23:04:16	dansmith	I'd surely not want to add this just because someone thinks windows is destabilized by KSM, or because they have some weird unstable driver and turning KSM off changes some race semantics or something
23:05:45	cfriesen	I could see KSM causing brief interruptions to the guest, but I wouldn't expect it to cause actual hangs.
23:06:54	dansmith	right,
23:06:57	dansmith	it can change timing semantics for sure
23:07:06	dansmith	hence the buggy driver example
23:07:18	dansmith	but so can swapping on the host to a much larger degree
23:08:14	openstackgerrit	Dmitry Sutyagin proposed openstack/nova master: libvirt: add disabling KSM via flavor extra specs https://review.openstack.org/591854

00:44:43	mriedem	你好
00:47:56	mriedem	smcginnis: if you're around, we need stable cores for https://review.openstack.org/#/c/591872/ RC2
00:48:46	mriedem	anyone know if jichen is going to clean this up? https://review.openstack.org/#/c/533125/
00:48:53	mriedem	efried: do we need to just update it ourselves?
00:51:16	openstackgerrit	Merged openstack/nova master: Fix service list for disabled compute using MC driver https://review.openstack.org/583936
00:51:25	openstackgerrit	Merged openstack/nova master: Revisons on notifications doc https://review.openstack.org/591621
00:51:32	openstackgerrit	Merged openstack/nova master: use static pages for mitaka and newton release notes https://review.openstack.org/592150
00:52:56	mriedem	tonyb: i guess you'd be a more appropriately time-zoned stable core for https://review.openstack.org/#/c/591872/ for RC2
00:54:40	mriedem	Kevin_Zheng: want to start backporting https://review.openstack.org/#/c/583936/ ? it needs to go to rocky, queens and pike
00:54:47	mriedem	we'll hold it out until we've released rocky though
00:55:01	tonyb	mriedem: on it
01:04:32	Kevin_Zheng	sure
01:05:31	tonyb	mriedem: I'll ping lyarwood
01:06:10	mriedem	tonyb: thanks but he's probably done for the day
01:07:54	tonyb	mriedem: I can single core approve it
01:08:14	tonyb	mriedem: given you're a stable core etc
01:09:57	dansmith	mriedem: tonyb I got it
01:10:29	tonyb	dansmith to the rescue!
01:24:04	mriedem	cool; i've emailed jichen about the zvm docs since those are the only things remaining on the RC2 todo list
01:41:54	mriedem	efried: edmondsw: frankly i care very little if the powervm out of tree driver supports a feature, i don't plan on adding flags to nova to support out of tree features, re: https://review.openstack.org/#/c/591898/

08:05:19	mriedem	tssurya: o
08:05:22	mriedem	o/
08:05:37	mriedem	i've added a couple of things to the cells meeting agenda if you want to take a peek and start lending brain power
08:05:38	tssurya	mriedem: \o/
08:05:45	mriedem	cross cell migration,
08:05:47	mriedem	and down cell
08:06:06	mriedem	our operators want a config option to not return any VMs from nova list if the tenant has any in a down cell
08:06:21	tssurya	mriedem: oh okay
08:06:24	mriedem	to avoid confusing users that thought they had like 3 VMs but now only list 2
08:06:31	mriedem	^ would be pre-microversion
08:06:44	mriedem	b/c with the microversion we can list the down cell VMs with the UNKNOWN status
08:07:06	openstackgerrit	Yikun Jiang (Kero) proposed openstack/nova master: Make monkey patch work in uWSGI mode https://review.openstack.org/592285
08:07:06	tssurya	right so we need to change this now nad backport also I guess to Queens ?
08:07:28	tssurya	before we start merging the UNKNOWN stuff.
08:07:35	mriedem	tssurya: not sure about backports, but maybe if it defaults to current behavior
08:08:33	tssurya	mriedem: the previous behaviour was 500 for down cells, do you suggest the config option to return an empty list if the user has stuff in the down cell then ?
08:08:59	tssurya	instead of skipping
08:09:02	tssurya	that cell
08:09:09	mriedem	originally the behavior was 500 right?
08:09:12	tssurya	yes
08:09:13	mriedem	you fixed that to skip down cells
08:09:16	tssurya	yes
08:09:26	mriedem	so yes, they want an option to say don't skip, but just return an empty list
08:09:32	mriedem	well,
08:09:37	mriedem	if the project has any instances in a down cell
08:09:55	tssurya	okay,
08:10:01	mriedem	i think it would only apply to non-admin instance list; an admin doing nova-list --all-tenants wouldn't apply here
08:10:09	openstackgerrit	fupingxie proposed openstack/nova master: Support list for alias in pci section in nova.conf https://review.openstack.org/592243
08:10:41	tssurya	ack,
08:12:48	tssurya	mriedem: in the agenda you say "show is OK", well show wouldn't work at all before the new microversion, would just be a 500
08:13:01	tssurya	that's okay right ?
08:13:04	mriedem	oh yeah, right
08:13:06	mriedem	yeah
08:13:31	mriedem	nova CLI will do the right thing once you're using latest novaclient and server,
08:13:42	mriedem	in that it will request the latest microversion which will get users the UNKNOWN status behavior
08:15:58	tssurya	yes, speaking of which I am working on that right now: does the new microversion which skips certain keys need the api_samples functional tests ? or is it enough I clearly specify this in the api-ref docs ?
08:17:48	mriedem	would you have a sample of what this looks like in the api-ref docs?
08:17:50	mriedem	i think we probably should
08:17:56	mriedem	and those are generated from the api-samples functional tests
08:18:24	tssurya	mriedem: yea, okay it woud surely be nice to have sample jsons of what a response from down cell versus up cell looks like
08:18:35	mriedem	yeah
08:18:42	tssurya	okay then will add those tests too, but before that will do this pre-microversion thing config
08:18:44	tssurya	and ping you bacl
08:18:46	tssurya	back*
08:20:50	mriedem	ok cool
08:20:53	mriedem	not sure if this should be a bug or what
08:20:59	mriedem	that's why i added it to the meeting agenda
08:21:34	tssurya	right, we kind of skipped yesterday's meeting. so maybe we can discuss it with dansmith when he wkaes up ?
08:25:16	openstackgerrit	Matt Riedemann proposed openstack/nova master: Remove ChanceScheduler https://review.openstack.org/576384
08:28:51	sean-k-mooney	mriedem: o/
08:29:46	sean-k-mooney	mriedem: i tested the live migration between ovs with iptables and ovs with connectracker hosts and you multi port binding changes work well for that case.
08:30:14	mriedem	ho
