15:55:48 bauzas lyarwood: unfortunately +Wd the live-mig job be non-votign
15:56:02 lyarwood ack thanks
16:06:35 gibi about the bug resolver bot I asked infra they said that https://meetings.opendev.org/irclogs/%23opendev/%23opendev.2021-08-03.log.html#t2021-08-03T16:31:32
16:11:16 melwitt thanks gibi
16:14:20 gibi so probably we lost the both the topic handling and the bug resolving capability of the bot during that transformatin
16:43:02 gibi If I had time I would be happy working on those bots
18:11:55 opendevreview Merged openstack/nova master: zuul: Mark live migration jobs as non-voting due to bug #1912310 https://review.opendev.org/c/openstack/nova/+/803585
21:12:41 nurdie Hey OS nova! I had to evacuate a failed compute node (it's super dead) on shared storage (ceph). 3 instances are hanging in "nova migration-list" as "accepted" but are already on another compute node. Does anyone know what galera db.table I can edit real quick to clear that up?
23:23:58 opendevreview melanie witt proposed openstack/placement master: Add consumer_types migration, database and object changes https://review.opendev.org/c/openstack/placement/+/669170

07:55:55 lyarwood gibi: Morning, https://bugs.launchpad.net/nova/+bug/1939108 but on the positive side, logsearch++
08:06:18 aarents bauzas: thanks for https://review.opendev.org/c/openstack/nova/+/764435 review, I applied the rephrasing.
08:13:22 gibi lyarwood: morning! could this be related to the guest blocking or delaying the detach attempt? I vaguly remember we discussed such option before
08:14:52 lyarwood gibi: yeah it's likely that, I need to push the tempest change ahead to rework detach so we actually dump the console to know either way
08:15:08 lyarwood iirc it was failing on something random the last time I rechecked
08:15:18 lyarwood https://review.opendev.org/c/openstack/tempest/+/794757
08:15:45 lyarwood yeah unrelated test_create_list_show_delete_interfaces_by_network_port ssh timeouts
08:15:48 lyarwood /o\
08:15:50 lyarwood rechecks again
08:16:17 lyarwood actually rebase as it has been that long
08:20:11 lyarwood gibi: https://github.com/gibizer/zuul-log-search-config/pull/1 btw, have a few ideas about the tool itself but I might not have time to hack on it until next week
08:29:56 gibi ohh, ok, lets hope the console log reveale something, other than that we can only increase timeout for the single detach attempt or increase the amount of retry we do
08:30:39 lyarwood indeed, 1 hit in the last 100 failures however suggests we are somewhere close to getting this right in CI finally
08:31:11 gibi lyarwood: if you have ideas about the feel free to note them in an github issue or directly in the TODO.md in the repo
08:31:53 lyarwood ack will do, it's mostly basic stuff like an argument for number of days back to search for etc and maybe a handler for logstash but that's it at the moment
08:31:56 gibi lyarwood: thanks for looking at that func faiure I had the intention to look at both func faiures but I had no time since and probablny not even today
08:40:49 bauzas aarents: thanks for the ping, just rechecked and +2d
08:43:53 aarents bauzas: thanks
09:08:16 opendevreview Pierre Libeau proposed openstack/nova master: Move file system freeze after end of mirroring https://review.opendev.org/c/openstack/nova/+/803713
09:08:59 opendevreview Lee Yarwood proposed openstack/nova master: func: Increase rpc_response_timeout in TestMultiCellMigrate tests https://review.opendev.org/c/openstack/nova/+/803714
09:09:52 lyarwood gibi / bauzas / stephenfin ; ^ okay I think that's a pretty trivial fix to the functional failures, I don't get why it's suddenly an issue but as this RPC call to the conductor then calls down to the source I'm assuming we've added some additional overhead somewhere and were not creeping over the 1 second timeout in the test.
09:10:10 lyarwood are now*
09:12:58 gibi lyarwood: will check soon
09:42:57 kashyap lyarwood: What's the "best" manual way to change the video model for an existing instance? (Asking for a friend.) Is the following painful approach the only way?
09:43:30 kashyap lyarwood: (1) Stop the instance. (2) snapshot it (what kind?). (3) Update the metadata on the snapshot image to use 'virtio' display dev. (4) Then rebuild the instance using the snapshot
09:43:34 kashyap Any better way than that?
09:43:54 kashyap (Besides the future goodness of 'nova-manage' command akin to machine_type update)
09:44:27 lyarwood if you want to persist the instance data then yeah I think that's the only way
09:44:42 lyarwood I don't think resize would change it
09:45:16 kashyap I see.
09:45:41 kashyap And for new instances, obviously start with: openstack image set --property hw_video_model=virtio [...]
09:46:54 lyarwood yeah
09:48:00 kashyap Or:
09:48:01 kashyap $ openstack server create --flavor m1.micro \
09:48:01 kashyap --image Fedora34 \
09:48:01 kashyap --property 'hw_video_model=virtio' vm1
09:48:05 kashyap Thanks!
09:52:10 lyarwood I don't think the second command is valid?
09:54:53 lyarwood oh it's metadata
09:55:07 lyarwood so yeah that isn't going to do anything kashyap
09:55:53 kashyap lyarwood: Oh, I see. So what's the way again to set the prop while creating the server?
09:56:35 lyarwood For new servers you would update the associated image
09:56:49 lyarwood for the existing server case you'd update the snapshot image
09:57:03 lyarwood and then in both create a new server from the image
09:57:36 opendevreview Merged openstack/nova master: compute: Avoid duplicate BDMs during reserve_block_device_name https://review.opendev.org/c/openstack/nova/+/801990
09:58:19 stephenfin kashyap: Echoing what lyarwood said, we don't expose this kind of knob via flavor extra specs. It's only possible via image metadata properties which rn require a rebuild to change
09:58:59 kashyap stephenfin: lyarwood: Thank you very much, both. I don't have this top off my head.
09:59:02 stephenfin kashyap: you can find a full list of all supported extra specs here https://docs.openstack.org/nova/latest/configuration/extra-specs.html
09:59:05 kashyap I'll correct my mistake on a bugzilla
10:01:51 opendevreview Lee Yarwood proposed openstack/nova stable/wallaby: Add functional test for bug 1937375 https://review.opendev.org/c/openstack/nova/+/803717
10:01:52 opendevreview Lee Yarwood proposed openstack/nova stable/wallaby: compute: Avoid duplicate BDMs during reserve_block_device_name https://review.opendev.org/c/openstack/nova/+/803718
10:02:04 pjakuszew kashyap: I wrote a script which modifes extra_specs on existing instances, though I consider it dangerous
10:02:38 kashyap pjakuszew: Heh, understood. The intersting question is - did it work reliably for you, without any nasty side-effects?
10:03:28 opendevreview Lee Yarwood proposed openstack/nova stable/victoria: Add functional test for bug 1937375 https://review.opendev.org/c/openstack/nova/+/803720
10:03:29 opendevreview Lee Yarwood proposed openstack/nova stable/victoria: compute: Avoid duplicate BDMs during reserve_block_device_name https://review.opendev.org/c/openstack/nova/+/803721
10:04:59 pjakuszew kashyap: In my case it was a case of adding a cpu_type key to a flavor, then syncing the flavor metadata to instance and reqspec extra_specs - in your case (hw_video_model=virtio) I guess you will have to do a hard reboot so the libvirt xmls will be regenerated
10:05:32 kashyap pjakuszew: Yep; in this case hard-reboot is unavoidable
10:06:44 pjakuszew let me check it, one sec
10:13:47 kashyap pjakuszew: Note, though: I don't have any environment to try this out. I'm just documenting some stuff due to a fallout downstream
10:13:53 kashyap But thank you! :)
10:15:22 pjakuszew kashyap: sure, I'm checking the differences between the xmls with and without properties right now
10:15:43 pjakuszew so I can check if the metadata change was properly propagated after hard reboot later

10:17:28 bauzas wow, I can see light at the end of the tunnel : https://events.linuxfoundation.org/kubecon-cloudnativecon-north-america/register/
10:21:47 kashyap pjakuszew: Thank you; do keep me posted. And post a link to your script - perhaps that can be added in some dangerous_utils/ directory
10:22:21 kashyap bauzas: That's still living in la-la-land for LF -- I doubt many will register until the dust settles with the Delta variant
10:22:59 bauzas kashyap: yup and the travel ban is still effective, but that's a fresh change at least for dometic flights
10:24:06 kashyap bauzas: Domestic flights in the US, you mean?
10:24:13 bauzas yup
10:24:33 bauzas this gives us some direction
10:24:48 pjakuszew kashyap: this is something I wanted to add into nova_manage in a more accessible form, actually

10:25:22 bauzas conferences could run for a mixed virtual+physical system until restrictions slowly improve
10:25:43 kashyap Mixed confs suck like hell :-( It frustrates both in-person and the remotees
10:26:10 kashyap "Can you hear me? Oh, I was talking to myself. Anybody there? Oh, you all went for a coffee break? Never mind"
10:34:02 pjakuszew kashyap: are these server properties visible in the libvirt xml in your case? looks like adding that property both under server create --property and manually on another one doesn't seem to propagate
10:34:26 kashyap pjakuszew: They are not; see stephenfin's comment earlier
10:34:51 pjakuszew oh I overlooked that
10:35:10 kashyap pjakuszew: Only way for existing instances are what lyarwood mentioned earlier (snapshot the image; adjust the property; and then boot an instance off the updated snapshot image)
