15:20:50 cfriesen_ mriedem: so basically we need to quiesce the guest before detaching a cinder volume?
15:23:56 openstackgerrit Alex Szarka proposed openstack/nova master: Transform instance-live_migration_abort notification https://review.openstack.org/420453
15:24:29 mriedem cfriesen_: i think the only time we quiece the guest when a volume is attached is when taking a snapshot
15:25:11 cfriesen_ mriedem: I mean that more generally, like having the end user shut things down in the guest.
15:26:08 mriedem oh
15:26:15 mriedem does nova fail or just hang?
15:26:18 mriedem nova/os-brick
15:27:05 cfriesen_ mriedem: nova tries 7 times to detach the device and then gives up
15:27:54 cfriesen_ mriedem: not sure if nova returns an error or if heat ignores it
15:28:44 mriedem oh, well, it's a cast
15:28:49 mriedem so it's all async from a heat pov
15:29:00 mriedem so heat would have to timeout waiting for the volume to be detached
15:30:40 cfriesen_ mriedem: it's kind of too bad we can't do an unclean teardown if we're going to be deleting everything anyway
15:32:16 openstackgerrit Alex Szarka proposed openstack/nova master: Transform instance.resize.error notifications https://review.openstack.org/417882
15:39:25 bauzas jaypipes: just a rebase for https://review.openstack.org/#/c/469037/ given you already +2d it
15:39:44 bauzas mriedem: dansmith: possibly some others could look at it ^
15:40:11 openstackgerrit Sylvain Bauza proposed openstack/nova master: Fix ChanceScheduler returning a wrong node https://review.openstack.org/466725
15:41:08 jaypipes bauzas: done
15:41:30 bauzas cools
15:45:23 openstackgerrit Ildiko Vancsa proposed openstack/nova master: WIP/POC Implement new attach Cinder flow https://review.openstack.org/330285
15:49:07 mkucia Hi! I wonder if someone know what is the story behind `PCI device pools` in nova. Were those introduced for performance reasons? Why not plain list of devices?
15:51:22 cfriesen_ andreykurilin: are you around?
15:51:54 andreykurilin cfriesen_: hi! a bit (will need to go in 10 minutes)
15:57:15 cfriesen_ andreykurilin: about https://review.openstack.org/#/c/435141/, if I move the test into functional/v2/legacy/test_servers,py, it seems like those would run with the 2.1 API version, not 2.47
15:57:46 cfriesen_ andreykurilin: did you want me to copy it to the legacy tests so it gets run in both places?
15:58:40 andreykurilin cfriesen_: you can create a base class in the legacy module and inherit from it in your new TestCase
16:00:03 cfriesen_ andreykurilin: you're thinking a new base class with just the one test?
16:00:11 andreykurilin yup
16:00:23 cfriesen_ andreykurilin: okay, can try that
16:01:01 sfinucan gibi, Kevin_Zheng: I assume [1] needs to be rebased to work with [2] now? [1] https://review.openstack.org/#/c/459493/ [2] https://review.openstack.org/#/c/463001/
16:01:39 sfinucan mkucia: I should know that. Lemme dig out notes
16:03:14 mkucia sfinucan: That would be great, thanks!
16:06:44 openstackgerrit Rodolfo Alonso Hernandez proposed openstack/os-vif master: [WIP] Add abstract OVSDB API https://review.openstack.org/476612
16:06:57 sfinucan mkucia: Looks to be something to do with performance
16:07:02 sfinucan https://github.com/openstack/nova/blob/master/nova/pci/stats.py#L39-L44
16:07:23 sfinucan bauzas, jaypipes or sean-k-mooney might be able to offer more info, but that would be my guess
16:07:55 sfinucan What's that now, ralonsoh? ;)
16:08:06 jaypipes mkucia: pci device pools are stupid, IMHO. they need to be killed off.
16:08:14 mkucia I see. Thanks for the tip on the people.
16:09:11 mkucia jaypipes: Agree, there are a frew things in nova PCI handling that seems a bit off.
16:09:25 sfinucan mkucia: Careful - you'll set him off ;)
16:09:35 mkucia :O
16:09:50 sfinucan (jaypipes is a not a fan of the PCI or NUMA code in nova, heh)
16:11:04 jaypipes bauzas, dansmith, mriedem: speaking of PCI devices... this would be great to get in. https://review.openstack.org/#/c/469147/
16:12:16 ralonsoh sfinucan: hey
16:12:38 ralonsoh sfinucan: you mean https://review.openstack.org/476612?
16:15:06 sfinucan ralonsoh: Indeed
16:15:13 sfinucan Good to see. I'll keep an eye on that
16:15:56 ralonsoh sfinucan: perfect! This is a WIP. Then I'll need to: 1) add unit tests, 2) add native implementation and 3) probably add functional tests
16:16:02 sfinucan I was trying to something kind of similar with the linux-bridge stuff, but got annoyed by how "porcelain'y" pyroute2 is (https://review.openstack.org/#/c/451433/)
16:16:21 sfinucan ralonsoh: Sounds like a plan to me. I assume we can kill the non-native version then?
16:16:52 ralonsoh sfinucan: we'll keep both (for Windows) and configurable via conf file
16:16:58 ralonsoh sfinucan: like in Neutron
16:17:18 sfinucan Ah, Windows. Gotcha
16:17:26 ralonsoh sfinucan: I'll take a look at https://review.openstack.org/#/c/451433/
16:17:31 sfinucan That'll do nicely. Ping you when it's ready for eyes :)
16:17:39 sfinucan ralonsoh: Don't bother. It's not even close to complete
16:17:42 ralonsoh sfinucan: ok!
16:17:45 sfinucan More of a hobby project, really
16:21:29 sfinucan jaypipes: Ahem https://docs.openstack.org/contributor-guide/writing-style/openstack-components.html https://review.openstack.org/#/c/475810/1/doc/source/scheduling.rst
16:21:44 sfinucan But I can go with 'Nova' if you _reallllly_ want it
16:22:14 jaypipes sfinucan: I stand corrected.
16:23:04 sfinucan jaypipes: Thoughts on that diagram tool in general? Seems like a lower barrier to entry than Inkscape etc., even if the output is less pretty?
16:23:21 jaypipes sfinucan: yup, I like it a lot.
16:23:27 sfinucan sweet
16:23:46 sfinucan with that, /me is off to tag (rugby)

17:13:48 melwitt mriedem: yes, those are ready for review. however I wanted to run it by jaypipes because, I'm interested in the "right way" to solve the BFV 0 disk problem in placement but I have no idea what to do or if it's possible right now
17:14:21 dtp mriedem want me to look those over?
17:19:58 mriedem dtp: i want everyone and their dog to look it over
17:25:12 dtp Bianca and Noodles are looking now

18:14:22 edleafe melwitt: You might want to take a look at https://review.openstack.org/#/c/473627/ - it includes the ability to zero-out standard resource class amounts in scheduler, while still having them present in the underlying flavor
18:14:58 melwitt edleafe: a-ha, cool. will look at that then. thanks
