| 16:54:46 | sean-k-mooney | i woudl prefer to always have memfd shared=true | |
| 16:55:13 | sean-k-mooney | but keep "annoumus" spelled correctly for those that want to opt out | |
| 16:55:27 | sean-k-mooney | i.e. evnetually memfd i think shoudl become the default | |
| 16:55:38 | sean-k-mooney | but ya in newer qemu memfd does not need numa | |
| 16:55:44 | sean-k-mooney | but it did when it was first done | |
| 16:57:24 | sean-k-mooney | the fact that memfd does not require numa affinity is one of the reaosn its intersting | |
| 17:01:25 | tkajinam | but not requiring numa is valid only when you don't need numa aware things, right ? | |
| 17:01:41 | tkajinam | I'm a bit confused because the spec mentions OVS-DPDK which likely require numa-aware allocation of cpu/mem | |
| 17:01:52 | tkajinam | while it might not be needed for virtio-fs thing | |
| 17:02:03 | sean-k-mooney | correct | |
| 17:02:18 | sean-k-mooney | memfd and numa affinity are ortoganal | |
| 17:02:26 | sean-k-mooney | if you want both you shoudl request both | |
| 17:02:59 | tkajinam | ok. that makes sense | |
| 17:03:52 | sean-k-mooney | today to use numa in nova you have to set hw:mem_page_size to any vallid value or use file backed memory | |
| 17:04:08 | sean-k-mooney | so memfd would not change that | |
| 17:05:18 | tkajinam | ok | |
| 17:14:36 | Uggla | dansmith, gouthamr, bauzas What I meant is during the PTG topic: | |
| 17:14:36 | Uggla | 1- We blocked actions on instances with an attached share to reduce the scope. | |
| 17:14:36 | Uggla | 2- Also mainly because older virtiofsd (<1.11) doesn’t support migration — per libvirt docs: “Older versions of virtiofsd (prior to 1.11) do not support migration…”, so ops like live-migration, save/restore, or memory snapshots may not work with a virtiofs share attached. (https://libvirt.org/kbase/virtiofs.html) | |
| 17:26:26 | Uggla | 3- So the blocked operation due to libvirt/qemu is not only live-migation but also suspend and shelve (I was unsure about the impacted ones during the call) | |
| 17:29:31 | dansmith | suspend I understand, but not shelve.. how does that have any requirement on libvirt/qemu? | |
| 17:33:48 | sean-k-mooney | i think we dont supprot snapshot and that the issue with shelve but we do allow nova to stop the vm to do snapshot | |
| 17:34:14 | sean-k-mooney | and for shelve specificly | |
| 17:34:23 | sean-k-mooney | we only do the snapshot in the shelve offload pahse | |
| 17:34:40 | sean-k-mooney | so the vm is stopped so ya i dont knwo why we could not od that today | |
| 17:35:20 | dansmith | I thought shelve did the snapshot not offload, but either way, the instance should be stopped already so yeah I can't think of why that would be a problem | |
| 17:43:31 | sean-k-mooney | offload might just bee the delete but i think the code path also diverges based on BFV vs image_type=rbd vs images_type=qcow | |

| 09:03:03 | stephenfin | gibi: sean-k-mooney: Morning 👋 Before the PTG kicks off, could I get some eyes on https://review.opendev.org/c/openstack/nova/+/985506? It's trivial but needed to unblock an u-c bump for o.vo | |
| 09:22:53 | gibi | stephenfin: done | |
| 09:23:08 | stephenfin | gibi++ ty 🙏 | |
| 11:15:13 | DominikDanelski[m] | I missed signing-up for the virtual PTG for 2026.2. Doest that mean that adding https://review.opendev.org/q/topic:%22bp/numa-topology-with-rps%22 (NUMA Topology with Resource Providers) is dead in the water? Are specs / code changes reviewed, if they haven't been added to the agenda? | |
| 11:20:26 | sean-k-mooney | DominikDanelski[m]: no, the ptg is for gaining concencous not for approving any specific feaute | |
| 11:20:47 | sean-k-mooney | so 1 it cna still happen via the normal spec review process and 2 if there is time it can still be included in the ptg adgenda | |
| 11:22:44 | sean-k-mooney | the main issue i have with the current code is the reqrite of numa_fit_instance_to_host | |
| 11:23:18 | sean-k-mooney | it not clear to me that you fully undersstood what that fucniton was ment to do in the context of numa in placment | |
| 11:25:11 | sean-k-mooney | in the numa filtier its role is to determin if a given allcoation candiate can fullifle the the numa request so we can filter the canidate in the host state object | |
| 11:26:04 | sean-k-mooney | in the compute manger/resocue tracker claim its role i sgieve a singel allcoation candate generate the full instnac enuma toplogy and confirm its still valid | |
| 11:27:03 | sean-k-mooney | that code was intentially written in a functional style so that it was a pure input of the parmater with no sideffect which is why the object oriatneted rewrite makes it harder to revew as it break the mental model we had for that code | |
| 11:27:48 | sean-k-mooney | even if the code is effectivly equvlent https://review.opendev.org/c/openstack/nova/+/971176/9/nova/virt/hardware.py is an invaisve rewrite | |
| 11:35:28 | opendevreview | Anton Iacobaeus proposed openstack/nova-specs master: Intel TDX support in libvirt driver https://review.opendev.org/c/openstack/nova-specs/+/979608 | |
| 11:38:30 | DominikDanelski[m] | sean-k-mooney: Did you see my reply in https://review.opendev.org/c/openstack/nova/+/971176/1/nova/virt/hardware.py#b2509? I think the change to the overall logic is not as significant as it may look from the lines of diff, but I asked about your input there and I'm open to changes if you provide direction for them. | |
| 11:47:04 | sean-k-mooney | i did but again because it fundemtnally change the organstaion of the code i have not had tiem to fully unlopad all my expecations fo how that code shoudl work adn rereview it based on yoru changes | |
| 11:47:19 | sean-k-mooney | as i said that refactoring makes it a lot harder to review your change | |
| 11:50:42 | sean-k-mooney | if you wanted to make that easier to review you would do the refactor in its own patch that does not change any exisitng behivor. although im not entirly conveice that is the correct move. it would make it much clear what is jsut a refactorign vs behvior change | |
| 12:13:50 | opendevreview | Esra Ozkan proposed openstack/nova master: Check volume status before live migration https://review.opendev.org/c/openstack/nova/+/973750 | |

| 12:24:08 | sean-k-mooney | Uggla: so its a little disapointing that the lack fo openstack client and sdk? supprot for nova share attatchment was not coverd in teh manilla cross project session | |
| 12:24:25 | sean-k-mooney | Uggla: i dont think we shoudl apcpate any new feature there really until that gap is closed | |
| 12:24:59 | sean-k-mooney | i dont object to any of the feature but without afctully coing that gap so you dont have to use curl im not sure we should keep exteneding it | |
| 12:25:18 | sean-k-mooney | oh... | |
| 12:25:22 | sean-k-mooney | sorry i msiste it | |
| 12:25:32 | Uggla | sean-k-mooney, good news the sdk and client were merged, it was the first topic of yesterday meeting. | |
| 12:25:47 | sean-k-mooney | ya i ddint see that initally | |
| 12:25:50 | sean-k-mooney | all good then | |
| 12:26:21 | Uggla | sean-k-mooney, gouthamr take over this and manage to cross the finish line. | |
| 12:27:15 | Uggla | sean-k-mooney no worries. | |
| 12:29:21 | Uggla | sean-k-mooney, also carloss presented good progress on the testing side. | |
| 12:30:42 | sean-k-mooney | shoudl i ask if said testing found bugs or not | |
| 12:33:16 | Uggla | sean-k-mooney, I would say yes at least one I'm aware of it --> 984802: Set instance to ERROR state on start_instance power_on failure | https://review.opendev.org/c/openstack/nova/+/984802 | |
| 12:40:08 | carloss | sean-k-mooney: yep, the change Uggla linked was an issue gouthamr ran into. but so far, in the scenario (end to end) tests I have implemented, no further bugs found | |
| 12:40:37 | carloss | this is a job run using manila's cephfs native: https://zuul.opendev.org/t/openstack/build/f761d9016979435abe69c849a645ebc2 | |
| 12:41:27 | carloss | I'm still figuring out why LVM (with NFS) is failing on CI because it's passing in a local env I have - so I think there's some mismatch in the env I own compared to the CI | |
| 12:41:57 | carloss | the share attachment tests are under the TestShareAttachmentCEPHFS class | |
| 12:44:36 | sean-k-mooney | Uggla: oh the resoume on host boot feature | |
| 12:45:00 | sean-k-mooney | ya im betting we didnt re attach the share or something? | |
| 12:45:04 | sean-k-mooney | that woudl have been easy to miss | |
| 12:48:22 | opendevreview | Merged openstack/nova master: objects: Prepare for oslo.versionedobjects 3.10.0 https://review.opendev.org/c/openstack/nova/+/985506 | |
| 12:54:31 | DominikDanelski[m] | sean-k-mooney: OK, so I propose that we split the change in 2: first the behaviour change without the signature change (extending the function's behaviour at the expense of making it long), then the split which would end in the current state. It would be hard to show the refactor without the reason it's being done (extending behaviour). | |
| 13:56:10 | opendevreview | Karol Klimaszewski proposed openstack/nova-specs master: Spec for SPDK-based nova-provisioned storage backend https://review.opendev.org/c/openstack/nova-specs/+/985676 | |
| 13:59:39 | tkajinam | as it's not likely we have time to discuss this... I wonder if that namespace package thing is what we broken when we removed pkg_resources ? | |
| 14:00:00 | tkajinam | I intended to keep that functionality but that was later broken by canonical folks insisting "this doesn't work for us" | |
| 14:00:43 | tkajinam | I might be confused by https://review.opendev.org/c/openstack/nova/+/939827 , though | |
| 14:01:20 | tkajinam | ok it seems nova.scheduler.filters has never been exposed as a namespace package | |
| 14:01:54 | tkajinam | we probably want to use the entrypoints approach instead | |

| 18:07:56 | cardoe | dansmith: I think my comments were misconstrued a little bit and I'd like to clear things up. | |
| 18:09:17 | cardoe | There's a number of users / operators of the nova-ironic driver that I'm aware of. That driver hasn't been a prime focus of the nova cores team so a lot of times patches kinda stall out a little bit. The testing for that driver in Zuul isn't the best as was highlighted during the call. | |
| 18:10:16 | cardoe | So what I'm doing is trying to get those users / operators to share some changes together that are important to them and trying to figure out the best way for us to voice that "this bug/issues is important to that group" | |
| 18:11:29 | cardoe | The reason for the repo idea is that more than once it's happened that I've spoken to one of them and they've said "oh we've iterated on the patch a little bit and use a new version". So just trying to come up with a way for them to do that more in the open. | |
| 18:17:52 | dansmith | cardoe: sounds pretty much like what you said on the call (although the context around it at the time is the important but). Sounds like a fork to me, which doesn't seem very constructive... | |
| 18:18:24 | dansmith | but, you don't need to convince me, I responded to your comment in the moment in the context of the moment | |
| 18:21:42 | cardoe | Can you give me suggestions how we get fixes that are important to the users of nova-ironic landed? | |

| 18:44:04 | melwitt | gmaan: dunno if you might be able to shed any light on this, but in CI the nova.tests.functional.test_servers.ServerMovingTestsWithNestedResourceRequests.test_resize_reschedule_uses_host_lists_3_fails test has been flaking out and I can't see why, | |
