23:20:53	sean-k-mooney	vms can still be killed if a numa node has no memoy left and the kernel need to allocate some on that node but the host othersise has free ram
23:21:33	sean-k-mooney	our just make all your vms use hugepages that works too
23:25:06	cfriesen	that's what we do by default (2M pages)
23:26:36	sean-k-mooney	cfriesen: ya we spent 6 months trying to track down what was causeing OOM to kill our vms in the the intel nfv ci and it turned out to be this. hugepages fixed it
23:27:31	sean-k-mooney	the anoying thing was it took about 2-3 weeks to start showing up as it need the memory to become fragmented enough to force it

07:56:50	bauzas	good morning folks
08:01:46	hrw	Graphical console stuff got merged! yay and hurray!
08:10:28	bauzas	hrw: you might be interested in https://bugs.launchpad.net/nova/+bug/1741319
08:10:28	openstack	Launchpad bug 1741319 in OpenStack nova-compute charm "arm64: Migration pre-check error: CPU doesn't have compatibility." [Medium,Incomplete]
08:10:42	bauzas	hrw: just let me know if that's a valid bug so I can triage it
08:11:35	hrw	bauzas: there is no cpu_model = host-model on aarch64
08:12:07	hrw	bauzas: so bug is valid and not solvable
08:12:22	bauzas	hrw: that's what I understood
08:12:32	bauzas	since we compare models for live migrating
08:14:28	hrw	added note
08:15:34	bauzas	hrw: so, for the moment, live-migration isn't supported for ARM64, I guess then
08:15:49	bauzas	if so, we should amend the doc
08:15:49	hrw	bauzas: not quite.
08:16:06	hrw	bauzas: you may migrate but between same cpus
08:16:36	hrw	will ask our testers to check it (as my setup is all-in-one)
08:17:11	bauzas	hrw: the reporter says they have exact CPUs
08:17:15	bauzas	exact same*
08:17:33	bauzas	hrw: but the point is, nova is checking something that ARM64 libvirt doesn't pass, that's ity
08:17:45	hrw	ok
08:18:07	bauzas	so that probably needs some kind of discussion about the possible solutions
08:18:25	bauzas	we could conditionally don't care of cpu models if arm64
08:18:32	bauzas	or we could ask libvirt to provide a single one
08:18:49	bauzas	I tend to consider the latter as the best one
08:19:07	hrw	the problem is that even kernel does not provide cpu model
08:19:18	bauzas	I know
08:19:21	hrw	/proc/cpuinfo is useless
08:19:32	bauzas	it's all about having the same XML
08:19:37	hrw	DMI data is useless too
08:19:38	bauzas	hence the interface
08:20:15	hrw	bauzas: you can not set 'random' values as cpu model. that's why libvirt does not set that at all
08:22:25	bauzas	I see
08:22:57	bauzas	hrw: anyway, I leave the bug one
08:22:59	bauzas	open*
08:23:00	hrw	sure
08:23:13	bauzas	that's worth considering the options
08:23:29	bauzas	hrw: but we also have a support matrix page
08:23:46	bauzas	hrw: and I feel we should explain that nova live-migration isn't supported for aarch64
08:23:56	bauzas	'not supported' doesn't mean that you can't do
08:24:05	bauzas	just that you have to workaround that
08:24:31	bauzas	hrw: know the support matrix ?
08:24:53	hrw	bauzas: heard about it but not checked
08:25:03	bauzas	ok, giving you the link
08:25:51	bauzas	hrw: https://docs.openstack.org/nova/latest/user/support-matrix.html and https://docs.openstack.org/nova/latest/user/feature-classification.html
08:26:03	hrw	thx
08:26:38	hrw	looks like we need to fill whole new column ;D
08:28:48	bauzas	hrw: you got my idea
08:29:00	openstackgerrit	Thomas Goirand proposed openstack/python-novaclient master: Fix crashing console-log https://review.openstack.org/541610
08:35:34	bauzas	hrw: volunteer for documenting it ? if so, ping me when your change is up :)
08:35:48	bauzas	hrw: ideally, I'd love to merge it before RC1 which is tomorow
08:35:49	hrw	bauzas: mailing my team now
08:35:53	bauzas	tomorrow
08:36:13	hrw	bauzas: as I do not have multinode setup which is required for some tests
08:36:26	bauzas	I'm just surprised to see operators beginning to deploy on ARM64 machines while Nova doesn't officially support it
08:36:42	bauzas	hrw: there is a question mark lebelling possible
08:36:46	bauzas	labelling
08:36:57	bauzas	like say "?" if you don't know the answer yet
08:36:59	hrw	bauzas: we concentrated more on getting whole stack running more than on small issues here and there
08:37:10	bauzas	that's understandable
08:37:36	hrw	bauzas: Kolla work took most of my previous year and it paid off nicely.
08:37:42	bauzas	hrw: I have a couple of Pi3 at home, do you think I could test myself ? ;)
08:38:09	hrw	I just run a job on Jenkins and in 2.5h I have ~250 images built and pushed to hub.docker so we can use those
08:38:54	hrw	bauzas: haha
08:39:25	hrw	I hope that once we move jenkins builder to better network I will fit build phase in 1.5h
08:41:23	rabel	could we merge https://review.openstack.org/#/c/535871/ ? it's a backport of a small docu fix to stable/pike
