16:14:38 bauzas #info As a reminder, people eager to review changes can +1 to indicate their interest, +2 for asking cores to also review
16:15:00 bauzas I said I was about to propose a Gerrit dashboard for those, I had no time yet to do it
16:15:08 bauzas #action bauzas to propose a Gerrit dash
16:15:15 bauzas #topic Stable Branches
16:15:20 bauzas elodilles: ?
16:15:24 elodilles yepp
16:15:32 elodilles i'm not aware of any gate issue
16:15:41 elodilles otherwise nothing else to report
16:15:48 elodilles #info stable branch status / gate failures tracking etherpad: https://etherpad.opendev.org/p/nova-stable-branch-ci
16:16:09 elodilles please add stable gate issues if you see any ^^^
16:16:14 bauzas ++
16:16:22 elodilles that's all from me
16:17:19 bauzas cool
16:19:19 bauzas #topic Open discussion
16:19:24 bauzas (bauzas) Specless blueprint approval for https://blueprints.launchpad.net/nova/+spec/aggregatemultitenancyisolation-to-support-unlimited-tenant
16:20:23 sean-k-mooney hum
16:20:42 bauzas wdyt about that ?
16:21:06 sean-k-mooney dont we support having multiple keys
16:21:18 sean-k-mooney so i didnt think there was an effective limit today
16:22:46 sean-k-mooney or parhaps we require one aggreate per tenatnt today i would have to review the code
16:23:10 sean-k-mooney the patch is basiclly enabling what i orgianlly tought already worked
16:23:22 sean-k-mooney instead of looking for filter_tenant_id explictly
16:23:28 sean-k-mooney just making that a prefix
16:24:00 sean-k-mooney so you can have filter_tenant_id=<tenant-0> filter_tenant_id_1=<tenant-1>
16:24:30 sean-k-mooney thats proably an ok change to make
16:25:35 sean-k-mooney tenant isolation shoudl be done via placement
16:25:45 sean-k-mooney and we shoudl really be removing the filter based approch so im not sure
16:27:16 bauzas sahid wanted to still use the filters
16:27:53 sean-k-mooney i would be in favor of deprecateding it for removal in D if the current fucntionlaiy is supproted by the placment approch
16:28:41 sean-k-mooney https://docs.openstack.org/nova/latest/admin/aggregates.html#tenant-isolation-with-placement
16:28:47 dansmith tenant isolation can't be done entirely in placement right?
16:28:55 bauzas I think sahid actually wanted to backport this
16:28:57 sean-k-mooney i belive it can
16:29:02 dansmith all we can do is select an aggregate and then get placement to limit for us
16:29:14 bauzas you know what ? we can punt this until he can be around
16:29:33 sean-k-mooney so given this dicussion i would say not a specless blueprint
16:29:40 sean-k-mooney spec or ptg discussion
16:29:41 dansmith right
16:30:48 sean-k-mooney i think the fucntionaliyt is possible today withthe placement approch so i would question why we dont remove the filter
16:30:59 sean-k-mooney so i would like to capture the answer to that
16:31:51 bauzas okay, let's say this
16:31:57 bauzas I'll tell this to sahid tomorrow
16:32:12 bauzas and he could explain why he still wants to use filters
16:32:20 bauzas (IMHO like I said, backports)
16:32:39 bauzas do all agree ?
16:32:44 sean-k-mooney backports are a downstream problem
16:33:01 bauzas sure, but this is easier with a python module like a filter, right?.
16:33:03 sean-k-mooney that is not a good reason to extend it upstream unless its useful upstream
16:33:21 bauzas sure, we need to discuss the usecases
16:33:33 bauzas but I'm not in favor of removing every single filter we have
16:33:44 bauzas some operators still run filters on their choices
16:33:44 dansmith agree
16:34:17 bauzas anyway, let's punt this until PTG or when sahid can join us
16:34:26 dansmith we have the prefilter for isolation, which uses placement's aggregates to do some isolation, but I'll have to revisit my understanding of the differences
16:34:31 bauzas #agreed defer this agreement to the next PTG
16:34:49 bauzas I'll add a topic in the PTG etherpad
16:34:55 sean-k-mooney dansmith: we deveoped that prefilter to eventurlly remove this one
16:36:07 sean-k-mooney https://specs.openstack.org/openstack/nova-specs/specs/rocky/implemented/placement-req-filter.html#proposed-change
16:36:43 bauzas sean-k-mooney: well, for CPUFilter, I totally agree with removing it
16:36:47 sean-k-mooney this was the first prefilter that you wote many moons ago
16:37:24 bauzas I'm just saying that for non-allocatable filters (placing things) we may leave those if those are cheap to maintain
16:37:41 sean-k-mooney right but this filter is know to be problematic
16:37:42 bauzas because this is a python module and not another SQL query
16:37:54 sean-k-mooney so i realy dont think this is a good example ot extned
16:37:55 dansmith sean-k-mooney: I know, but I think there were limitations
16:38:18 bauzas anyway, we punted the potential agreement to the next PTG
16:38:21 dansmith I thought we agreed to punt until PTG ?
16:38:22 dansmith yeah
16:38:30 bauzas so let's stop for now
16:38:40 bauzas and I'll give you all extra 20 mins of your time
16:38:40 sean-k-mooney sure
16:38:42 bauzas thanks all
16:38:52 bauzas any other item before we close ?
16:39:07 sean-k-mooney i just wanted to highlight i reporposed the healtcheck spec https://review.opendev.org/c/openstack/nova-specs/+/897225
16:39:16 bauzas oh right, I've seen it
16:39:20 sean-k-mooney so if we can reappove that it would be good
16:39:22 bauzas I just need to look at it
16:39:25 sean-k-mooney ack
16:39:41 sean-k-mooney thats all from me
16:39:43 bauzas tuesdays are usually upstream days for me, but I was vamped into some crazy internal thing
16:39:57 bauzas anyway, ending now
16:40:00 bauzas thanks all

16:40:33 sean-k-mooney bauzas: if your looking at repoposals then https://review.opendev.org/c/openstack/nova-specs/+/895924 would be alos nice to look at
16:40:46 bauzas yeah I need to do reviews
16:40:59 bauzas my gerrit nova-specs dashboard misses me
16:42:13 opendevreview Dan Smith proposed openstack/nova master: WIP: Compile mdev samples for nova-next https://review.opendev.org/c/openstack/nova/+/897708
16:42:24 dansmith okay locally mtty.ko gets built and inserted during devstack
16:43:58 bauzas <3
16:44:47 bauzas if I have time tomorrow, I'll work on a nova WIP to change the libvirt driver to use a specific 'virtual' device for mtty
16:45:02 bauzas so we shall be able to test
