lajoskatonaUggla: Hi, as nova meeting time in CEST is 1800, I can only attend the first ~20 minutes, from my side I worked/working on the patch for migrating security-groups to SDK, so some progress with it :-)15:00
UgglaNova upstream meeting in ~1h15:05
Ugglalajoskatona, do you want me to schedule your point early today ?15:06
Ugglaelodilles ok I agree it is not fundamental to have this commit.15:13
lajoskatonaUglla: thanks, I don't want to mess up the Nova meeting, I have only that short update I wrote earlier15:16
Ugglaok15:18
elodillesUggla: +115:22
elodillesUggla: 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/+/98243815:25
Ugglaelodilles, wrapup what we have said here in the comment and +1 it.15:29

Uggla         #info Please try to provide a meaningful comment when you recheck16:04
UgglaI have not seen something special around the gate, please tell me if I'm wrong.16:05
gibio/16:05
gibiUggla: I also checked this morning16:05
gibias on Friday we switched the nova-compute default to native threading16:05
Ugglagibi, something frightening I missed ?16:06
gibibut I haven't seen any suspicious failure in nova or in neighboring project16:06
gibiUggla: it is frightening but so far the monster remained in the woods16:06
gibiI keep an eye on it16:06
UgglaIt also means that G release will not have this enabled right ?16:07
gibiright, it is H 16:07
gibiwhere we switched the default for compute and conductor16:07
gibiin G for these the default is eventlet still16:07
UgglaYep I saw that this morning looking at the latest patches.16:07
bauzaso/ (late)16:08
UgglaYep, so I will tell that in the highlight. G = eventlet, H = native threads16:08
UgglaSo that it is coherent with G as experimental16:08
gibiyepp16:08
gibifor compute and conductor16:09
gibifor api, metadata and scheduler F=eventlet G=native16:09
Ugglaah yes it is a bit more complex, but perfectly cleat now. So I should not say something wrong in the highlights.16:10

Uggla👍16:10
Ugglaanything else about gate ?16:10
gibi-16:10
UgglaSo moving on to the next topic16:10
Uggla#topic Release Planning16:11
Uggla#link https://releases.openstack.org/gazpacho/schedule.html16:11
Uggla#info Nova deadlines are set in the above schedule16:11
Uggla#info PTG etherpad for 2026.2 is available: https://etherpad.opendev.org/p/nova-2026.2-ptg16:11
Uggla#info This is a "work in progress document", but you can enter you topics at the bottom of the document16:11
Uggla#info Gazpacho should release this week.16:12
Uggla#info we will discuss Hibiscus release planning at the PTG.16:12
Uggla#info Gazpacho Openstack Infra live this week, Thursday 2nd april 14:00 UTC16:12
gibithere is a tentative plan at https://releases.openstack.org/hibiscus/schedule.html16:12
Ugglayeah gibi is right, there is a "draft" plan that we will adjust at the PTG.16:13
Uggla#topic Review priorities16:13
Uggla#link New file for Hibiscus https://etherpad.opendev.org/p/nova-2026.2-status16:13
Uggla#info I have updated Launchpad and the above doc. Please ping me if you spot something missing.16:14
Uggla#info Starting: https://etherpad.opendev.org/p/nova-2026.2-status#L16 interesting bugs to review.16:14
UgglaI have reviewed topic:"bp/generalize-sev-code", gibi any chance you review it again ?16:14
gibiUggla: on my list among other things16:15
Ugglagibi ok no pb16:15
Ugglatkajinam, thanks for your answer on the ML for AMD-SNP.16:16
tkajinamUggla, np16:16
UgglaDo 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
tkajinamyeah I can16:17
tkajinamI also had a chat with some folks from LY regarding sev-snp and they told me that they already created their own implementation.16:17
tkajinamI guess they are also preparing spec in their side. I'll check it with them in case they are ready to submit their version16:18
Ugglasuper cool, thanks. And interesting to know that people for LY corp already have something. 16:18
UgglaAny chance to have a joined spec ?16:18
tkajinammasahito, just fyi ^^^16:18
tkajinamyeah I think that's better16:19
gibijust 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 it16:20
gibiis it a correct understanding?16:20
Ugglagibi, yes 16:20
gibiOK16:20
UgglaAnton will work on the TDX implementation though.16:21
gibiI 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
UgglaNoob question regarding HW, what is supporting AMD-SNP ? Special AMD CPUs ?16:22
sean-k-mooneyon the topic of the PTG we likely need to schdule a cyborg cross project session but i have not formulated a specific adgenda yet. 16:22
tkajinamTechnically 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
sean-k-mooneyUggla: not specificly specil but ranter a specific genreation 16:23
tkajinamUggla, yeah you need specific generation of EPYC processor which supports SEV-SNP16:23
sean-k-mooneyas in i think you need 3rd generation EPYC or later16:23
tkajinamand relatively new kernel + qemu + libvirt, which actually supports host features to use SEV-SNP16:23
tkajinamyeah16:23
sean-k-mooneyi woudl need to check but i think we have access interenaly to at least 1 AMD host that supprot SNP16:24
Ugglaok gonna check what is required in term of HW, to know if we have host supporting  it.16:24
tkajinamgibi, 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
Ugglagibi, regarding the merge conflic, I expect a lot from the refactoring to limit them.16:25
gibiOK16:25
Ugglabut we will see. 16:25
UgglaI think we are done with that topic.16:26
UgglaAnd yes sean-k-mooney, we can work together to have a cross session with cyborg.16:27
UgglaFYI, I will be on PTO next week, but back 1 week before PTG to prepare it.16:28
Ugglaok moving on to next topic16:28

elodilles#info nova stable gates should be OK16:29
elodilles#info placement and osc-placement have blocked stable gates, fixes need stable cores review (see: https://review.opendev.org/q/topic:pin-setuptools-81-docs and https://review.opendev.org/q/topic:pin-setuptools-81-via-virtualenv-pkg-resources )16:29

gibifwiesel: thanks16:32
gibiI will keep an eye on our WIP16:33
fwieselIt takes more time, because a couple of other problems happened. (Such as expired certificates)16:33
fwieselI'll be on PTO on next Monday, so I can report back on the Monday after that16:33
gibifwiesel: OK, have a good PTO16:33
fwieselBut I am optimistic, I can validate the fix this week.16:33

Uggla?16:40
sean-k-mooneyfor a series like that we proably dont want this to be all or nothing. so it might be worth seeing fi we can land some of the eaierl patches. which that said i have not looked at it in at least a release16:40

gibi-16:54
sean-k-mooneynot really16:54
Ugglaok so time to close.16:56
womax_Hi, I finally had time to come back and update a spec for tempURL usage in nova (came here to talk about it a few months ago). Would like to know if I could have some review to it, or as ptg are coming it would have to wait for them16:56
womax_https://review.opendev.org/c/openstack/nova-specs/+/97588316:56
Ugglawomax_ please add a topic the ptg doc, I will find a slot to discuss it16:56
womax_ok thx, where do i find the doc?16:57
Ugglahttps://etherpad.opendev.org/p/nova-2026.2-ptg16:57
sean-k-mooneywomax_: skiming it im not sure why nova need to change exactly16:58
sean-k-mooneyif i cant tell that after 90s of lookign at the spec it means you need to motivate the problem statemenadn user case better in the spec16:58
womax_sean-k-mooney need to make a few modifications to use the feature it is implemented in glance16:58
sean-k-mooneybut why16:58
sean-k-mooneynova does not need ot use every glance fature that is added16:59
sean-k-mooneyyou need to explin in the spec what benift this ahs to users and adminstiartor of nova16:59
womax_oh ok in this sense16:59
womax_to be short, dessaturate glance traffic by bypassing it when download image16:59
womax_I'll add it17:00
sean-k-mooneyyep so in the specific case that we are using swift/s3 or ceph rados gateway17:00
womax_yes17:00
sean-k-mooneyif glacne implenmt that feature we coudl use a direct temp url to download the iamge instead of streaming via glance17:01
womax_yes exactly17:01
sean-k-mooneybut it woudl be good to explain that  up front17:01
sean-k-mooneyanyway we are at time but it woudl also be good to capture how nova woudl knwo to use this in the spec17:01
sean-k-mooneyi.e. if we have a glance multi store env how do we know which stores supprot it and which do nto17:02
sean-k-mooneyectra so that the nova spec is mostly self contaiened17:02
Ugglayep we need to close.17:02
womax_ok i'll think more about it17:02
UgglaDiscussion can be done later outside of the meeting.17:02
womax_and we can discuss later17:02
UgglaThanks for joining this meeting. Have a nice day/evening and see you in 2 weeks.17:03

elodillesthanks o/17:03
sean-k-mooneywomax_: have you recived much feedback on the glance spec. is it a new proposal on that side?17:04
opendevreviewMerged openstack/placement stable/2024.2: [CI][stable-only] Workaround for missing pkg_resources  https://review.opendev.org/c/openstack/placement/+/97964217:05
womax_sean-k-mooney i already have had feedback from glance, it is indeed a new proposal17:05
sean-k-mooneymy expecation is that either this new feature would return the tempurl in the same location as the current glance api path in the image locations api or there will be a new microversion and api endpoint to requst a temp url and some way for nova to discover if that is supprroted for a given glance store?17:06
womax_we had a bit of discutions around security concern, but consensus was to know if nova would be interested in such use case before having further discutions17:06
womax_feature spec can be found here https://review.opendev.org/c/openstack/glance-specs/+/97021417:07
womax_for the time i proposed a 2 new api path one for receiving tempURL (useful for ironic) and one that returns a redirection with nova in mind17:08
womax_and updating stores details to reflect if store has the capabilities and enabled17:08
sean-k-mooneyare these tempurls 1 time use? or time based17:09
womax_time based17:09
sean-k-mooneyack im askign incase we need to rety the download17:09
sean-k-mooneyi think we allwo up to 3 tries today17:10
womax_retry could work, expirations time would juste had to be configured accordingly17:10
womax_to not expires too soon17:10
sean-k-mooneywomax_: out of interest what is your primary storage backend for images17:12
womax_s317:12
womax_too be precise s3 compatible17:12
sean-k-mooneywell that what im trying to udnerstadn 17:12
sean-k-mooneyits not ceph radows gateway right17:12
womax_no17:13
sean-k-mooneyits minio or some other not swrit not ceph s3 compatibale storage17:13
womax_yes 17:13
womax_it's the s3 compatible storage we offered in public cloud at ovh17:13
sean-k-mooneyack the reason im asking is that is not one fo the case were we can already optmize out the storage tansfer17:14
sean-k-mooneywomax_: to me this feels more like the type of optimisation we do for rbd where we use the image location api to provide a driect rbd url17:14
sean-k-mooneybut restict ti to admin/service users17:15
sean-k-mooneynot normal users17:15
sean-k-mooneyso normal user use the glance api17:15
sean-k-mooneybut service like ironic and nova cna get the direct backend storage url and if they supprot it use that directly17:15
womax_ok for nova i could dig around direct backend, it could solve our problems17:16
sean-k-mooneyso how the rbd direct download works is if you have it enabel and have the rbd credtial for that sotre we use the ceph client to do the download directly17:17
sean-k-mooneyskiping the streaming via the glance api when the host is using say qcow2 for its nova provisioned storage17:17
sean-k-mooneythat effectivly the same problem statemnt17:17
womax_yeah that would indeed be a solution to what we want, but i assume there is no current equivalent for backend like s3 / swift already done?17:18
*** ChanServ sets mode: +o Uggla17:18
sean-k-mooneynova is suing qcow2, image is in s3 compaitbale storage have nova take an optimised path if it has been configured to supprot that adn galace can prove either a direct buket link or tempurl 17:18
sean-k-mooneycorrect that does not exist17:18
sean-k-mooneyyou coudl do either either by provie nova the s3 credital used by glance or via the tempurl you are suggesting then with jsut a http client17:19
sean-k-mooneywomax_: https://specs.openstack.org/openstack/nova-specs/specs/victoria/implemented/nova-image-download-via-rbd.html 17:20
sean-k-mooneythat was the rbd oen17:20
sean-k-mooneyyou could  add a new direct_url_scheme in glance 17:20
womax_providing s3 credentials to every hosts seems a bit dubious, it seems too large to distribute credentials17:20
sean-k-mooneyallowed_direct_url_schemes=tempurl17:20
womax_so temp url seems a bit more appropriate17:20
sean-k-mooneywomax_: i mean yes an no we od it for cpeh17:21
womax_ok didn't know about it17:21
sean-k-mooneythere isnt a tempurl schema today17:22
sean-k-mooneyim just sayign this migh be a way to achive the same goal folowing the established patterens17:22
womax_and, for context i started digging tempURL as I did some changes in ironic that currently generates temp url on it own, and would have like to centralize it in glance, and then i came back to nova as a potential user17:23
womax_but yeah i will dig into how it is done for rbd and see how i could have something similar17:23
