.org/#/c/631294/ sometime this week?
14:30:46 artom lyarwood, ack
14:31:55 lyarwood thanks, it's a total pig thanks to the backport requirement but all I can do at the moment

14:47:53 stephenfin lyarwood: ack, I was waiting on the WIP patches theren ow
14:47:54 stephenfin *now
15:47:39 jsuchome lyarwood: fyi, I missed broken tests, will have to rewrite it once more...
15:50:15 lyarwood jsuchome: ack np I was waiting on CI for that very reason :)
15:54:49 jsuchome I accidentally ran wrong tests localy and was surprised it was passing :-)

08:45:23 openstackgerrit junbo proposed openstack/nova master: use dpdk interface type for ovs dpdk representor port https://review.opendev.org/729874
08:47:31 lyarwood Random question to start the day, some folks downstream noticed that after an ungraceful shutdown and reboot of a compute that instances remained in ACTIVE with a vm_state of active and a power_state of NOSTATE. Can anyone recall why we don't just mark things as SHUTOFF etc?
08:52:06 gibi lyarwood: in my experience we mark them SHUTOFF after a compute host restart
08:52:50 lyarwood gibi: this might be a regression then as I can reproduce this in devstack
