Any update? 14:09:25 doesn't work as in silently ignores the sev requirement or blows up? 14:09:36 I think "guest won't boot" 14:09:43 doesn't ignore the sev requirement - that was the first thing I asked. 14:09:44 If it's the thing I'm thinking of, causes the guest OS to crash 14:09:56 the IOMMU stuff? 14:10:04 will libvirt raise an error trying to start the guest? 14:10:11 or you just have a running domain that is busted? 14:10:13 (thanks dansmith) 14:10:13 #action dansmith to propose db migration placeholders 14:10:14 unfortunately no 14:10:24 at least not from reading aspiers' comments 14:10:27 great 14:10:46 if it doesn't make train, there should be a known issue release note and a big fat warning in the docs 14:11:14 "DO NOT USE IS BROKE" 14:11:20 that ought to do the trick 14:11:37 yes, good point, we should propose a patch for ^ and put it under the fix. 14:11:57 well, 14:12:08 are you going to revert that if the fix lands? reverting release notes is kind of weird. 14:12:11 git history wise 14:12:21 i'd say don't put them in the same series, make them separate alternatives 14:12:30 fair 14:12:49 i might even suggest putting an asterisk in the prelude next to the sev thing 14:12:59 like barry bonds trying to get into the hall of fame 14:13:13 because really, 14:13:27 * stephenfin wonders who this Barry Bonds fellow is 14:13:44 because if there are issues like this, e.g. combinations of things breaks the guest, what other unknowns are there? 14:14:17 That's kind of true of any significant new feature though 14:14:27 at least we found this corner case ahead of release 14:14:31 yeah, if we never had any bugs, what would we do with our day? 14:14:38 the difference is, 14:14:46 if you think you're getting a secure vm and it's not 14:14:55 meaning the potential for CVEs from using this are higher 14:14:59 than any other random old feature 14:15:01 right? 14:15:01 right, and that's not what happens 14:15:06 in this case... 14:15:44 anyway, would be cool if the sev minded people can get that fix done so it's not something we need to document as a known issue to begin with 14:15:56 i realize they are prioritizing backporting it to rocky... 14:16:03 Again with the caveat that I don't understand this stuff deeply, I picked up from aspiers that that (lying about SEV being on) is not a thing that can happen. 14:16:50 anyway 14:17:57 o, stephenfin just volunteered (in -nova) to 14:17:57 #action stephenfin draft the SEV bug warning patch 14:17:57 thanks stephenfin 14:18:01 moving on. 14:19:28 any other RC potential items? 14:19:35 if you think of something, update https://etherpad.openstack.org/p/nova-train-release-todo please 14:19:57 #topic Summit/PTG Planning 14:20:59 Since many will not be in Shanghai, I'm going to try to do virtual ptg discussions via email, as much ahead of the ptg as possible. 14:21:22 one such discussion: 14:21:22 Ussuri scope containment 14:21:22 #link start of thread http://lists.openstack.org/pipermail/openstack-discuss/2019-September/thread.html#9832 14:21:22 #link continued http://lists.openstack.org/pipermail/openstack-discuss/2019-October/thread.html#9835 14:21:22 #link Spec template update for "core liaison" https://review.opendev.org/#/c/685857/ 14:22:25 There seems to be at least vague general not-opposition to the core liaison thing. I'm going to update the spec template patch as soon as we're done here per mriedem's catch 14:22:41 we have a couple merged already, 14:22:47 yes 14:22:49 and at least one almost ready to be merged 14:22:57 * dansmith selfishly states 14:23:07 I'd like to get those filled in 14:23:11 so if we merge that we'll just edit those? 14:23:16 yes 14:23:33 and if we can't find liaisons for already approved things we'll just un-approve them? 14:23:43 I'm going to propose those edits in the same patch with placeholders for now so I can take the optional-ness out of the checker. 14:23:50 and in my spec's case, I just put myself as the sponsor? 14:23:51 mriedem: that seems reasonable, yes. 14:24:06 dansmith: you can mark me as a sponsor if it means anything 14:24:07 or do you want me to try to find someone else if possible? 14:24:23 dansmith: yes, unless anyone thinks the "cores (and experienced nova devs) can be their own sponsor" thing is a bad idea 14:24:25 mriedem: ack, I'm happy to do whatever the desired convention is 14:24:39 sorry, dansmith that was "yes, you can sponsor yourself" 14:24:51 efried: it really just means that I'm owning the "I know who to poke for reviews" tenet of your hypothesis right? 14:25:11 yes, and the "I know what it means for my code to be ready for reviews" 14:25:12 that's my understanding 14:25:17 and other cultural arcana 14:25:18 roger 14:25:22 i retract my sponsorship offer 14:25:25 hah 14:25:42 we should have like a, 14:25:49 I hope there is a limit of one core sponsor per cycle, so this can be my only one 14:25:55 thing that says "if you're a core and approve this spec, you are a bad person if you don't review it" thing 14:25:58 (not really) 14:26:01 I recognize this is mostly noise for core-proposed features; it's there more for the "outsiders". 14:26:16 efried: I know, which is why I asked so I can set the proper example 14:26:38 ack 14:27:21 did you want t discuss this proposal now? 14:27:35 or just mention it in the realm of vPTG discussions? 14:27:52 we can discuss if there's discussion needed, or we can do that in the review, up to y'all 14:28:24 the other "scope containment" issue is more controversial. 14:29:15 First, I apologize if any of my responses have come across as belligerent or sarcastic, I'm really really trying not to do that, trying to keep everything reasonable. 14:29:49 i haven't taken it that way fwiw 14:30:19 I recognize my bid of 25 (now 30) and the reasoning behind it was way simplistic. 14:30:46 ack, it's hard for me to detach the core sponsorship thing from the throttling, but if we call it liaison per your description here, and then potentially use that in throttling then it makes sense to push forward on this regardless of the throttling 14:31:09 * dansmith said throttling a lot in that 14:31:15 note that a) it's just a first stab, please let's discuss and try to refine, but also b) I was deliberately trying to avoid delving too much into the whys and wherefores because imo those discussions can't possible end well 14:31:20 heh, dansmith and throttling 14:32:35 i think the sponsorship thing makes sense and has happened implicitly in some cases, e.g. me and several of brinzhang's api changes in train 14:32:58 I'm OK with the sponsorsip thing as well as the proposed ~30is limit 14:33:28 does the bps will be selected first come first served basis? 14:33:48 that is something i have been wondering 14:33:52 I mean from those bps that are qualify 14:34:02 that's my primary complaint about choosing a number, 14:34:16 that choosing a number requires more oversight and planning than "the first 25 to apply" 14:34:18 it kind of punishes people that are new to nova 14:34:23 gibi: tbd, but I was thinking not. 14:34:44 I was thinking we trim at/after spec freeze 14:34:48 because if that's the case, then we're going to be doing accelerators and a bunch of trivial things in U :) 14:34:54 well, first 25 to actually get approved with a sponsor if they aren't core-driven 14:35:10 first served are usually things that are previously approved, 14:35:23 and in that respect i think it's fair for them to get a bit more priority / attention 14:35:35 i.e. finish the old debt before taking on new debt 14:35:44 do we have a sense for how many items form train we will cary over 14:35:58 like cyborg integration come to mind 14:36:02 we have two major ones already in the tree 14:36:08 cyborg and cross-cell-resize 14:36:08 the 2 big ones are cyborg and cross cell resize 14:36:08 Yeah, fwiw, when I was mulling this idea originally, I was going to propose "hard limit of $N where first dibs are previously approved, second dibs are previously proposed but not approved in train" 14:36:39 the blueprints for spot instances and rebuild from cell0 are candidates but i'm pretty sure cern has given up on upstreaming those 14:36:44 after 2-3 releases 14:36:46 efried: note that previously approved in a cycle where we had no core sponsorship seems unfair, so you mean "previously approved and where there's a sponsor" right? 14:36:52 * gibi wants to finish live migration, evacuate, unshelve with bandwidth 14:37:06 gibi: commence to spec'ing :) 14:37:14 dansmith: Right, the above was before I had the core sponsor concept in mind. 14:37:21 gibi: you are not the only one that whats those so i hope they happen too 14:37:31 mriedem: sure, sure 14:37:41 fwiw things deferred from train are here https://blueprints.launchpad.net/nova/ussuri 14:37:51 at this point, even previously-approved should have core sponsor (which is why the already-merged ones need to be updated) 14:38:19 *though not all things targeted at ussuri were approved in train, maybe just discussed at length 14:38:36 well i thin mriedem quifies for cross cell 14:38:37 As usual, we don't auto-approve a deferred thing unless someone reproposes it 14:38:54 yup so spot instances takes care of itself i guess 14:38:55 efried: and i assume you would sponcer cyborg 14:39:10 maybe we should get out of the weeds and save the details for -nova 14:39:14 Several of those deferred things were non-core-ish where they just got zero action in train ("developer walked away" category) 14:40:03 Cool, I'll just bring it back to: Please let's continue discussing ways to put a concrete cap on the amount of feature work in ussuri, in a way that's simple to understand and implement. 14:40:19 #topic Stable branch status 14:40:19 #link stable/train: https://review.openstack.org/#/q/status:open+(project:openstack/os-vif+OR+project:openstack/python-novaclient+OR+project:openstack/nova)+branch:stable/train 14:40:19 #link stable/stein: https://review.openstack.org/#/q/status:open+(project:openstack/os-vif+OR+project:openstack/python-novaclient+OR+project:openstack/nova)+branch:stable/stein 14:40:19 #link stable/rocky: https://review.openstack.org/#/q/status:open+(project:openstack/os-vif+OR+project:openstack/python-novaclient+OR+project:openstack/nova)+branch:stable/rocky 14:40:19 #link stable/queens: https://review.openstack.org/#/q/status:open+(project:openstack/os-vif+OR+project:openstack/python-novaclient+OR+project:openstack/nova)+branch:stable/queens 14:40:27 i've got a release request up for stein, 14:40:34 https://review.opendev.org/#/c/686301/ 14:40:43 need to work on some more rocky and queens reviews 14:41:03 though many are my backports so... 14:41:06 help 14:41:18 mriedem: stein release request ready to go at this point? 14:41:21 yes 14:41:24 I've been trying to suck a little less lately 14:41:26 updated the hash this morning 14:41:34 dansmith: it's appreciated 14:41:40 I see three stein patches with a +2 on them, we're good leaving those behind for now 14:41:42 ? 14:41:43 even if i don't say so 14:41:59 mriedem: wouldn't hurt to send me flowers occasionally, baby 14:41:59 one of those has a -1 14:42:02 or 2 -1s 14:42:08 the others are low priority 14:42:17 cool 14:42:21 dansmith: laura first if any :/ 14:42:25 I'll review the release patch fwiw 14:42:27 * mriedem is a bad partner 14:42:29 yeah the +2d -1ed one is hard to filter out 14:43:05 #topic Bugs (stuck/critical) 14:43:05 No Critical bugs 14:43:05 #link 74 new untriaged bugs (+2 since the last meeting): https://bugs.launchpad.net/nova/+bugs?search=Search&field.status=New 14:43:05 #link 3 untagged untriaged bugs (-1 since the last meeting): https://bugs.launchpad.net/nova/+bugs?field.tag=-*&field.status%3Alist=NEW 14:43:05 Any bug discussions we didn't already have?

14:49:35 Yeah, probably. I killed a lot of stuck 14:49:37 *stuff 14:49:43 the review status score drop 14:49:48 thanks for that 14:49:50 yup 14:49:53 np 14:50:07 #topic Open discussion 14:50:12 One item on the agenda: 14:50:20 #help Volunteer needed to update the contributor guide (see https://review.opendev.org/#/c/685630/ 14:50:53 I'll do it 14:51:04 I thought bauzas has something similar at one point 14:51:18 but I don't see conflicts so maybe not 14:51:23 takashin proposed the usual s/$old/$new/ patch, but it seemed like we would be better off leaving it known-stale considering how stale the surrounding content is. 14:51:30 #action stephenfin to update the contributor guide 14:51:32 thanks again stephenfin 14:51:36 In case you didn't refresh, I added something to that list too of open discussion too 14:51:36 you're a champ 14:51:42 aww, shucks 14:51:52 ah, thanks, no I hadn't refreshed 14:52:12 Specless BP approval 14:52:12 #link nova-net diaf blueprint https://blueprints.launchpad.net/nova/+spec/remove-nova-network-ussuri 14:52:29 yes? 14:52:33 so, do we not need core sponsorship for something like that? 14:52:40 stephenfin can sponsor self. 14:52:50 specless BP too 14:52:53 well, what I mean is, does that count in the quota 14:52:55 I mean, I can submit a spec 14:52:58 question is, if we approve the bp now, and then later decide it falls "below the line", do we get to unapprove it? 14:53:00 stephenfin: I know, that's why I'm asking 14:53:15 but it'll just be this https://img.memecdn.com/delete-all-the-things_o_4994465.jpg 14:53:16 we do'nt need a spec for that, it was approved before as specless, it's mostly mechanical work, 14:53:22 i think it should count toward quota 14:53:27 it will definitely be a time sink 14:53:30 efried: right, because if I'm picking priority, I put that lower than some other things we might be planning inside a small envelope 14:53:41 mriedem: yep, that's what I'm asking about 14:54:03 i think its still valuable to pay down that debt 14:54:11 yeah i think it's still worth doing 14:54:14 even with the new cap 14:54:15 of course 14:54:29 we also don't know what all is going to be on the table on Feb 13th 14:54:33 I'd like to see us doing tech debt work along with feature work 14:54:43 ...and it looks like I'm not alone. phew 14:54:44 so I think we should approve it now 14:54:52 i'm +1 on approval 14:55:14 Which reminds me - that SRIOV live migration conversion to use resources claims that came up during NUMA LM review - what do we think, specles blueprint? 14:55:50 i think you and i should proably scope it and then make that determination once we have 14:55:57 how about we get the numa live migratoin functional test stack landed first.. 14:56:24 (done, specless bp approval.) 14:56:25 mriedem, well, yes, but we were talking about U tech debt :) 14:56:26 i.e. finish what was started rather than starting new 14:56:34 yes also i would like to land the periodic tempet job first too 14:56:52 artom: and i'm saying don't even bring it up until the func tests are done 14:57:04 mriedem, fair enough 14:57:51 remember we talked about backporting those to train, 14:57:57 the longer that stalls the harder that backport will be, 14:58:08 especially with stephenfin on a func test rip up rampage for nova-net 14:58:18 rm -rf * 14:58:37 i think we are aiming to finish the migration stuff before m1 14:58:50 let's end this god forsaken meeting 14:58:52 e.g. the fucntioal test and temepest 14:59:24 y, sounds like there's more discussion to be had, artom & sean-k-mooney continue in -nova? 14:59:26 sean-k-mooney: money talks and all that 14:59:48 Thanks all. 14:59:48 o/ 14:59:48 #endmeeting
