| 16:09:46 | openstackgerrit | Stephen Finucane proposed openstack/nova master: libvirt: Add support for virtio-based input devices https://review.opendev.org/756552 | |
| 16:10:18 | bauzas | zigo: huh, that's horrible | |
| 16:10:53 | bauzas | I have to leave it now but I can take a look at why reno is f*** up tomorrow morning | |
| 16:11:38 | bauzas | my best guess is that since we branched, the current points to wallaby but we forgot to deliver a victoria page | |
| 16:11:47 | bauzas | this should be easy to fix | |
| 16:11:56 | bauzas | zigo: ^ | |
| 16:14:02 | bauzas | mmmm, we have merged the necessary tho https://review.opendev.org/#/c/754321/ | |
| 16:14:04 | bauzas | gibi: gmann: ^ | |
| 16:14:35 | bauzas | lemme try to reproduce it locally | |
| 16:15:46 | gmann | it merged on 5th so reno site should be updated. | |
| 16:16:49 | gmann | in patch generated reno it was fine https://abad4d81dfb03b4f334d-70b013fe9ea05f673313d916271f541a.ssl.cf5.rackcdn.com/754321/1/check/build-openstack-releasenotes/b3856fd/docs/ | |
| 16:17:58 | bauzas | yup | |
| 16:18:17 | bauzas | I'm still waiting for my local run to end up but I don't see any problems | |
| 16:18:42 | bauzas | I guess that that's the mirrors which still get stale data | |
| 16:21:17 | gmann | yeah, i think mirroring is the issue. I will check in after some time (in my evening) in case. | |
| 16:21:54 | bauzas | gmann: I don't know who to ping for such cases, this is not managed by infra folks AFAIK | |
| 16:22:36 | bauzas | gmann: but use wisely your TZ card, you should get more people interested in this issue than with my own TZ ;) | |
| 16:22:43 | bauzas | anyway, needs to drop | |
| 16:22:55 | bauzas | will populate the local run result when I'm back | |
| 16:23:04 | gmann | bauzas: sure, i will check with clark | |
| 16:23:54 | elod | bauzas gmann zigo : if i'm not mistaken there's another investigation around the issue, see: https://review.opendev.org/#/c/756553/1 | |
| 16:24:58 | gmann | elod: ah, yeah it is issue in publishing only so we can wait for this fix to merge | |
| 16:35:01 | bauzas | gmann: elod: I do confirm everything is OK on my local build | |
| 16:35:08 | bauzas | definitely a publishing issue | |
| 16:35:28 | bauzas | zigo: in the meantime, just build the notes locally (tox -ereleasenotes) | |
| 16:35:43 | bauzas | anyway, bailing out | |
| 17:06:58 | openstackgerrit | Merged openstack/nova-specs master: Make 'Feature Liaison' optional in test https://review.opendev.org/748591 | |
| 20:08:49 | gmann | bauzas: elod zigo wait for the next rc tag (which is this week) for release note page fix. reno publish job last ran is on same day victoria branch is cut (https://review.opendev.org/#/c/754319/) so it did not include the changes for victoria. - https://zuul.opendev.org/t/openstack/builds?job_name=publish-openstack-releasenotes-python3&project=openstack%2Fnova | |
| 20:11:23 | zigo | gmann: Thanks ! | |
| 20:12:13 | zigo | In fact, I was looking for info about why Nova needs Qemu >= 4 (I was surprised when I started my first compute with Victoria this morning). | |
| 20:12:39 | zigo | And I was wondering if I also need a newer libvirt than 5.0. | |
| 20:19:29 | gmann | zigo: ohk, this is reno for qemu version bump https://review.opendev.org/#/c/746981/9/releasenotes/notes/victoria-libvirt-version-bump-e1a09b3a72ee56a4.yaml | |
| 20:20:25 | zigo | Oh, good, so I wont have to also backport libvirt for Buster ! :) | |
| 20:20:29 | zigo | Perfect. | |
| 20:20:38 | zigo | There's already qemu 5.0 in buster-backports. | |
| 20:21:02 | zigo | The annoying bit, is that it also pulls the Linux kernel from backports, but that's ok-ish I guess. | |
| 20:21:18 | zigo | Just annoying when upgrading the cluster (ie: needs reboot). | |
| 20:22:41 | zigo | I would have very much prefered if Qemu 3.1 could still be in use in Victoria for a last time ... | |
| 20:22:53 | zigo | nv mind... | |
| 20:23:30 | zigo | Can anyone tell me what new feature was needed? | |
| 20:49:02 | gouthamr | o/ hello gibi, nova contributors - i work on manila, and a few of us wanted to discuss virtiofs with you at the upcoming PTG, i've added the topic to https://etherpad.opendev.org/p/nova-wallaby-ptg and will keep it updated with any more material we generate | |
| 20:52:06 | gouthamr | i'm hoping we can avoid an overlap in schedules if this discussion could be accommodated on thursday/oct 29th :) | |
| 20:54:26 | artom | zigo, you mean what caused the 3.1 min qemu version bump? | |
| 20:54:39 | zigo | Yeah. | |
| 20:57:06 | artom | zigo, nothing specific, it looks like: https://review.opendev.org/#/c/695056/ | |
| 20:57:25 | artom | There are mailing list discussions linked in that commit message around min versions | |
| 20:59:44 | zigo | artom: This doesn't feel right to me, there's no actual reason specified for the bump ... :/ | |
| 21:00:18 | artom | zigo, I don't necessarily disagree (though I don't know enough context to have an informed opinion) | |
| 21:00:25 | artom | But... it is what it is :/ | |
| 21:04:23 | zigo | Well, I regret I didn't take part of the discussion, but "oh, it's been a long time we didn't bump ..." is for sure *not* a good reason. | |
| 21:07:44 | artom | zigo, surely there was other stuff as well | |
| 21:07:55 | artom | It removes old code, etc... | |
| 21:08:05 | artom | zigo, anyways, I'm just the messenger :P | |
| 21:08:16 | zigo | :) | |

| 05:48:14 | openstackgerrit | melanie witt proposed openstack/nova master: Follow up for cherry-pick check for merge patch https://review.opendev.org/756639 | |
| 07:14:11 | gibi | dansmith: I'm OK to connect https://review.opendev.org/756534 to the old bp, just add reno for visibility | |
| 07:24:09 | gibi | gouthamr: hi! | |
| 07:25:22 | gibi | gouthamr: thanks for ping | |
| 07:26:26 | gibi | gouthamr: would the manial team needs a dedicated 1 hour slot to discuss this or is it OK If I schedule it to Thursday 13:00-17:00 UTC dynamicall? Is there a preferred time slot during that day for the manial folks? | |
| 08:22:47 | stephenfin | zigo: We bump the minimum version of libvirt regularly to help reduce the conditional soup that is the libvirt driver | |
| 08:23:18 | bauzas | good morning Nova | |
| 08:24:38 | gibi | bauzas: good morning | |
| 08:30:23 | kashyap | stephenfin: I thought the "conditional soup" has reduced quite a bit lately ... a couple of years ago, though. It's all MIN_VERSION_THIS, MIN_VERSION_THAT ;-) | |
| 08:53:35 | openstackgerrit | Jorhson Deng proposed openstack/nova master: optimize the shelve code flow https://review.opendev.org/756665 | |
| 08:57:10 | zigo | stephenfin: Thanks, makes sense. | |
| 09:11:50 | openstackgerrit | Stephen Finucane proposed openstack/nova master: libvirt: Only add a USB controller if it's necessary https://review.opendev.org/756549 | |
| 09:11:50 | openstackgerrit | Stephen Finucane proposed openstack/nova master: libvirt: Remove support for '[libvirt] use_usb_tablet' https://review.opendev.org/756550 | |
| 09:11:50 | openstackgerrit | Stephen Finucane proposed openstack/nova master: libvirt: Rationalize attachment of USB tablet https://review.opendev.org/756551 | |
| 09:11:51 | openstackgerrit | Stephen Finucane proposed openstack/nova master: libvirt: Add support for virtio-based input devices https://review.opendev.org/756552 | |
| 09:12:45 | stephenfin | gibi: See, it's not just me :-P https://review.opendev.org/#/q/topic:mypy+(status:open+OR+status:merged) | |
| 09:13:39 | gibi | stephenfin: it spreading... :) | |
| 09:15:05 | gibi | anyhow I have no hard problem with mypy I'm still lack the hands on experience to feel confortable. | |
| 09:18:17 | stephenfin | I think that still applies to everyone (I started work on an o.vo extension and quickly gave up). Still, baby steps. I'm interested in seeing how Cinder solve the o.vo problem, if indeed they do | |
| 09:21:10 | gibi | ovo is an interesting challenge. if I would have free time... :) | |
| 09:41:30 | whoami-rajat__ | hi kashyap | |
| 09:41:37 | kashyap | Hi | |
| 09:42:11 | whoami-rajat__ | i had some queries regarding the patch i'm working on https://review.opendev.org/#/c/756261/ | |
| 09:42:24 | kashyap | Go for it | |
| 09:42:56 | whoami-rajat__ | the usecase is simple, we create a dependency chain vol1 -> snap1 -> snap2 and we try to delete snap2 from cinder when the VM is off | |
| 09:43:38 | whoami-rajat__ | incase of online blockCommit, nova/libvirt updates the backing_file of snap2 from snap1->vol1 but incase of qemu-img commit | |
| 09:43:40 | kashyap | (Side note: you'd want to use the arrow the other way around to represent the backing files :-) vol1 <- snap1 <- snap2) | |
| 09:43:56 | whoami-rajat__ | oh yep | |
| 09:44:05 | whoami-rajat__ | active file is the last one | |
| 09:44:13 | kashyap | Yes | |
| 09:44:15 | whoami-rajat__ | vol1 <- snap1 <- snap2 | |
| 09:44:30 | whoami-rajat__ | anyway, when i try to do it offline using qemu-img commit | |
| 09:44:50 | whoami-rajat__ | the file gets commited snap1 to vol1 but i'm not sure how to update the backing_file of snap2 | |
| 09:46:29 | whoami-rajat__ | just for ease of referencing, these are the places where nova does online blockCommit | |
| 09:46:30 | whoami-rajat__ | https://github.com/openstack/nova/blob/master/nova/virt/libvirt/driver.py#L3130-L3131 | |
| 09:46:36 | whoami-rajat__ | https://github.com/openstack/nova/blob/master/nova/virt/libvirt/guest.py#L822-L832 | |
| 09:46:47 | kashyap | whoami-rajat__: Offline: you can commit snap2 into snap1, and then snap1 back into vol1. What doesn't work for you? | |
| 09:47:00 | kashyap | Do you have a working example to show your problem? | |
| 09:48:10 | whoami-rajat__ | I'm not sure what you mean by working example, we issue ``cinder snapshot-delete snap1`` command from cinder that doesn't work right now | |
| 09:48:45 | whoami-rajat__ | the info send from cinder to nova is the current snap to be deleted and it's backing file only | |
| 09:49:52 | kashyap | whoami-rajat__: Okay, your question is: when doing it offline, once snap1 is committed to vol1, then how do you update the backing file reference of 'snap2' to 'vol1' -- correct? | |
| 09:50:08 | whoami-rajat__ | yep | |
