| 17:07:33 | noonedeadpunk | I've spotted there's also an scsi blueprint without spec: https://blueprints.launchpad.net/nova/+spec/libvirt-add-support-for-virtio-scsi-multiqueue | |
| 17:09:19 | noonedeadpunk | it seems that these 2 should not be conflicting with each other and I assume both can be implemented? | |
| 17:11:14 | noonedeadpunk | as if I'm not mistaken, that Windows virtio-blk driver is always a single queue, so the way to get any disk performance on windows would be to have scsi and multiqueue there | |
| 17:16:15 | noonedeadpunk | jsut trying to validate if I'm sane and can proceed to working on spec :) | |
| 17:16:27 | noonedeadpunk | (or it could be specless one) | |
| 17:17:39 | dansmith | noonedeadpunk: we have at least three things that are all related, so probably best to have a PTG discussion on it | |
| 17:18:02 | dansmith | domain iothreads, device iothread pinning, and any of these queue things are probably related enough to combine into a single conversation | |
| 17:18:05 | noonedeadpunk | also ports multique I guess? | |
| 17:18:16 | noonedeadpunk | yeah | |
| 17:18:20 | noonedeadpunk | fair enough | |
| 19:47:20 | opendevreview | melanie witt proposed openstack/nova master: DNM vtpm tempest https://review.opendev.org/c/openstack/nova/+/957477 | |
| 20:10:26 | sean-k-mooney | noonedeadpunk: https://review.opendev.org/c/openstack/nova-specs/+/953940 i sthe related one that we created to try and scope down the propsoal to make some progres in 2025.2 but that also got hit by spec freeze | |
| 20:11:31 | sean-k-mooney | noonedeadpunk: im hoping that Masahito will pick up the prosal again this cycle if they have time | |
| 20:12:59 | sean-k-mooney | this was the other thing they were interested in https://review.opendev.org/c/openstack/nova-specs/+/938823 | |
| 20:14:04 | sean-k-mooney | so there multiple iothreds, mapping disk queues to iothread and filterign service by netwrok id | |
| 20:14:14 | sean-k-mooney | i dont know which is there priority | |
| 20:15:56 | sean-k-mooney | noonedeadpunk: im just siging off for today but i assuem you want to progress the live migration concurncy feture as well in 2026.1 | |
| 20:16:12 | sean-k-mooney | i know there was some code up for that but i lost track for where that review was | |
| 20:16:44 | sean-k-mooney | noonedeadpunk: this was your spec for that https://review.opendev.org/c/openstack/nova-specs/+/955783 | |
| 20:17:01 | sean-k-mooney | but i also belive there was a specless blueprint approved indepently? | |
| 20:18:19 | sean-k-mooney | this was your bluepint https://blueprints.launchpad.net/nova/+spec/libvirt-parallel-migrate but https://blueprints.launchpad.net/nova/+spec/libvirt-migrate-parallel | |
| 20:18:29 | sean-k-mooney | was appoved then deferd | |
| 20:20:03 | sean-k-mooney | noonedeadpunk: so we currently have two competing propsoals for this one form you and another form Fabian Wiesel | |
| 20:22:58 | sean-k-mooney | noonedeadpunk: given they have revierd and +1 your versiohn i assume yours is the one that we inteded ot proceed with but we shoudl abandon one fo them and if decied if its goign to be specless or requrie a spec | |
| 20:24:41 | sean-k-mooney | Uggla: fyi ^ do you have any prefernce on which of the two blueprint we use and if we want to proceed specless or not | |
| 20:34:16 | melwitt | sean-k-mooney: do you happen to know if this needs to be changed to something else, perhaps devstack@q-ovn-metadata-agent ? now that q-agt is not used? https://github.com/openstack/nova/blob/master/roles/run-evacuate-hook/tasks/main.yaml#L24 | |
| 20:35:37 | melwitt | I'm working on vtpm tempest tests and noticed the error "controller | Unit devstack@q-agt.service could not be found." in the zuul stream | |

| #openstack-nova - 2025-10-03 | |||
| 07:02:57 | noonedeadpunk | sean-k-mooney: Uggla fwiw, I also have an implementation for parallel live migrations as well: https://review.opendev.org/c/openstack/nova/+/955784 | |
| 07:03:59 | noonedeadpunk | and yeah, I missed the specless one when was working on it :( | |
| 07:05:25 | bauzas | sounds to me a good PTG discussion anyway :) | |
| 07:05:51 | bauzas | it looks like we have a momentum, it would be sad to not having anything for Gazpacho :) | |
| 07:06:20 | noonedeadpunk | and regarding iothreads - I think I have yet another thing to add. or well. there is a specless blueprint already, and I have minimal implementation | |
| 07:06:34 | noonedeadpunk | yeah, totally sounds like a good topic for the PTG | |
| 07:06:44 | Uggla | noonedeadpunk That's a bit sad, to have competing proposal. Anyway yes I agree let's discuss that at PTG. | |
| 07:07:28 | noonedeadpunk | Uggla: they are *exactly* the same | |
| 07:07:36 | noonedeadpunk | so nothing sad I guess | |
| 07:08:54 | bauzas | oh yeah, that just means this should be a good and important effort for this cycle :) | |
| 07:08:57 | noonedeadpunk | I even come up with exactly same config name | |
| 07:09:11 | noonedeadpunk | without seeing yours | |
| 07:09:18 | Uggla | sad because we have to choose one and for one of you, it is a "waste" of time. | |
| 07:09:18 | bauzas | do you read minds ? don't reply, I'm afraid of the answer | |
| 07:09:59 | bauzas | were the competing blueprints both accepted ? | |
| 07:10:12 | noonedeadpunk | neither was so far | |
| 07:10:18 | noonedeadpunk | and one blueprint is specless | |
| 07:10:21 | noonedeadpunk | another has a spec | |
| 07:10:34 | bauzas | if not, that's understandable that two different people can start working on a same feature, while nothing is communicated | |
| 07:10:36 | noonedeadpunk | and given implementation is the same, I don;'t think much time was wasted | |
| 07:10:58 | noonedeadpunk | btw | |
| 07:11:12 | noonedeadpunk | author of https://blueprints.launchpad.net/nova/+spec/libvirt-migrate-parallel voted positively on my implementation :) | |
| 07:11:28 | bauzas | that's cool | |
| 07:11:29 | noonedeadpunk | So they are at least aware of this | |
| 07:14:11 | noonedeadpunk | but regarding iothreads, I think I have one more thing to add on top of https://review.opendev.org/c/openstack/nova-specs/+/938823 and https://review.opendev.org/c/openstack/nova-specs/+/951636 | |
| 07:15:25 | noonedeadpunk | or well. let's discuss on PTG :D | |
| 07:15:28 | bauzas | not sure I understand the relationship between io threads and network IDs, but that's probably related to some network IO concern. Anyway, let's wrap that for the PTG | |
| 07:16:12 | noonedeadpunk | if you get into umbrella of "improving guest performance and enable threading capabilities exposed by libvirt" - they are | |
| 07:16:16 | noonedeadpunk | but yeah | |
| 07:16:44 | noonedeadpunk | it can be all formulated as one point in cycle-highlights :) | |
| 07:17:00 | bauzas | glancing at https://review.opendev.org/c/openstack/nova-specs/+/938823/4/specs/2025.2/approved/network-id-query.rst, this was apparently a Nova API performance change, not something related to libvirt | |
| 07:17:18 | bauzas | but I can be wrong | |
| 07:17:35 | noonedeadpunk | oh, I get the wrong spec then | |
| 07:20:16 | Uggla | noonedeadpunk, add this point (// live migration) the ptg agenda ? If not already done. | |
| 07:20:51 | noonedeadpunk | do you have a specific etherpad for PTG already? | |
| 07:20:56 | Uggla | yes | |
| 07:21:15 | noonedeadpunk | oph, it's in channel; topic | |
| 07:21:26 | Uggla | not updated yet in the channel | |
| 07:21:46 | Uggla | https://etherpad.opendev.org/p/nova-2026.1-ptg | |
| 07:21:49 | noonedeadpunk | ok, and replacing 2025.2 with 2026.1 gives the new one | |
| 07:27:40 | noonedeadpunk | done, thanks! | |

| 09:40:40 | gibi | sean-k-mooney: bauzas: I moved https://review.opendev.org/c/openstack/placement/+/962775 to the front of the bugfix series as it can land already while I'm cleaning up the rest. So if you have time I appreciate a review there | |
| 09:42:05 | bauzas | gibi: I can try to look at it this afternoon | |
| 09:42:13 | bauzas | I don't have a lot of context but I'll try to find it :) | |
| 09:42:25 | gibi | that patch removes two debug logs that is it | |
| 09:42:26 | gibi | :) | |
| 09:42:41 | gibi | those debug logs generated gigabyte of logs | |
| 09:42:48 | gibi | in certain queries | |
| 09:43:04 | bauzas | ahah I see, then hopefully it should be simple to review :) | |
| 09:43:10 | gibi | it is :) | |
| 09:43:24 | gibi | the rest is a lot more complex and not ready for final review | |
| 09:45:06 | bauzas | yup, saw it | |
| 09:45:07 | bauzas | +2d | |
| 09:45:12 | gibi | thanks | |
| 09:45:17 | gibi | have a nice session in the gym | |
| 09:45:35 | Uggla | ping sean-k-mooney about https://launchpad.net/nova/2026.1 | |
| 09:45:43 | bauzas | well, it will be outside :) | |
| 09:45:57 | bauzas | more a cardio session than a gym | |
| 09:48:32 | sean-k-mooney[m] | Uggla: that looks correct as do the status of the other serise +1 | |

| 10:30:07 | sean-k-mooney | bauzas: the only releationship is the same person was proposing both specs | |
| 10:31:11 | sean-k-mooney | bauzas: masahito was interested in implente iothread, mapping io queue to iothread adnfilterign service by network in the last ptg | |
| 10:32:31 | sean-k-mooney | my io thread spec focuse just on the the simplest useful implemeation of iothread basicly spliting it out form the ioqueue work so it can be delivered independtly and incrementally | |
| 10:33:21 | sean-k-mooney | bauzas: im hoping masahito or noonedeadpunk or anyone else who is interested will have time to work on some of these prosposals this cycle | |
