22:16:47 openstackgerrit Merged openstack/nova stable/queens: Migrate tempest-dsvm-multinode-live-migration job in-tree https://review.openstack.org/567612
22:16:52 openstackgerrit Merged openstack/nova stable/ocata: Migrate tempest-dsvm-multinode-live-migration job in-tree https://review.openstack.org/567619
22:21:49 openstackgerrit Merged openstack/nova stable/pike: log stale allocations as WARNING instead of DEBUG https://review.openstack.org/567271
22:25:46 openstackgerrit Hongbin Lu proposed openstack/nova-specs master: Choose default network on ambiguity https://review.openstack.org/520247
22:28:05 melwitt mriedem: that would have been my first question too, whether they're using devstack or a real deployment. what's probably wrong is they need to pass the cell nova.conf to the console proxy service instead of the old global nova.conf
22:29:42 melwitt I'm thinking maybe I need to make the release note better to call that out
22:31:11 mrf Hi
22:31:27 mrf does images_rbd_pool at nova.conf support multiple pools?
22:31:31 openstackgerrit Merged openstack/nova master: Make get_instance_objects_sorted() be smart about cells https://review.openstack.org/509003
22:33:04 melwitt mrf: I don't believe so. mnaser could you confirm? ^
22:33:15 openstackgerrit Matt Riedemann proposed openstack/nova master: Add nova-slow job https://review.openstack.org/567697
22:33:30 mriedem there's your slow job
22:33:32 mnaser mriedem: it does not unfortunately, it can only use a single rbd image backend
22:33:36 mnaser err
22:33:39 mnaser mrf: ** ^
22:33:52 melwitt mriedem: awesome thanks
22:33:59 melwitt wznoinsk: ^
22:36:35 mriedem ok stable backports for this https://review.openstack.org/#/q/Ib10081150e125961cba19cfa821bddfac4614408 are ready
22:36:38 mriedem but probably no one around
22:39:59 mriedem oh tonyb mtreinish ^ :)
22:42:52 mrf mmm i got a trouble with 2 computes nodes , maybe some could help each one got diferent images_rbd_pool
22:43:04 mrf and now i cant migrate instances beetween them
22:45:13 tonyb mriedem: Thanks, I'll review them after this meeting
23:02:45 openstackgerrit Takashi NATSUME proposed openstack/nova master: Fix 500 error while passing 4-byte unicode data https://review.openstack.org/407514
23:03:04 openstackgerrit Takashi NATSUME proposed openstack/nova master: Adds view builders for keypairs controller https://review.openstack.org/347289
23:06:11 openstackgerrit melanie witt proposed openstack/nova master: Avoid warning log when image not exist https://review.openstack.org/567522
23:17:25 mriedem AHA!
23:17:50 melwitt what
23:18:15 mriedem https://github.com/openstack/nova/blob/master/nova/scheduler/filters/availability_zone_filter.py#L43
23:18:18 mrf O_O
23:18:19 mriedem we don't have a regression
23:18:36 mriedem if you didn't request an az on server create, the az filter doesn't take the current instance az into account
23:18:37 melwitt well I'll be
23:19:13 mriedem and clutchbeyers already left
23:19:16 melwitt disaster averted
23:25:50 mriedem we still have the up-call and data migration to deal with :)
23:26:03 mriedem we still have a regression since pike, just an easier one to deal with
23:26:34 mriedem will push up this functional test since i bothered writing it, and then i'm off
23:29:40 melwitt :( wah wah
23:29:45 melwitt thanks mriedem
23:30:07 openstackgerrit Matt Riedemann proposed openstack/nova master: Add implicit instance AZ + live migration test https://review.openstack.org/567701
23:30:13 mrf mmm i got a trouble with 2 computes nodes , maybe some could help each one got diferent images_rbd_pool, looking virshdump it point to rbd pool, can it be manually change the xmlfile to the new pool and them move the object at ceph level?
23:32:02 melwitt mrf: maybe. you could try asking an advance ceph operator like mnaser or ask on the openstack-operators mailing list where people can respond
23:33:59 mrf thank so much
23:34:14 melwitt good luck
23:37:07 openstackgerrit Tsuyoshi Nagata proposed openstack/nova master: nova improvement of maximum attach volumes more than 26 vols https://review.openstack.org/567472
23:43:44 mrf Why instance migration with blockmigration is not supported in a stopped vm? Cannot 'os-migrateLive' instance af02564c-8579-4226-96b7-99e3b650c06b while it is in vm_state stopped (HTTP 409) (Request-ID: req-aee842d9-593b-43fc-9487-e5eb191bc732)
23:48:06 melwitt mrf: just a guess, but I think the instance has to be running in order to do a live migration. that is, libvirt must need the instance running in order to do it
23:49:07 mrf yes but if i want only migrate storage of instance
23:49:16 mrf state can me started or stopped
23:49:30 mrf similar to other hypervisors like xenserver, hyperv, vmware
23:49:43 mrf you can do a storage migration without know if machine is live or stopped
23:50:29 mrf block-migration must not depend of machine state
23:51:54 melwitt maybe you want regular cold migration then? https://developer.openstack.org/api-ref/compute/#migrate-server-migrate-action
23:54:49 mrf --live must be specified if --block-migration or --disk-overcommit is specified
23:54:49 mrf it drops : [root@controller ~(keystone_admin)]# openstack server migrate --block-migration af02564c-8579-4226-96b7-99e3b650c06b
23:56:13 melwitt I think you don't need to pass --block-migration for a cold migrate
#openstack-nova - 2018-05-11
00:01:30 mrf but it fails because destination host does not have the same rbd_images_pool
00:01:47 mrf i think so
00:01:58 melwitt oh, so this is the same problem you were asking about earlier
00:04:16 melwitt live migration being rejected in a stopped vm is related to how live migration maps to the underlying libvirt function, so you'd have to ask someone who knows more about libvirt as to why that's not allowed. I'd ask kashyap about it but he's EU time zone and not around right now
00:05:19 mrf thanks :)
00:06:51 melwitt even if it didn't reject your request, I think you'd run into the same problem if the destination host is a different pool than the source
00:08:29 mrf yes but.. allowing a block storage migration from host A to B
00:08:48 mrf will allow that because it should choose the storage pool of the destination host
00:09:09 mrf i go a headache with two computes running instances in diferent pools
00:09:30 mrf and export / import is not the solution :)
00:10:22 gmann wznoinsk: melwitt mriedem: RE on slow test job. yes it used to be in tempest-full but they were excluded from this job due to timing and race issues.
00:10:46 melwitt mrf: did you try live migration with --block-migration while it's running to see what happens?
00:11:01 gmann this job legacy-tempest-dsvm-neutron-scenario-multinode-lvm-multibackend runs all scenario tests including slow + migration tests.
00:11:44 gmann we can move this to check pipeline from experimental like tempest does. but it is nv in tempest which we should make it voting
00:12:22 gmann cinder also have this in experimental job and there also it can be moved to check pipeline.
00:13:08 mrf melwitt: yes instance dont migrate from host
00:14:15 melwitt is it a different error than the cold migrate?
00:14:19 gmann in parallel we are trying to run all tests including slow in tempest-full-parallel job which is experiment and if no timing issue then we can bring back the slow tests in tempest-full job only
00:23:17 mrf Any ideas ? http://paste.openstack.org/show/720799/

06:12:31 gmann i replied. can you check if it make sense.
