10:37:10 opendevreview sean mooney proposed openstack/nova master: [WIP] perf: add ironic startup perf simulator and analysis https://review.opendev.org/c/openstack/nova/+/980641
10:37:10 opendevreview sean mooney proposed openstack/nova master: [WIP] perf(ironic): eliminate O(N²) ProviderTree deepcopy at startup (B6) https://review.opendev.org/c/openstack/nova/+/980676
10:37:11 opendevreview sean mooney proposed openstack/nova master: [WIP] perf(ironic): suppress redundant _refresh_cache calls during startup (B1) https://review.opendev.org/c/openstack/nova/+/980677
10:37:11 opendevreview sean mooney proposed openstack/nova master: [WIP] perf(ironic): background _error_out_interrupted during startup (B4) https://review.opendev.org/c/openstack/nova/+/980678
10:37:12 opendevreview sean mooney proposed openstack/nova master: [WIP] perf(compute): parallelise per-node update_available_resource loop (B2) https://review.opendev.org/c/openstack/nova/+/980679
10:37:12 opendevreview sean mooney proposed openstack/nova master: [WIP] docs: update startup.md with post-optimisation measurements https://review.opendev.org/c/openstack/nova/+/980680
10:50:15 sean-k-mooney rmnijgh: it calls it because it was oen of the ways we heal the resouces asyncornsly, it runs every 5 mintues by defualt. it used to be used to move pci device form claimed to allocated. although on newer release i belive we do that seperatly
10:51:51 sean-k-mooney i dont think that call shoudl be needed in antelop+ possibly a little eailer but
10:52:04 sean-k-mooney we have not exaimed if it can be remvoed again
11:05:53 rmnijgh I can confirm this bug report #2085709, we have a large kolla-ansible openstack cluster. And nodes with 50+ instances take ages to migrate (or even timeout), but also the regular periodic task update_available_resource takes ages. Can the reviews in this report perhaps get review priority? I think I'm able to make changes in these two commits when neccesary.
12:33:29 opendevreview Lajos Katona proposed openstack/nova master: docs: Update libvirt version support matrix for 26.1 Gazpacho https://review.opendev.org/c/openstack/nova/+/980703
12:51:15 opendevreview Merged openstack/nova stable/2026.1: Update .gitreview for stable/2026.1 https://review.opendev.org/c/openstack/nova/+/980404
13:02:06 opendevreview Merged openstack/nova stable/2026.1: Update TOX_CONSTRAINTS_FILE for stable/2026.1 https://review.opendev.org/c/openstack/nova/+/980405
13:59:27 zigo Building Nova backport to Trixie leads me to these unit test failures:
13:59:27 zigo https://paste.opendev.org/show/bgO4WRXAvotrU1s66cx8/
13:59:27 zigo sean-k-mooney: Does some of them ring a bell?
14:04:51 zigo As much as I can see, I have 5 types of failures.
14:07:41 nicolairuckel elodilles: Thanks for restarting the pipeline. The same test failed a few times already though so I'm wondering if that's a bigger issue with the CI. And when it doesn't fail, another (unrelated) test fails.
14:14:21 elodilles nicolairuckel: i was having the same feeling - that something introduced a bug in tempest (?) - but then i saw a successful job run on stable/2025.2 branch, so it's either got fixed, or it's disappeared somehow o:) so i gave it another try now :)
14:19:19 zigo The aquire_lock thingy looks like probably comming from the fasterners version, I'm fixing that.
14:26:00 nicolairuckel Fingers are crossed that it works now. :D
14:27:00 elodilles nicolairuckel: grenade-skip-level passed already ( https://zuul.opendev.org/t/openstack/build/337549cbec7f480a8f36bba5cd23f208 ) now only the others should do the same. fingers crossed, indeed ;)
14:34:45 opendevreview Elod Illes proposed openstack/placement stable/2025.1: [CI][stable-only] Fix docs job https://review.opendev.org/c/openstack/placement/+/980761
14:52:18 opendevreview Elod Illes proposed openstack/osc-placement stable/2024.2: [CI][stable-only] Workaround for missing pkg_resources https://review.opendev.org/c/openstack/osc-placement/+/979691
14:56:44 zigo Ok, that fixed 10 unit tests, now only got the oslo.middleware api-paste.ini loading thingy to fix ... (plus one unit test that looks like non-deterministic).
15:05:28 zigo The healthcheck thing is probably due to my own patch.
15:11:48 zigo Yeah, all is passing now. :P
15:13:11 zigo Any reason why oslo.policy was taken away from nova.conf namespace list when generating it?
15:13:22 zigo Is this handled in nova.conf namespace?
15:19:29 Uggla Nova upstream meeting in ~40mn
15:32:52 worteks-thidem Hey, I try to propose a PR for rotatation rate in Libvirt, I know it is a old subject. But I have few applications use this informations to make a choice on specific scheduler. My PR is here : https://review.opendev.org/c/openstack/nova/+/979693. If somebody can review my code and explain me if I forget something.

15:56:06 s3rj1k Hi, I would like to ask for review of https://review.opendev.org/c/openstack/nova/+/973924, this is mainly needed for Metal3 support and complementary PR is already proposed to Cloud-Init, I am hoping that Nova can consider merging this so cloud-init feature gets unblocked for merge
