19:26:15	mriedem	https://docs.openstack.org/nova/latest/configuration/config.html#glance.verify_glance_signatures
19:26:32	melwitt	mriedem: yeah, he said it's different than the signature verify
19:26:48	melwitt	and I just can't find it anywhere
19:26:57	mriedem	is this based on his ocata cloud?
19:27:10	melwitt	it might be
19:27:14	mriedem	https://docs.openstack.org/nova/pike/configuration/config.html#libvirt.checksum_base_images
19:27:21	mriedem	that stuff has been removed
19:27:30	melwitt	oh, dangit
19:27:38	mriedem	dagnabbit even
19:28:03	melwitt	yeah, for sure
19:28:40	melwitt	there goes that lead :(
19:28:41	sean-k-mooney	artom: the xml looks correct and it was updated
19:29:16	donnyd	what would be real slick is to just mount the same share for glance filestore backend and nova image cache
19:29:23	mriedem	make way
19:29:35	donnyd	that way once the image is uploaded the hypervisor would have immediate access

19:30:46	openstackgerrit	Matt Riedemann proposed openstack/nova master: Add zones wrinkle to TestMultiCellMigrate https://review.opendev.org/643450
19:31:12	mriedem	gibi: stephenfin: dansmith: ^ i've rebased and moved the already +2'ed and less controversial things to the bottom to help move those through
19:32:24	sean-k-mooney	artom: http://paste.openstack.org/show/765671/
19:32:30	donnyd	mriedem: you are supposed to wait for Friday afternoons for that kind of action.. so my CI has something to do... it gets lonely and bored
19:32:37	sean-k-mooney	that the xml before and after the migration
19:33:14	mriedem	donnyd: i wanted to test your CI's image download capabilities
19:33:29	donnyd	LOL - thanks
19:35:05	artom	sean-k-mooney, I think the best thing would be to write up a comprehensive test report
19:35:30	artom	I'm fairly confident that the XML part works, that's been there since Stein
19:35:49	artom	It's more the new surprises - pci_requests from the migration_context, etc
19:36:04	artom	It doesn't help that the path series keeps changing under you
19:36:05	artom	But yeah
19:36:20	artom	I think testing by a more or less independent third party would be awesome :)
19:36:35	artom	I need to drop for a bit while I reconnect to phone's hotspot
19:36:39	artom	brb
19:37:34	sean-k-mooney	well im not sure i qualify in that regard but ill test it none the less
19:42:29	sean-k-mooney	the migration context is here http://paste.openstack.org/show/765743/
19:42:59	sean-k-mooney	and the pci request in the instance extra table are empty
19:43:03	sean-k-mooney	mysql> select pci_requests from instance_extra as ie where ie.instance_uuid='b304fedf-aa31-4990-9a74-29729eed336d';
19:43:05	sean-k-mooney	+--------------+
19:43:07	sean-k-mooney	| pci_requests |
19:43:09	sean-k-mooney	+--------------+
19:43:11	sean-k-mooney	| [] |
19:43:13	sean-k-mooney	+--------------+
19:44:28	artom	Yey :(
19:44:36	artom	At least we know we weren't wrong to worry
19:45:11	sean-k-mooney	the pci device will will be claimed with the instance uuid in the pci tracker
19:45:28	sean-k-mooney	but its not correct.
19:45:31	artom	Yeah, but won't that screw up future operations?
19:45:47	artom	Suddenly you can evacuate to a host with no SRIOV, for example
19:46:07	sean-k-mooney	i would have to do more testing but non nessiarally
19:47:15	artom	Still seems dangerous
19:47:36	artom	I mean, I want NUMA LM to land a *lot*, but there's a minimum level of quality here ;)
19:47:44	artom	And that's not part of it
19:49:09	sean-k-mooney	ya i know. the request_spec still has the orginal pci_request in it and we do not support pci hot attach
19:49:37	sean-k-mooney	that is the request spec http://paste.openstack.org/show/765824/
19:49:38	openstackgerrit	Matt Riedemann proposed openstack/nova master: FUP for I66d8f06f19c5c631e33208580428aa843abb38d2 https://review.opendev.org/678951
19:52:29	sean-k-mooney	stephenfin: by the way i think we need to apply https://review.opendev.org/#/c/675776/
19:52:40	sean-k-mooney	i am seeing some other issue that that will likely fix
19:54:50	sean-k-mooney	artom: with the same code if i use a non numa flavor the pci reuests are not removed
19:55:17	sean-k-mooney	artom: we might be able to use the temporay mutation thing to ensure that the change is not saved
19:56:31	artom	sean-k-mooney, errr...
19:56:37	artom	We want to save the *other* stuff
19:59:05	mriedem	sean-k-mooney: so definite -1 here right? https://review.opendev.org/#/c/635669/39/nova/compute/resource_tracker.py@307
19:59:10	mriedem	can someone do that?
19:59:42	sean-k-mooney	mriedem: yes
20:02:31	sean-k-mooney	commeted and -1'd
20:06:21	artom	Sheesh, rub it in, will'ya
20:07:03	mriedem	i can run a -2 into it if that helps
20:07:06	mriedem	*rub
20:07:07	openstackgerrit	Matt Riedemann proposed openstack/nova master: Update help for image_cache_manager_interval option https://review.opendev.org/678954
20:07:10	sean-k-mooney	rubbing salt in a wound helps it heal :P
20:07:26	artom	mriedem, no, rubbing a -2 does something entirely different
20:12:18	sean-k-mooney	in other new https://bugs.launchpad.net/nova/+bug/1804502 is a pain
20:12:19	openstack	Launchpad bug 1804502 in OpenStack Compute (nova) "Rebuild server with NUMATopologyFilter enabled fails (in some cases)" [Undecided,In progress] - Assigned to David Hill (david-hill-ubisoft)
20:12:55	sean-k-mooney	and yes i know its a feature not a bug but i think i need to go figure out how to make that work for U ...
20:12:58	mriedem	cfriesen has a duplicate of that i think
20:13:12	sean-k-mooney	ya its a long knonw issue
20:13:26	sean-k-mooney	none of the filters are really aware of rebuild/resize
20:13:39	sean-k-mooney	and they all reate the request as a new spawn
20:13:56	sean-k-mooney	so we need double the capasity yada yada yada
20:14:12	sean-k-mooney	its fixable it just a pain
20:14:38	sean-k-mooney	and we have had more important things like moveing this stuff to placment
20:14:43	mriedem	the filters are definitely aware of rebuild now
20:14:55	sean-k-mooney	not all of them
20:15:05	sean-k-mooney	or rahter they have to be coded to be aware
20:15:19	mriedem	correct, https://github.com/openstack/nova/blob/master/nova/scheduler/filters/numa_topology_filter.py#L26
20:15:26	sean-k-mooney	we now at least go back to the schduler when the image changes
