#openstack-nova - 2020-12-10
18:10:55 JamesBenson but I'll see about bumping the kernel, I've just been using what it deploys with, having tried to get it to a newer version.
18:11:32 sean-k-mooney the nested virt support signifcantly improve after kernel 4.19 so if you use it i always recommend having 4.19 and preferbly 5.1+ as you min kernel
18:12:11 sean-k-mooney JamesBenson: the hwe kernel works well for nested virt without needing the os bump
18:12:17 sean-k-mooney its 5.3 i belive
18:12:33 JamesBenson cool, have you ever tried low-latency kernels in openstack?
18:13:41 sean-k-mooney i have but my experice was tainted. i deployed with the low-latency kernel but i later found out that my system hangs which i attibuted to it was due to 3 failing dimms
18:13:45 ganso elod, bauzas, lyarwood: Hi! do you think those patches could be allowed to be backported from rocky to queens: https://review.opendev.org/c/openstack/nova/+/580720 and https://review.opendev.org/c/openstack/nova/+/583715 ?
18:14:05 sean-k-mooney JamesBenson: so i have not really looked at it fairly.
18:14:32 sean-k-mooney JamesBenson: my deployemtn is just my home test/dev cloud so its currently runing the mainline 5.9 kernel
18:15:25 sean-k-mooney i was hoping to move to the 5.10 upstream lts and do a ussuri to victoria upgrade over the holiday break but that is still tbd
18:15:40 JamesBenson okay, looks like linux-lowlatency-hwe-18.04 is 5.4.0.53.59
18:15:49 JamesBenson so maybe I'll try that out :-)
18:17:03 sean-k-mooney cool with that you wont need t o set the modeprobe paramter eitehr since its enabel by default
18:17:09 ganso elod, bauzas, lyarwood, nevermind I kind of got the answer myself by cherry-picking and seeing that queens is missing 2 other RequestSpec updates
18:17:46 sean-k-mooney ganso: we cant backport modifcation to any nova objects
18:18:07 ganso sean-k-mooney: thanks!
18:18:10 sean-k-mooney ganso: well we cant backport new fields
18:18:32 sean-k-mooney we can backport change that dont modify the serialsed format
18:20:12 sean-k-mooney ganso: you wanted this in queens
18:20:30 ganso sean-k-mooney: yes, in queens
18:20:57 ganso sean-k-mooney: since the fix requires the new field, we wouldn't be able to adapt it to queens, as I understand
18:22:09 sean-k-mooney that is correct unfortunetly however we coudl do something else possibly
18:22:33 sean-k-mooney if the places that need is_bfv hae a context and instnace tehy could use is_volume_backed_instance(ctxt, instance) instead directly
18:24:28 ganso sean-k-mooney: hmmm I will investigate this in the code. Thanks! Although, I'm aware it would make the backport with new code with extra risk, and then the stable maintainers may disagree with merging it
18:24:56 sean-k-mooney yes you would basically have to modeify https://review.opendev.org/c/openstack/nova/+/580720/6/nova/scheduler/utils.py
18:25:26 sean-k-mooney unfortunetly that does not have th instance or a keystone context
18:25:40 ganso oh I see
18:25:44 ganso yea, bummer
18:25:56 ganso thanks again sean-k-mooney ! =)
19:44:54 melwitt gibi, lyarwood: yes I can take over babysitting those patches once yall are gone
20:10:25 openstackgerrit Lance Bragstad proposed openstack/placement master: Implement secure RBAC for resource providers https://review.opendev.org/c/openstack/placement/+/760240
21:21:33 JamesBenson sean-k-mooney, one follow up question. Is there a setting (or benefit) to passing all of the CPU flags in the nova.conf?
21:50:29 lyarwood elod: https://review.opendev.org/q/I8f24b839bf42e2fb9803dc7df3a30ae20cf264eb lets see what that breaks
21:50:56 lyarwood melwitt: ack sorry had already gone, just wanted to check on the bandit thing and it looks like we might be able to get away with backporting the above to workaround it
21:53:01 melwitt lyarwood: is there a bug link for the bandit thing? sorry I fell too far behind with knowing what was going on there
21:55:14 openstack Launchpad bug 1907438 in OpenStack Object Storage (swift) "ERROR: Package 'bandit' requires a different Python: 2.7.17 not in '>=3.5'" [Undecided,Confirmed]
21:55:14 lyarwood melwitt: http://lists.openstack.org/pipermail/openstack-discuss/2020-December/019292.html and https://bugs.launchpad.net/nova/+bug/1907438
21:55:45 melwitt ah thanks
21:55:56 melwitt I don't know how I missed that on the ML
21:56:15 lyarwood there's so many fires at the moment, I wouldn't worry about it :)
21:56:27 melwitt you can say that again
21:56:30 lyarwood there's so many fires at the moment, I wouldn't worry about it :)
21:56:49 melwitt last night I almost tweeted "openstack ci right now is" with a mushroom cloud gif
21:56:58 melwitt hah xD
21:57:48 melwitt or the gif of elmo with the fire behind him
21:59:57 lyarwood hehe yeah both would still work right now :D
22:00:16 lyarwood ah cool the stable/victoria LC change made it to the gate
22:00:55 melwitt hot dog!
22:06:29 melwitt lyarwood: hm something I don't get though is how the LC change is having nova-multi-cell as non-voting if the disable voting change isn't in the gate?
22:08:31 lyarwood melwitt: different branches, I wrote the LC change switching nova-multi-cell to non-voting before gibi pushed his master change
22:09:03 lyarwood melwitt: I was going to pull it out and backport squash his into the stable/victoria LC fix but he said to just go on with the non-voting change
22:10:09 lyarwood melwitt: either way it's only to allow the LC change to land in stable/victoria, we will need to follow up once it's in
22:10:24 melwitt lyarwood: yeah but https://review.opendev.org/c/openstack/nova/+/766440 isn't approved? maybe I'm just missing something dumb
22:11:02 melwitt oh you squashed it. sorry /facepalm
22:11:02 lyarwood melwitt: oh I need to close that, I squashed that into the actual LC change, that's an old PS that isn't used anymore
22:11:10 melwitt yeah I see now. guhhhhh
22:11:19 lyarwood yeah sorry I've got dead changes all over the place from the last few days
22:11:32 melwitt no it's not your fault that I can't see things :)
22:12:57 melwitt ok, so iiuc we'll do this and then after gibi's change lands, we need to backport it to stable/victoria, then we re-enable voting
22:14:01 lyarwood yeah I think so
22:14:40 lyarwood okay bed time for me now, good luck with the gate :D
22:15:55 melwitt ok cool, gnight o/
22:17:45 melwitt argh nova-ceph-multistore failed in the gate queue. of course it did
#openstack-nova - 2020-12-11
00:40:41 brinzhang gmann: ack, that's what I did, just change the List Security Groups By Server API, dont change the deprecated apis.
00:40:44 brinzhang gmann: thanks
00:41:07 gmann brinzhang: +1, I will check your patches tomorrow.
00:42:32 brinzhang gmann: yeah, thanks, I have to add the needed unit tests, then submit it, and add you as a reviewer
00:42:57 gmann cool
06:59:02 openstackgerrit zhulipeng proposed openstack/nova stable/pike: Fixed multipath residue when evacuating the VM https://review.opendev.org/c/openstack/nova/+/766675
08:05:13 gibi good morning
08:06:53 gibi melwitt: thanks for the babysitt
08:08:59 gibi I see we were not lucky so far
08:27:19 bauzas gibi: good morning
08:29:16 gibi bauzas: o/
09:02:33 gibi https://review.opendev.org/c/openstack/nova/+/765749 is in the gate queue (again), fingers crossed
09:52:04 elod lyarwood: thanks for those backports \o/ we'll see whether everything is happy with it :) so there are now 3 possible solution for the bandit issue, so hopefully it'll be sorted out soon!
09:53:28 elod lyarwood: btw, I'm kinda @ PTO today and monday, but I'll be here time to time and try to look at things
11:22:58 hemanth_n Hi Nova team, can i get reviews on ussuri backport https://review.opendev.org/c/openstack/nova/+/761701 (Had initial review from elod with +2)
11:25:44 lyarwood hemanth_n: ack will look shortly
11:26:46 hemanth_n lyarwood: thanks
11:28:45 gibi lyarwood: https://review.opendev.org/c/openstack/nova/+/765749 bounced from the gate again
11:29:23 gibi with the grande job failing on test_live_block_migration_paused
11:37:50 openstackgerrit Kashyap Chamarthy proposed openstack/nova-specs master: Re-propose "Secure Boot support for KVM & QEMU guests" for Wallaby https://review.opendev.org/c/openstack/nova-specs/+/759731
11:38:25 kashyap gibi: stephenfin: --^ Addressed the small comments from PTG and review (adding the bit about traits; and adjusting version info, and couple of minor bits)
11:39:30 kashyap (Cc: Sean, Bauzas. Previous reviewers :-))
11:39:38 lyarwood gibi: gah, that's still on bionic iirc,
11:39:58 lyarwood gibi: iirc I had see quite a few failures recently like that on master, I'll write up an ER query shortly and check
11:45:27 sean-k-mooney yep test_live_block_migration_paused has been failing on master
11:46:01 lyarwood just in the grenade job however right?
11:46:07 lyarwood I don't think the focal job is hitting this
11:46:12 sean-k-mooney yes i think so
11:46:48 lyarwood hemanth_n: https://review.opendev.org/c/openstack/nova/+/761701 LGTM but the gate is blocked at the moment, I'm going to +2 and follow up with a +W once it's working again
11:47:03 sean-k-mooney lyarwood: did you see my review comments
11:47:16 lyarwood sean-k-mooney: nope
11:47:31 sean-k-mooney lyarwood: it looks fine but i think it would be cleaner to pull in the two missing trivial refactor patches
11:47:45 lyarwood sean-k-mooney: ack, I can help with that
11:48:06 hemanth_n sean-k-mooney: do you want them backport separately or as part of this patch
11:48:33 sean-k-mooney hemanth_n: seperatly
11:48:43 sean-k-mooney https://github.com/openstack/nova/commit/17ba10b75961ef667e45b9dedbac34212a7e7e9b and https://github.com/openstack/nova/commit/0ab8a03c782851d4019c90e6159bd1f83c0658e6
11:48:53 sean-k-mooney well as in as seperate patches
