14:02:14 <tdurakov> hi folks
14:02:19 <pkoniszewski> o/
14:02:24 <tdurakov> agenda https://wiki.openstack.org/wiki/Meetings/NovaLiveMigration
14:02:28 <markus_z> o/
14:02:35 <tdurakov> let's start
14:02:43 <tdurakov> #topic CI
14:02:48 <davidgiluk> o/
14:02:58 <tdurakov> so, serial console hook for live migration
14:03:11 <tdurakov> markus_z: what options do you want to propose?
14:03:49 <markus_z> I have 5 possibilities identified for https://review.openstack.org/#/c/347471/39
14:04:11 <markus_z> ocata->ocata is working, newton->ocata is *not* working
14:04:11 <tdurakov> markus_z: share them with us, please
14:04:19 <markus_z> proposal 1: let the grenade job read: nova/nova/tests/live_migration/hooks/run_tests_grenade.sh
14:04:19 <tdurakov> right
14:04:24 <markus_z> proposal 2: have a "ignore-test-cases"-regex env variable only written by the grenade job
14:04:29 <markus_z> proposal 3: have a check in tempest which checks the oldest release
14:04:33 <markus_z> proposal 4: wait for the backports
14:04:37 <markus_z> proposal 5: wait for next release cut-off to merge the new tests
14:04:49 <markus_z> That's the copy&paste of what I prepared
14:04:58 <tdurakov> ok
14:05:45 <tdurakov> tbh, I like an idea proposed by pkoniszewski
14:05:45 <markus_z> The "issue" is that both jobs "normal l-m" + "grenade l-m" trigger the same "run_tests.sh".
14:05:58 <markus_z> Which one was that again?
14:05:59 <tdurakov> to identify that it's a grenade job and skip tests
14:06:22 <tdurakov> once we backport all patches required - just remove a check
14:06:46 <markus_z> uh, even better, I like that
14:07:01 <pkoniszewski> yeah, +1 to that
14:07:10 <markus_z> It would be then just a conditional check in run_tests.sh ?
14:07:15 <pkoniszewski> or we can just push backports forward
14:07:26 <tdurakov> I'd not wait for backports
14:07:44 <tdurakov> I mean there are several patches on review for serial console
14:07:58 <pkoniszewski> does it really matter when the serial console hook will be merged?
14:08:00 <tdurakov> and it would be great them to be tested asap
14:08:23 <pkoniszewski> i mean, do we need to have it in a week or two?
14:08:24 <markus_z> pkoniszewski: Not necessarily, but that problem will come again, I think
14:09:23 <tdurakov> if we decide to add check to skip these tests for grenade, there are 2 variables: BRANCH_OVERRIDE and  DEVSTACK_GATE_GRENADE that will help to identify that we are in grenade job
14:09:23 <markus_z> tonyb is already a little hesitant to the backports, they are not easy stuff
14:09:47 <pkoniszewski> they aren't, that's true
14:10:19 <pkoniszewski> so, i'm okay with the proposal and i'm gonna support it
14:10:29 <tdurakov> I'll prepare test to identify that that theory will work
14:10:33 <markus_z> +1
14:10:40 <tdurakov> if so will update markus_z patch
14:10:49 <markus_z> thanks a lot
14:11:43 <tdurakov> it's not a big deal
14:12:09 <tdurakov> if it won't work we need another workaround, but let's check it first
14:12:41 <tdurakov> markus_z, pkoniszewski thanks for pushing that!
14:13:21 <tdurakov> #topic bugs
14:13:38 <tdurakov> last week faced wih a bug https://bugs.launchpad.net/nova/+bug/1647451
14:13:38 <openstack> Launchpad bug 1647451 in OpenStack Compute (nova) "Post live migration step could fail due to auth errors" [Medium,In progress] - Assigned to Timofey Durakov (tdurakov)
14:13:51 <tdurakov> review is very welcome
14:14:37 <tdurakov> and fyi, there is a bp https://blueprints.launchpad.net/nova/+spec/use-service-tokens for the same things
14:15:02 <tdurakov> but I think it's worth to fix a bug anyway, because we need it to be backported
14:15:26 <tdurakov> thoughts on that?
14:15:39 <tdurakov> johnthetubaguy: ^
14:20:39 <tdurakov> do we have anything to discuss?
14:22:25 <tdurakov> markus_z: https://review.openstack.org/#/c/407532/
14:22:46 <tdurakov> looks like there is nothing else for today, thanks for participating
