#openstack-nova - 2025-10-28
16:37:53 sean-k-mooney clarkb: i normlaly use chrom for all webrtc stuff like google meet but it also could be on my side, i have intrusion detection enabeld on my ubiquit router
16:38:06 sean-k-mooney althoug given firefox is fine its proably not that
17:02:50 cardoe Uggla: I've put https://review.opendev.org/c/openstack/nova-specs/+/471815 at the end of the agenda... still wondering how we can make this happen
17:03:17 cardoe There's code for the spec. There's tests for the spec. There's multiple downstream vendors that have been running the patches in production for over a year now.
17:03:36 Uggla cardoe, I will find a slot tomorrow morning my time and I will keed you update.
17:03:45 Uggla *keep
17:05:26 cardoe Uggla: happy to do it around the time of the ironic/nova cross project times since I'm representing Ironic for both cross project topics.
17:06:20 Uggla yep I was thinking of it. Because the Ironic session is quite long. So maybe you'll have a timeslot.
18:34:58 sean-k-mooney Uggla: we shoudl update the ptg bot to say we are don for today
18:35:31 sean-k-mooney clarkb: what is the channel again for the ptg is it opendev-events or something generic for that?
18:35:33 Uggla sean-k-mooney, I was doing it when I see your msg poping
18:35:39 Uggla :)
18:35:40 sean-k-mooney :)
18:36:01 clarkb sean-k-mooney: its #openinfra-events
18:37:09 sean-k-mooney ah its openinfra
18:37:17 sean-k-mooney i tried opensdev and openstack
19:38:15 BigToeTuna Hi friends. I have a quick inquery, I have a use case which requires growing the instances directory mountpiont on the hypervisor. However I can achieve this by having multiple instances_paths I.E /var/lib/nova/instances0, /var/lib/nova/instances1 and so on. Is there any way to specify multiple instance directories?
20:01:13 dansmith nope
20:13:41 BigToeTuna I figured, thanks!

07:40:06 yunhokim_ Hi, compute_task.migrate_server notification has sent as error when vm migration failed due to lack of host. But resize also use same notification and payload. Can we add delimiter in payload to figure out which event occurs during migration or resize?
08:46:46 gibi yunhokim_: resize and cold migrate is the same action internally in nova. A cold migrate is a resize without flavor change. The instance.resize_prep.start and instance.resize_prep.end notifications has an extra new_flavor field. If you compare the flavorid in the new_flavor and flavor fields and they are differ then the it is a resize, if they are the same then it is a cold migration. At the moment
08:46:52 gibi this is the best we can do. If you want to improve on it we might be able to add the new_flavor fields to the rest of the resize notifications
09:59:44 yunhokim_ Thanks for apply. I just find the code that you mentioned from conductor. I will check that can improve.
11:20:37 iurygregory Hello nova folks, just a reminder that today at 15:30 UTC we have cross-project session with ironic, where? Mitaka room
12:00:05 sean-k-mooney https://etherpad.opendev.org/p/nova-2026.1-ptg#L93
12:00:20 sean-k-mooney iurygregory: it says nova host in the grizzly room
12:00:46 sean-k-mooney iurygregory:but that really means join https://meetpad.opendev.org/nova-2026.1-ptg
12:01:32 sean-k-mooney since we are not using zoom rooms and are usign the meetpad/jitis rooms instead
12:12:08 iurygregory sean-k-mooney, oh ok!
12:13:47 sean-k-mooney iurygregory:oh uyou sadi 15:30
12:13:54 sean-k-mooney iurygregory: for that we are in your room
12:13:57 sean-k-mooney https://etherpad.opendev.org/p/nova-2026.1-ptg#L104
12:14:13 sean-k-mooney i looked at teh mainilla session sorry
12:14:25 iurygregory oh ok
12:14:32 sean-k-mooney iurygregory: so we shoudl be joining https://meetpad.opendev.org/oct2025-ptg-ironic at 15:30
12:14:37 iurygregory yeah
12:14:59 iurygregory I will join the nova room to remind about it
12:15:09 sean-k-mooney oh you were not askign where it is you were saying it was in mitaka before
12:15:24 iurygregory yeah =)
12:16:35 sean-k-mooney iurygregory: so im proably still going ot be in the watcher room at that point so i likely wont be able to attend but i think i replied in supprot fo the ironic topic on the ml? unless im misrememebring
12:17:02 sean-k-mooney iurygregory: the restore backups to a different availability zone topic if for cinder right?
12:17:11 iurygregory sean-k-mooney, you did
12:17:35 sean-k-mooney given you cant use AZ with ironic really since you cant really use host aggartes with ironic
12:17:42 sean-k-mooney on the nova side
12:18:16 sean-k-mooney its proably less broken then it was in the past now that we supprot the ironic sharding feature
12:18:18 iurygregory yeah, we only have two topics the graphical console and boot the machines from NVMe-over-TCP (nova+cinder)
12:18:27 sean-k-mooney cool
12:18:48 iurygregory feel free to add info in the etherpad if you want also
12:18:55 iurygregory https://etherpad.opendev.org/p/ironic-ptg-2026.1#L667
12:19:23 sean-k-mooney iurygregory: this might be of relevence to ironichttps://review.opendev.org/c/openstack/nova-specs/+/471815
12:20:06 iurygregory sean-k-mooney, for which topic?
12:20:14 sean-k-mooney although that more about supproting the vlan trunk info for neutron trunk ports in genreal in the metadata
12:20:54 sean-k-mooney iurygregory: not for any of the current ones it just hat mentionign it because one of the use cases is "Once the BM server is booted up with Ironic, its networking interfaces can be
12:20:56 sean-k-mooney automatically configured and brought up."
12:21:34 sean-k-mooney iurygregory: i belive ye implented a feature very much like this on your side in the last release or twoo so this may now onlybe relevent to other virt drivers
12:21:40 sean-k-mooney just sharing for awareness
12:26:35 iurygregory ack
12:26:46 iurygregory tks sean-k-mooney
12:26:52 iurygregory fyi TheJulia ^
12:49:41 TheJulia cardoe: w/r/t the spec sean mentioned, any n-g-s impact anticipated?
12:50:19 cardoe The vlan trunk? No
12:50:40 cardoe We run the patches and Mirantis runs the patches in prod for well over a year.
12:50:42 TheJulia but shouldn't there be switch configuration to represent it?
12:51:11 cardoe Of course. But this is about passing the trunk port data to the server so it knows how to configure its interfaces.
12:51:46 sean-k-mooney TheJulia: the vlan that is presented to the guest is a public atibute of neutorn turnk prot api meaning the end user get to choose it
12:51:46 cardoe This is just representing what’s in neutron to the server.
12:51:57 sean-k-mooney n-g-s would have to cofnigure that mapping on the switch port
12:52:12 sean-k-mooney but that seperate form passing the infor to the vm in the metadta
12:52:21 cardoe Exactly
12:54:12 TheJulia Okay, looks like there is already code there to handle trunks specifically
12:54:13 cardoe TheJulia: https://github.com/openstack/networking-generic-switch/blob/master/networking_generic_switch/trunk_driver.py
12:54:22 cardoe There's the implementation of n-g-s handling it already.
12:54:34 TheJulia yeah, I found that and in the mech driver, I just haven't had time and caffination to compeltely wrap my head around it so far this morning
12:54:57 TheJulia Anyway, thanks for the quick responses!
12:55:19 cardoe Yeah we implemented this ages ago in there.
12:55:38 cardoe Along with tests and tests for tempest which depend on the change to nova.
12:56:37 cardoe There’s additional tests for neutron as well and bug fixes for some corner cases with neutron and its trunk handling.
12:56:41 TheJulia ... yeah, I remember now
12:56:49 TheJulia I had to fix the tests from blindly running
12:57:22 cardoe Neutron accepted the change to tighten up the spec on their side as well.
12:58:49 cardoe It was a series of patches developed by Mirantis, Red Hat and another company. The unnamed company is who I pressed on their CTO to stop developing OpenStack downstream and get involved upstream. To pus their developers to join the projects.
13:00:48 cardoe I naively said I just got elected to the TC. Let me show you how it’s not hard to engage the community and get a benefit from that. I thought this has a spec and patches written by a group covering multiple companies. It’ll be easy.
13:02:45 cardoe I pointed the CTO to asks by projects for more people to get engaged. He told me their work just gets ignored. I thought I could get more developers to engage nova and neutron.
13:03:19 cardoe I was proven wrong.
13:42:41 Uggla Info: Start of PTG session in ~20mn
13:42:50 Uggla Topic: Discuss if the CPU comparison beetween src host and dst host can not be improved or is it still relevent ?
14:03:22 nisha04 uggla: Hi regarding the session schedule on etherpad. Japan morning with US folks also works for me. I can also join the original PTG timeslot (14:00 to 18:00 UTC) on Thu/Fri if the morning session is difficult. What do you think?
14:50:35 nicolairuckel How can I see which room I have to join for my topic?
14:50:44 nicolairuckel For the PTG
14:51:27 nicolairuckel Uggla, do I just join the Nova room?
14:51:39 auniyal https://ptg.opendev.org/ptg.html -
14:51:46 auniyal you can join here https://meetpad.opendev.org/nova-2026.1-ptg
14:52:11 nicolairuckel thanks!
14:52:21 Uggla nicolairuckel, yes please join using the link above from auniyal
14:52:38 Uggla We are still in the cinder/nova x team session.
15:41:39 opendevreview melanie witt proposed openstack/nova master: libvirt: add configuration option for volume AIO mode https://review.opendev.org/c/openstack/nova/+/964848
15:46:06 opendevreview melanie witt proposed openstack/nova master: libvirt: add configuration option for volume AIO mode https://review.opendev.org/c/openstack/nova/+/964848
16:05:17 dansmith Uggla: man, feels like this is not the best use of nova's time, eh?
16:07:37 Uggla dansmith it was not what was expected.
16:08:25 Uggla cinder should join later.
