15:25:45	elodilles	Uggla: can you update your -1 on the patch? what you add there will show up in the metadata of the tag o:) https://review.opendev.org/c/openstack/releases/+/982438
15:29:44	Uggla	elodilles, wrapup what we have said here in the comment and +1 it.

16:00:12	Uggla	Hello everyone
16:00:18	elodilles	o/

16:03:22	Uggla	Let's start hopefully other folks will join shortly.
16:03:31	Uggla	#topic Bugs (stuck/critical)
16:03:36	Uggla	#info No Critical bug
16:03:45	sambork	o/
16:03:55	Uggla	hey sambork, hi !
16:04:13	Uggla	#topic Gate status
16:04:20	Uggla	#link https://bugs.launchpad.net/nova/+bugs?field.tag=gate-failure Nova gate bugs

16:04:40	Uggla	#info Please look at the gate failures and file a bug report with the gate-failure tag.
16:04:46	Uggla	#info Please try to provide a meaningful comment when you recheck
16:05:09	Uggla	I have not seen something special around the gate, please tell me if I'm wrong.
16:05:19	gibi	o/
16:05:26	gibi	Uggla: I also checked this morning
16:05:48	gibi	as on Friday we switched the nova-compute default to native threading
16:06:01	Uggla	gibi, something frightening I missed ?
16:06:05	gibi	but I haven't seen any suspicious failure in nova or in neighboring project
16:06:28	gibi	Uggla: it is frightening but so far the monster remained in the woods
16:06:46	gibi	I keep an eye on it
16:07:10	Uggla	It also means that G release will not have this enabled right ?
16:07:19	gibi	right, it is H
16:07:31	gibi	where we switched the default for compute and conductor
16:07:42	gibi	in G for these the default is eventlet still
16:07:53	Uggla	Yep I saw that this morning looking at the latest patches.
16:08:40	bauzas	o/ (late)
16:08:43	Uggla	Yep, so I will tell that in the highlight. G = eventlet, H = native threads
16:08:43	Uggla	So that it is coherent with G as experimental
16:08:53	gibi	yepp
16:09:11	gibi	for compute and conductor
16:09:22	gibi	for api, metadata and scheduler F=eventlet G=native
16:10:10	Uggla	ah yes it is a bit more complex, but perfectly cleat now. So I should not say something wrong in the highlights.
16:10:11	gibi	https://docs.openstack.org/nova/latest/admin/concurrency.html
16:10:19	gibi	if you ever in doubt ^^
16:10:26	Uggla	👍
16:10:36	Uggla	anything else about gate ?
16:10:41	gibi	-
16:10:59	Uggla	So moving on to the next topic
16:11:10	Uggla	#topic Release Planning
16:11:23	Uggla	#link https://releases.openstack.org/gazpacho/schedule.html
16:11:29	Uggla	#info Nova deadlines are set in the above schedule
16:11:35	Uggla	#info PTG etherpad for 2026.2 is available: https://etherpad.opendev.org/p/nova-2026.2-ptg
16:11:42	Uggla	#info This is a "work in progress document", but you can enter you topics at the bottom of the document
16:12:00	Uggla	#info Gazpacho should release this week.
16:12:12	Uggla	#info we will discuss Hibiscus release planning at the PTG.
16:12:26	Uggla	#info Gazpacho Openstack Infra live this week, Thursday 2nd april 14:00 UTC
16:12:27	gibi	there is a tentative plan at https://releases.openstack.org/hibiscus/schedule.html
16:13:16	Uggla	yeah gibi is right, there is a "draft" plan that we will adjust at the PTG.
16:13:43	Uggla	#topic Review priorities
16:13:51	Uggla	#link New file for Hibiscus https://etherpad.opendev.org/p/nova-2026.2-status
16:14:01	Uggla	#info I have updated Launchpad and the above doc. Please ping me if you spot something missing.
16:14:11	Uggla	#info Starting: https://etherpad.opendev.org/p/nova-2026.2-status#L16 interesting bugs to review.
16:14:49	Uggla	I have reviewed topic:"bp/generalize-sev-code", gibi any chance you review it again ?
16:15:24	gibi	Uggla: on my list among other things
16:15:51	Uggla	gibi ok no pb
16:16:12	Uggla	tkajinam, thanks for your answer on the ML for AMD-SNP.
16:16:43	tkajinam	Uggla, np
16:17:30	Uggla	Do you think you can have a draft spec to discuss at PTG ? And then give the hand for refinement and implementation to someone else ?
16:17:50	tkajinam	yeah I can
16:17:59	tkajinam	I also had a chat with some folks from LY regarding sev-snp and they told me that they already created their own implementation.
16:18:29	tkajinam	I guess they are also preparing spec in their side. I'll check it with them in case they are ready to submit their version
16:18:41	Uggla	super cool, thanks. And interesting to know that people for LY corp already have something.
16:18:56	Uggla	Any chance to have a joined spec ?
16:18:59	tkajinam	masahito, just fyi ^^^
16:19:07	tkajinam	yeah I think that's better
16:20:33	gibi	just to my limited brain capacity, so this means tkajinam will help with the spec (joint or not) but we need somebody who takes over and implements it
16:20:41	gibi	is it a correct understanding?
16:20:53	Uggla	gibi, yes
16:20:56	gibi	OK
16:21:25	Uggla	Anton will work on the TDX implementation though.
16:22:25	gibi	I feel that even with the refactoring we have a chance that the TDX and the SNP work will merge conflict, do we have some mitigation planned, or we just use the first come first server rule?
16:22:47	Uggla	Noob question regarding HW, what is supporting AMD-SNP ? Special AMD CPUs ?
16:22:57	sean-k-mooney	on the topic of the PTG we likely need to schdule a cyborg cross project session but i have not formulated a specific adgenda yet.
16:23:04	tkajinam	Technically I can provide a draft code but I may not have enough time to set up test environment for it. (due to my focus shifting away from these confidential computing things atm)
16:23:15	sean-k-mooney	Uggla: not specificly specil but ranter a specific genreation
16:23:16	tkajinam	Uggla, yeah you need specific generation of EPYC processor which supports SEV-SNP
16:23:34	sean-k-mooney	as in i think you need 3rd generation EPYC or later
16:23:41	tkajinam	and relatively new kernel + qemu + libvirt, which actually supports host features to use SEV-SNP
16:23:42	tkajinam	yeah
16:24:15	sean-k-mooney	i woudl need to check but i think we have access interenaly to at least 1 AMD host that supprot SNP
16:24:16	Uggla	ok gonna check what is required in term of HW, to know if we have host supporting it.
16:25:06	tkajinam	gibi, I agree these two can cause conflict but I guess the conflict can be easily resolved because we don't expect object change.
16:25:13	Uggla	gibi, regarding the merge conflic, I expect a lot from the refactoring to limit them.
16:25:23	gibi	OK
16:25:41	Uggla	but we will see.
