| 16:38:33 | sean-k-mooney | its an imporant operational pain point | |
| 16:38:46 | sean-k-mooney | so i think its size is not the thing to focus on :) | |
| 16:39:11 | sean-k-mooney | Leo[m]: i have not looked at the spec yet | |
| 16:39:22 | sean-k-mooney | but the main aspect i would ask is how do we upgrade to this | |
| 16:39:30 | sean-k-mooney | per host config options are not a good path | |
| 16:39:36 | sean-k-mooney | at least not long term | |
| 16:39:42 | sean-k-mooney | as they cause issues with live migration | |
| 16:39:54 | sean-k-mooney | but ya we can work out those details later | |
| 16:39:57 | Uggla | Leo[m] usually we discuss topic at PTG and then the changes are reviewed. | |
| 16:40:33 | Leo[m] | What do you mean by "per host config options"? | |
| 16:40:48 | Leo[m] | Sounds good. Does that mean I should prepare the PR now? | |
| 16:41:21 | sean-k-mooney | ideally we woudl not bave a boolen config flage to opt into using the hostname | |
| 16:41:26 | sean-k-mooney | ```As currently proposed, one config option will be added | |
| 16:41:28 | sean-k-mooney | (a boolean in ``[libvirt]``, default ``False``) that allows operators | |
| 16:41:30 | sean-k-mooney | to opt in to using hostnames for the mon addresses``` | |
| 16:41:51 | Uggla | only spec is required, but if you have a "draft" patch that something helpful. | |
| 16:42:54 | sean-k-mooney | nova get the ceph mon info from the ceph.conf | |
| 16:43:23 | Leo[m] | Ok, great. Thank you for your help. Is there a link to information about the PTG and its agenda? | |
| 16:43:25 | sean-k-mooney | so ideally the mon adresses there woudl jsut eb updated to the fqdn and nova would "just work" | |
| 16:44:04 | sean-k-mooney | note that nova access ceph in 2 ways | |
| 16:44:05 | Uggla | Leo[m] https://etherpad.opendev.org/p/nova-2027.1-ptg | |
| 16:44:22 | sean-k-mooney | we use the ceph cli and the pythyon bi9nding so we need a coherent story for both | |
| 16:44:41 | tkajinam | put your topic at the bottom | |
| 16:46:07 | sean-k-mooney | so in the interest of time, are we ok with updateign https://blueprints.launchpad.net/nova/+spec/support-vfio-variant-driver-managed-mode-via-cyborg to 2027.1 and seting it back to approved? | |
| 16:46:46 | sean-k-mooney | Uggla: you marked it as implemnted on last week but i reset it because its still in progress hence its current state | |
| 16:46:57 | Uggla | sean-k-mooney ok | |
| 16:47:11 | gibi_ | sean-k-mooney: any findings from the original plans during the implementation? | |
| 16:47:21 | Uggla | so I might have write something wrong in HL/prelude. | |
| 16:47:42 | sean-k-mooney | gibi_: just that the cybrog side needed me to implment ovo indirection api.. | |
| 16:48:06 | sean-k-mooney | gibi_: i realised late that we didnt have that in cybrog so i paused the work to focus on other features | |
| 16:48:06 | gibi_ | sean-k-mooney: ack that probably not affecting nova :) | |
| 16:48:33 | sean-k-mooney | so my plan is to complete the cybrog work includign ci then update the nova patch once im happy with all of that | |
| 16:49:14 | sean-k-mooney | im not expecting any scope change on the nova side for this specificly | |
| 16:49:37 | sean-k-mooney | i hae some ptg topic like using the sdk to talk to cybrog proerply | |
| 16:49:43 | sean-k-mooney | but that independint of this feature | |
| 16:49:45 | gibi_ | sean-k-mooney: sounds good to me | |
| 16:50:06 | gibi_ | Uggla: if this is in the prelude and highlight the we need to get remove it :) | |
| 16:50:37 | sean-k-mooney | i dont htink this is is there | |
| 16:50:48 | sean-k-mooney | i think we called out the mdev support | |
| 16:50:51 | sean-k-mooney | that did merge | |
| 16:50:58 | sean-k-mooney | so the nvidia drvier in thery shoudl now work | |
| 16:51:26 | Uggla | yep but I extended with variant because I thought it was merged. | |
| 16:51:56 | sean-k-mooney | oh ok | |
| 16:52:01 | sean-k-mooney | almost but not quite | |
| 16:53:01 | sean-k-mooney | ah i see https://docs.openstack.org/releasenotes/nova/2026.2.html | |
| 16:53:10 | sean-k-mooney | ya i can push a fix for that if you want | |
| 16:53:48 | sean-k-mooney | well this is the current text | |
| 16:54:01 | sean-k-mooney | ```Nova’s libvirt driver now supports Cyborg-managed mediated devices (such as vGPUs) via a new MDEV accelerator request binding type. Operators can choose to manage vGPU/mdev lifecycle through Cyborg as an alternative to Nova’s native support. Both management paths coexist safely thanks to a new OWNER_NOVA trait that prevents scheduling collisions between Nova-managed and | |
| 16:54:03 | sean-k-mooney | Cyborg-managed devices.``` | |
| 16:54:16 | sean-k-mooney | that does not mention manage mode | |
| 16:54:19 | sean-k-mooney | so i think we are good | |
| 16:55:09 | Uggla | yep | |
| 16:55:37 | gibi_ | cool then | |
| 16:55:49 | sean-k-mooney | ok so jsut to be clear gibi_ Uggla are you ok with markign this as approved again for this cycle | |
| 16:56:00 | Uggla | yep | |
| 16:56:03 | sean-k-mooney | if so we can move on/finsh up for this week | |
| 16:56:08 | gibi_ | 6yepp | |
| 16:56:27 | sean-k-mooney | cool thanks | |
| 16:56:30 | gibi_ | one queston before we stop | |
| 16:57:04 | gibi_ | are we then OK no to have an RC2 for the os-vif change being bumped into nova's min requirements? | |
| 16:57:37 | sean-k-mooney | we could its not stricly needed but i dont object | |
| 16:57:57 | gibi_ | https://review.opendev.org/c/openstack/os-vif/+/1005496 | |
| 16:58:08 | sean-k-mooney | that a diffent question | |
| 16:58:27 | sean-k-mooney | your asking are we ok requestign a lib freeze excption for os-vif | |
| 16:58:39 | sean-k-mooney | a min verison bump in nova would not pick that up | |
| 16:58:42 | sean-k-mooney | since its not released | |
| 16:58:56 | gibi_ | I'm asking, does we as the compute team needs to anyting with this in connection with the Hibiscus GA :) | |
| 16:59:35 | sean-k-mooney | :) it would be nice to have but could come later, neutron would like for that to be backported and released | |
| 16:59:44 | sean-k-mooney | here is the backport https://review.opendev.org/c/openstack/os-vif/+/1005591 | |
| 17:00:21 | sean-k-mooney | doing an early release or asking for an expction work for me | |
| 17:00:35 | sean-k-mooney | early meaing in early october when the lib freeze lifts | |
| 17:02:30 | sean-k-mooney | oh good/bad timeing not sure how muhc of that gibi_ saw | |
| 17:02:47 | gibi | not much | |
| 17:02:54 | gibi | i started lagging again | |
| 17:02:59 | Uggla | 2nd option looks simpler. | |
| 17:03:02 | gibi | and reconnect took time | |
| 17:03:14 | sean-k-mooney | so second option is we merge the backport | |
| 17:03:26 | sean-k-mooney | and propsoe the release wehn we are allowed too in early october | |
| 17:03:34 | sean-k-mooney | but dont need to do anything else now | |
| 17:03:58 | gibi | OK | |
| 17:04:02 | gibi | that works for me | |
| 17:04:04 | Uggla | I'm ok with that. | |
| 17:04:11 | gibi | if nobody objects then this is cheap | |
| 17:04:27 | gibi | thanks | |
| 17:04:30 | gibi | I have nothing further | |
| 17:04:32 | sean-k-mooney | gibi: if your internet coperates this is the backport https://review.opendev.org/c/openstack/os-vif/+/1005591 | |
| 17:04:38 | gibi | sure | |
| 17:04:50 | gibi | only IRC is problematic which is strange | |
| 17:04:53 | elodilles | sounds OK to me with my relmgt core hat on d:) | |
| 17:05:07 | sean-k-mooney | even better :) | |
| 17:05:14 | Uggla | ok so I think we are done for today. | |
| 17:05:17 | sean-k-mooney | +1 | |
| 17:05:41 | Uggla | Thanks for joining this meeting. Have a nice day/evening. | |
