15:59:29	aarents	1) allow qcow2 instance to be live-migrated on raw host but not converted. target host have a mix of qcow2 & raw instance.
15:59:31	aarents	2) allow qcow2 instance to be live-migrated but converted (bigger patch)
16:01:55	aarents	mriedem: are you open on 2 solution or only on solution 2 ?
16:02:55	mriedem	aarents: i think 1 is a can of worms
16:03:02	mriedem	does 'can of worms' translate?
16:03:32	sahid	bucket of bugs i guess
16:03:34	mriedem	because that means, the code is going to have things like, "if CONF.libvirt.images_type OR SPECIAL CASE LIVE MIGRATION"
16:10:18	openstackgerrit	Merged openstack/nova master: placement: Allocation.consumer field https://review.openstack.org/565405
16:13:38	aarents	mriedem: we made test in our environnement, for solution one, all main action seems to work great for qcow2 instance one a raw host resize/suspend/hardreboot

16:23:54	stephenfin	That was the single worst "rebase" of my life
16:24:04	stephenfin	Three whole days, gone like that
16:31:20	crazik	hello. is it safe to truncate migrations table when all migrations are done? completed/confirmed/error/...
16:31:51	mriedem	crazik: as in purge?
16:31:58	mriedem	archive then and then purge for deleted instances
16:32:05	crazik	i did it.
16:32:08	mriedem	nova-manage db archive_deleted_rows --until-complete --verbose --purge
16:32:18	mriedem	crazik: if they are archived, then yeah purge is fine
16:32:31	crazik	still >400 entries
16:32:58	crazik	my question in general is: why should I need this
16:33:32	crazik	I think I have some troubles similar to https://bugzilla.redhat.com/show_bug.cgi?id=1403728
16:33:34	openstack	bugzilla.redhat.com bug 1403728 in openstack-nova "Unexpected "Instance not resizing, skipping migration" caused by nova evacuation" [Medium,Closed: errata] - Assigned to ratailor
16:33:59	crazik	and wonder what are dependencies on this table.
16:34:10	dansmith	mriedem: heh, we have no tests for check_can_live_migrate_destination in rpcapi
16:34:15	crazik	if no migration is running now
16:39:05	mriedem	dansmith: psh who needs tests
16:39:20	mriedem	crazik: why do you need migration records for instances that aren't migrating?
16:39:33	mriedem	there is an API to see them for one thing, for like auditing and debugging failures
16:39:57	mriedem	there are also places in the code that rely on them existing for making decisions, like bringing up an evacuated host
16:40:30	crazik	mriedem: I had some issues with migration and need to exclude one reason: old migrations
16:44:03	mriedem	crazik: which release are you on?
16:44:17	mriedem	the archive stuff was broken a few releases ago
16:44:25	mriedem	or, didn't completely cleanup
16:44:40	crazik	Pike
16:44:57	crazik	well, at migration between Ocata and Pike
16:45:13	crazik	few first compute were ok
16:45:27	crazik	but next one: few of running - refused to live migrate
16:45:32	crazik	(error status in migration)
16:46:12	crazik	and ShutOff -also refused migration. done after nova-compute stop and evacuate-host
16:46:54	mriedem	if the migration is failing, it's not likely due to old migration records in thedb
16:47:11	mriedem	did you look at the nova-compute logs on each host involved in the live migration?
16:47:29	openstackgerrit	Dan Smith proposed openstack/nova master: Make check_can_live_migrate_destination use long_rpc_timeout https://review.openstack.org/575493
16:47:31	dansmith	mriedem: ^
16:47:32	mriedem	could also be scheduler or conductor logs, dependong on where it failed
16:47:38	mriedem	dansmith: sweet
16:47:51	dansmith	now, I've been up for almost four hours without food, so.. food.
16:48:05	mriedem	sustain yourself on a job well done
16:48:07	crazik	mriedem: nothing special was there
16:48:23	mriedem	crazik: if it failed and went into error state, there must be something in the logs when it failed
16:48:47	crazik	hm, I will try to find that.
16:49:00	crazik	maybe I skipped something
16:57:35	mriedem	another one bites the dust https://blueprints.launchpad.net/nova/+spec/enhanced-kvm-storage-qos
16:57:59	mriedem	and https://blueprints.launchpad.net/nova/+spec/xenapi-image-handler-option-improvement
16:59:34	openstackgerrit	Eric Fried proposed openstack/nova master: DNM: Leaked nrp-in-alloc-cands behavior https://review.openstack.org/575497
17:16:42	openstackgerrit	Elod Illes proposed openstack/nova master: Reject interface attach with QoS aware port https://review.openstack.org/570078
17:16:43	openstackgerrit	Elod Illes proposed openstack/nova master: Reject networks with QoS policy https://review.openstack.org/570079
17:23:15	openstackgerrit	Matt Riedemann proposed openstack/nova master: Add troubleshooting item about ignored microversions https://review.openstack.org/575506
17:23:16	mriedem	melwitt: see if ^ makes sense re jmlowe's microversion issue
17:23:51	dansmith	mriedem: dude, hold on,
17:23:57	dansmith	she's reviewing my rpc timeout patch right now
17:23:59	dansmith	wait your turn
17:24:03	mriedem	INTERRUPT
17:24:14	melwitt	lol
17:24:17	mriedem	dansmith: see if ^ makes sense re jmlowe's microversion issue
17:24:23	dansmith	eff.
17:24:26	dansmith	that backfired
17:24:29	mriedem	ha
17:25:25	dansmith	I was too busy being emo in the tc channel to pay attention to that convo
17:26:52	melwitt	*group hug*
17:30:29	dansmith	mriedem: we could make novaclient look for the server side version headers and warn you if you used a microversion but clearly hit the old api endpoint right?
17:32:44	dansmith	or maybe just fail if you asked for a microversion and hit the old api, so you know it's not going to do the thing you asked for
17:35:28	dansmith	or maybe that's what you meant by the words around the legacy wrapper thing
17:50:48	mriedem	dansmith: more the latter
17:50:55	mriedem	doing anything client side is whack a mole
17:58:44	openstackgerrit	Chris Dent proposed openstack/nova master: Optional separate database for placement API https://review.openstack.org/362766
17:58:45	openstackgerrit	Chris Dent proposed openstack/nova master: Isolate placement database config https://review.openstack.org/541435
17:58:46	openstackgerrit	Chris Dent proposed openstack/nova master: Ensure that os-traits sync is attempted only at start of process https://review.openstack.org/553857
17:59:48	openstackgerrit	Chris Dent proposed openstack/nova master: Add PLACEMENT_DB_ENABLED=True to the nova-next job https://review.openstack.org/564067
18:12:11	melwitt	seems like zuul is stuck
18:20:44	melwitt	kashyap: is this blueprint considered complete? it looks like all related changes have merged https://blueprints.launchpad.net/nova/+spec/libvirt-cpu-model-extra-flags
18:30:54	openstackgerrit	Matt Riedemann proposed openstack/nova master: Fix nits from trusted certs notification change https://review.openstack.org/575521
18:38:28	efried	Sundar: Howdy
18:38:44	efried	stephenfin still around by any chance?
18:40:13	Sundar	efried: Hi, how are you doing?
18:40:20	efried	Living the dream.
18:40:22	Sundar	What geo are you in?
18:40:32	efried	Central Texas (Austin area)
