lyarwooderm that isn't supported at all10:12
lyarwoodyour placement allocations are going to be totally borked10:13
lyarwoodcan you undo the hostname change, empty the host of any instances and then do the hostname change?10:13

*** efried has quit IRC12:01
brinzhang_nightmare_unreal: of course ^^12:02
brinzhang_nightmare_unreal: IMO, this patch is ready a looong time, but I dont know the where need to change, and why no-body +2 or -1 for it12:04
sean-k-mooneybrinzhang_: it looks like it has not really got any code review12:05
sean-k-mooneyat least not in the last year or so12:05
sean-k-mooneynightmare_unreal: brinzhang_ so ye need to join the sdk/osc irc channel and talk to the core team about it12:06
nightmare_unrealcan we please have a review for that patch12:06
brinzhang_IMHO, since mriedem left, there is no body care that pach12:06
nightmare_unrealbrinzhang_:  i am in #osc  channel but couldn't find your username12:07
nightmare_unreali mean sdk12:07
sean-k-mooneythis is not the correct channel to ask in really. i think stephenfin might have osc core rights12:07
nightmare_unrealyeah right, sorry about the noise12:07
nightmare_unrealwe will move the disucssion12:07
sean-k-mooneyits ok to bring it up12:07
sean-k-mooneyits for nova migrations12:07
sean-k-mooneybut just bring it up here wont help get it merged12:08
nightmare_unrealhaha true12:08
sean-k-mooneyit might make sense to add a ptg topic12:08
sean-k-mooneyor a mailing list topic12:08
brinzhang_nightmare_unreal: yes, it also belongs to nova ^^12:08
sean-k-mooneyit might make sense to add teh core teams to osc12:08
sean-k-mooneyi.e. so each project core team that does not ahve a plugin can review there onw part of osc12:09
nightmare_unrealI see12:09
brinzhang_sean-k-mooney: ok, I will add the osc core to that patch12:09

sean-k-mooneygenerally you are better off to ask for reviews in irc12:15

stephenfinelod: So the former. I could, but it would involve even more significant rewriting of the tests I'm bringing back plus significant rewrite of any future tests that depend on this feature15:01
lyarwoodstephenfin: ^ as requested15:01
stephenfinlyarwood: thanks15:01
stephenfinelod: Given they're test-only (low risk) and avoid merge conflicts for this series and potentially many more tests in the future, I'm personally inclined to think they belong here.15:02
elodstephenfin: the test-only part is good, but still it would mean larger and larger extra refactor (due to conflicts) in older branches which could cause more problems later on maybe15:06
stephenfinelod: Fair point but tbh I'm not sure how much further back we should go. Those tests and the changes themselves are invasive enough that I think they may have to be rewritten if I want to go significantly further back15:08
stephenfinelod: In fact, I don't think we need to go further back. The main issue here was introduced by https://review.opendev.org/#/c/641806/ which was never backported15:10
stephenfinand was merged in train15:10
elodstephenfin: yes, that is another question, how far should a backport go. in general, whether a bugfix worth the backporting effort if it involves so much refactor, hence risks15:11
elodstephenfin: but i understand you are saying this won't go further than train15:12
stephenfingiven the nasty side-effects of this race (worst case scenario: doubly pinned instances) I think bringing it back to train makes sense15:13

sean-k-mooneyya i guess that could be it ill take a look15:46
sean-k-mooneyi made fucn be octal15:47
sean-k-mooney func = 0o015:47
sean-k-mooneybut ya it could be the formating15:47
stephenfin>>> x = 0o115:48
stephenfin>>> '%s' % x15:48
stephenfin'1'15:48
sean-k-mooneyok ya so that is proably it15:48
*** Yumeng has quit IRC15:48
sean-k-mooneycool now i need to look up hex/octal format codes :)15:49
sean-k-mooneyso it shoudl be o not s15:50
sean-k-mooneyor i guess x would work too for hex15:50

gibithe nova weekly meeting starts in 8 minutes in #openstack-meetings-315:52
gibiI mean #openstack-meeting-315:52
sean-k-mooneystephenfin: actully the adress is  0000:00:03. its missing the function e.g.  0000:00:03.1 vs  0000:00:03.15:59
sean-k-mooneyso its proably not the formating but its likely related to that change in my patch16:00

stephenfinsean-k-mooney, bauzas: Either of you know why we pass 'live=True' here instead of actually checking the power state of the instance as we do elsewhere? https://github.com/openstack/nova/blob/master/nova/virt/libvirt/driver.py#L439616:24
stephenfinfor both PCI (link above) and MDEV-type devices https://github.com/openstack/nova/blob/master/nova/virt/libvirt/driver.py#L751216:24
bauzaslooking16:25
stephenfinIs it because we pass 'persistent=True' when attaching them, e.g. https://github.com/openstack/nova/blob/master/nova/virt/libvirt/driver.py#L4425 ?16:25
sean-k-mooney i would expect use to be consistent16:27
*** mkrai_ has quit IRC16:27
sean-k-mooneygit blame on github does not work on that file because its too big16:27
sean-k-mooneywe want to remove it form both the live and persistt doamin that said we dont use the persitent domain16:27
bauzasstephenfin: "–live indicates that the operation is dynamic and will reflect in the running guest."16:28
*** jraju__ has quit IRC16:28
sean-k-mooneybauzas: right but that should be true of attach too16:28
stephenfinSo if the guest was paused or stopped, that would fail right?16:28
sean-k-mooneyhttps://github.com/openstack/nova/blob/f47bde539c89d1ac1fa90ea6f0d72a7e2de19532/nova/virt/libvirt/guest.py#L48816:28
sean-k-mooneyyes16:28
stephenfinso...bug?16:29
sean-k-mooneyalthough you cant detach from a paused guest16:29
sean-k-mooneyit will fail16:29
stephenfinPCI devices or anything?16:29
sean-k-mooneyso detach will send a acpi interupt to the guest16:29
stephenfinI guess PCI devices are different because of the whole "managed" aspect16:29
sean-k-mooneybut when its paused nothing will repond to that16:29
sean-k-mooneyso the detach shoudl fail16:30
sean-k-mooneythe same shoudl be true fo mdevs16:30
sean-k-mooneyin the pasued state the vm domain is still defined but the cpus are stopped16:30
sean-k-mooneyqemu is still running16:30
sean-k-mooneyunlike suspend16:30
stephenfindoes that also apply for e.g. block devices?16:31
sean-k-mooneyyes16:31
bauzasyou lost me, folks16:31
sean-k-mooneywe use virtio-blk which uses a  pci per volume by default16:31
sean-k-mooneyso volume detaches do a pci hot unplug16:31
sean-k-mooneyso it wont work on a paused guest16:31
sean-k-mooneyim not sure about virtio-scisi but i suspect that wont work either16:32
stephenfinbauzas: we're questioning whether the live parameter makes sense here https://github.com/openstack/nova/blob/master/nova/virt/libvirt/driver.py#L224716:32
stephenfinor if we should be outright rejecting a request to attach/detach a device from a paused guest16:32
sean-k-mooneystephenfin: i think we shoudl be passing both live and persisted in almsot every case16:32
sean-k-mooneystephenfin: i dont know of any reason we would not want to update both16:33
sean-k-mooneyalways16:33
sean-k-mooneywell i guess if the vm was off16:33
sean-k-mooneybut in htat case we dont need to update the domain16:34
sean-k-mooneywe will just recreated it when we start it16:34
stephenfinokay, let me see if I can untangle this /o\16:36
*** sapd__x has quit IRC16:38
sean-k-mooneythis could explain why we are getting out of sync16:43
sean-k-mooneythere is at least one bug where the live and perstient domains get out of sync16:44
sean-k-mooneyif we are attaching with persistent and detaching with live that would do it16:44
