18:43:44	sean-k-mooney	cause you could do 8 if they have more then 10 cores with a bios tweek but we only need 2
18:44:04	sean-k-mooney	with 2 numa nodes we can test everything
18:44:38	sean-k-mooney	stx is starlingX
18:44:39	donnyd	https://ark.intel.com/content/www/us/en/ark/products/64607/intel-xeon-processor-e5-4620-16m-cache-2-20-ghz-7-20-gt-s-intel-qpi.html
18:44:41	donnyd	sandy bridge
18:44:47	donnyd	no may not be helpful
18:44:56	openstackgerrit	Merged openstack/nova master: Ensure online migrations have a unique name https://review.opendev.org/679096
18:45:00	artom	sean-k-mooney, yeah, they wanted to test NUMA LM as well
18:45:08	openstackgerrit	Merged openstack/nova master: Allow strict_proxies for sdk Connection https://review.opendev.org/676926
18:45:13	sean-k-mooney	donnyd its the generation before intel added cluser on die
18:45:14	artom	But... it might just be faster to get FN running in CI :)
18:45:26	sean-k-mooney	but as i said 2 numa nodes is all that is needed
18:46:06	sean-k-mooney	intel is also ment to be fixing the nfv ci at some point
18:46:14	sean-k-mooney	maybe
18:46:19	donnyd	so will mine work?
18:46:23	sean-k-mooney	yep
18:46:46	artom	sean-k-mooney, let's make a bet on who gets there first, FN in CI, Intel, or stx :D
18:47:03	openstackgerrit	Matt Riedemann proposed openstack/nova master: Move live_migration test hooks under gate/ https://review.opendev.org/679251
18:47:03	openstackgerrit	Matt Riedemann proposed openstack/nova master: Rename the nova-grenade-live-migration job to nova-grenade-multinode https://review.opendev.org/678841
18:47:04	openstackgerrit	Matt Riedemann proposed openstack/nova master: Add cold migrate and resize to nova-grenade-multinode https://review.opendev.org/679210
18:47:37	mriedem	artom: you can ask them to use bluejeans during their meeting
18:48:04	artom	It's OK, I'm not dogmatic about my video conferencing solutions :D
18:48:36	sean-k-mooney	i think me testing stuff manully will be fater tehn all 3. i should start commint with my sean-mooney-ci gerrit account to confuse people
18:49:09	donnyd	I can work on it later tonight (after my real job) or tomorrow morning (before my real job)
18:49:20	openstackgerrit	Artom Lifshitz proposed openstack/nova master: Introduce live_migration_claim() https://review.opendev.org/635669

18:49:22	openstackgerrit	Artom Lifshitz proposed openstack/nova master: Deprecate CONF.workarounds.enable_numa_live_migration https://review.opendev.org/640021
18:49:23	openstackgerrit	Artom Lifshitz proposed openstack/nova master: Functional tests for NUMA live migration https://review.opendev.org/672595
18:49:23	openstackgerrit	Artom Lifshitz proposed openstack/nova master: DNM: Run LM integration tests with NUMA flavor https://review.opendev.org/678887
18:49:34	donnyd	any good docs to point me to for setup?
18:50:23	sean-k-mooney	donnyd: i can send you the command or document them in an etherpad if you like
18:50:46	sean-k-mooney	over all there is not too much that you need too do
18:50:54	sean-k-mooney	we jus tneed to know the name of the flavor
18:50:55	openstackgerrit	Matt Riedemann proposed openstack/nova master: Rename the nova-grenade-live-migration job to nova-grenade-multinode https://review.opendev.org/678841
18:50:56	openstackgerrit	Matt Riedemann proposed openstack/nova master: Add cold migrate and resize to nova-grenade-multinode https://review.opendev.org/679210
18:51:00	sean-k-mooney	and you need to add a few extra specs
18:51:06	mriedem	artom: ha just did ours
18:51:34	sean-k-mooney	and then 2 patches 1 for the project-config repo to add the new lable to nodepool and 1 to nova to add the perodic job
18:51:35	mriedem	unbelievably, the teacher didn't comment on my new fresh haircut
18:51:42	artom	mriedem, D:
18:51:56	mriedem	"oh maya nice to meet....WHO IS THIS HANDSOME DEVIL?!"
18:51:58	artom	The nerve of some people.
18:52:21	artom	Seriously. The female version of https://www.youtube.com/watch?v=4pXfHLUlZf4.
18:52:23	artom	(NFSW)
18:52:48	sean-k-mooney	see now there is plasible deniablity
18:54:18	donnyd	sure that would work great sean-k-mooney
18:54:33	donnyd	I can name things however you like
18:55:06	sean-k-mooney	we just need to know the name to put it in the project-config patch so it does not really matter
19:03:20	donnyd	have to be something like ubuntu-bionic-fn-numa
19:03:28	donnyd	centos-7-fn-numa
19:03:39	sean-k-mooney	yep
19:03:45	donnyd	something like that.. .whatever you come up with, I will just put it in FN
19:03:49	sean-k-mooney	although the ubunutu one is proably enough
19:04:18	donnyd	why not just use the label that is already there and i can fixup the flavor
19:04:26	sean-k-mooney	ubuntu-bionic-fn-numa is fine the the lable and then we need a flavor name that can be numa or whatever
19:04:27	donnyd	ubuntu-bionic-expanded
19:04:33	donnyd	ok
19:05:01	donnyd	i don't think anyone has ever scheduled a job against it
19:05:02	sean-k-mooney	donnyd: we could but other jobs are not expecting muliptle numa nodes
19:05:21	sean-k-mooney	well you also have the standard lables right
19:05:26	donnyd	other jobs don't run on it right now
19:05:33	sean-k-mooney	on FN
19:05:43	donnyd	i created a label that had 16G of memory
19:05:45	donnyd	yes
19:05:51	sean-k-mooney	oh ok
19:05:57	donnyd	look in nl02
19:06:19	donnyd	i already have a custom label that is completely unused
19:07:28	sean-k-mooney	these ones https://github.com/openstack/project-config/blob/master/nodepool/nl02.openstack.org.yaml#L330
19:07:41	donnyd	yep
19:07:49	sean-k-mooney	if you added hw:numa_nodes=2 to those it woudl work too
19:08:06	sean-k-mooney	that would be very close to how the intel ci used to run
19:08:12	donnyd	what do you mean?
19:08:20	donnyd	you mean in project-config
19:08:28	sean-k-mooney	no in your nova
19:08:32	donnyd	oh
19:08:45	donnyd	ok, so I just have to add that meta-data to the flavor
19:09:11	sean-k-mooney	openstack flavor set "hw:numa_nodes=2" "8cpu-16GBram-80GBdisk" i think
19:09:39	sean-k-mooney	not quite
19:09:53	donnyd	maybe --property
19:10:02	sean-k-mooney	openstack flavor set --property hw:numa_nodes=2 "8cpu-16GBram-80GBdisk"
19:10:09	sean-k-mooney	yep
19:11:08	donnyd	ok
19:11:10	donnyd	done
19:11:28	donnyd	but don't I have to setup something on the hypervisors or OS for NUMA to work?
19:11:39	sean-k-mooney	nope
19:11:50	donnyd	Ok, well its there
19:11:55	sean-k-mooney	you have kvm enabeld correct
19:12:01	sean-k-mooney	and netsted virt?
19:12:10	donnyd	no... .def not nested
19:12:15	sean-k-mooney	kvm is all that is required on the host
19:12:27	donnyd	but i can enable nested-virt
19:12:49	donnyd	not sure how that would tinker with other jobs
19:12:54	sean-k-mooney	ok nested virt woudl be need for use to use kvm in the guest which we would need to test pinning and numa currently
19:13:08	sean-k-mooney	the standard jobs hardcode qemu
19:13:12	sean-k-mooney	so they wont use it
19:13:18	sean-k-mooney	so they should be fine
19:13:21	donnyd	ok
19:13:32	sean-k-mooney	what os are you running by they way
