04:52:59 alex_xu HagunKim: ah
04:53:11 alex_xu HagunKim: probably you only can manually delete
04:53:29 alex_xu HagunKim: why there are duplicated data?
04:56:42 HagunKim alex_xu: Well.. I don't know why. But there are datas with same id value.

07:26:04 ileixe Hi nova!
07:26:42 ileixe Does anybody has an environment which assure CPU QoS within Nova?
07:27:18 ileixe I mean have anybody ever used CPU pinning in production or something else to prevent noisy neighbors?
07:28:16 ileixe I want to hear any experience which will be really appreciated for us
07:58:57 openstackgerrit ya.wang proposed openstack/nova master: Support reporting multi CPU model traits https://review.opendev.org/670300
08:19:55 openstackgerrit Matthew Booth proposed openstack/nova master: libvirt: Fix service-wide pauses caused by un-proxied libvirt calls https://review.opendev.org/677736
08:34:18 openstackgerrit Brin Zhang proposed openstack/nova master: Add delete_on_termination to volume-attach API https://review.opendev.org/673133
09:15:31 stephenfin alex_xu: Well, you can't migrate pinned instances at the moment anyway, so that's not an issue :)
09:16:10 stephenfin alex_xu: However, assuming artom fixes it, we have that option to disable the translation feature in the scheduler
09:16:27 stephenfin alex_xu: So if the operator sets that, the scheduler will keep requesting VCPUs
09:18:33 alex_xu stephenfin: okay, I thought people my blind to live migrate dedicated instance in case they have same hardware :)
09:18:51 alex_xu stephenfin: we don't have that option in the current version, right
09:19:22 alex_xu stephenfin: probably we can ask people live migration the instance before upgrade if they want
09:19:33 stephenfin No unless you explicitly set '[workarounds] enable_numa_live_migration'
09:19:36 stephenfin *Not
09:19:56 alex_xu oh, totally forget that option
09:20:17 stephenfin alex_xu: nah, if all they do is upgrade their compute nodes, nothing will change. They'll still be reporting and consuming VCPUs
09:20:55 openstackgerrit Gorka Eguileor proposed openstack/nova master: Use os-brick locking for volume attach and detach https://review.opendev.org/614190
09:20:57 stephenfin Things only change when the operator sets cpu_dedicated_set or cpu_shared_set on the controller, and set the as-yet-unnamed option on the controller
09:21:41 stephenfin when 'cpu_dedicated_set' is set, the compute node will start reporting PCPUs and transform existing inventory of pinned instances (if any) from VCPU to PCPU
09:21:50 alex_xu right
09:21:52 stephenfin not before that though
09:22:07 alex_xu stephenfin: so we still have that workaround option, in case people need it
09:23:31 stephenfin alex_xu: Yes, see https://review.opendev.org/#/c/671801/32/nova/conf/workarounds.py
09:23:42 stephenfin I'm going to have to rename and move that though, of course
09:24:35 bauzas stephenfin: you got hit by a merge conflict FWIW
09:24:36 bauzas https://review.opendev.org/#/c/671793/16
09:24:45 stephenfin yeah, I'll tackle that shortly
09:24:48 stephenfin expecting a lot of those
09:25:54 alex_xu stephenfin: ok, if the operator wants to upgrade the host os, then he can rolling upgrade the host os and nova-compute, without PCPU translating and cpu_dedicated_set. After all the nodes upgrade the new os and new nova-compute, then update the cpu_dedicated_set, to reshape the inventory, is that correct?
09:26:11 stephenfin yes
09:26:19 alex_xu so cool
09:26:44 alex_xu stephenfin: we really document those somewhere, like release note upgrade section?
09:27:28 stephenfin alex_xu: I've started here https://review.opendev.org/#/c/671793/16/releasenotes/notes/cpu-resources-d4e6a0c12681fa87.yaml
09:27:32 stephenfin But I'll add more as I go
09:27:38 bauzas alex_xu: yeah that's the plan
09:27:41 alex_xu stephenfin: cool
09:27:49 bauzas alex_xu: nothing changes unless the operator triggers it
09:28:07 alex_xu bauzas: yea, that is much simpler
09:28:08 bauzas but when they trigger, then it'll be a reshape
09:28:27 bauzas stephenfin: and that also implies we need to provide some nova-status check command
09:28:37 bauzas for upgrading to Unicorn
09:28:42 alex_xu stephenfin: also something fun https://review.opendev.org/#/c/674895/22/nova/virt/libvirt/driver.py, due to I updated a wrong option
09:29:18 sean-k-mooney alex_xu: dsid stephenfin answer your os upgrade question
09:29:31 alex_xu sean-k-mooney: yes, perfectly answered
09:30:59 gibi bauzas, stephenfin: hi! there are +2s from mriedem on the next couple patches in the support-move-ops-with-qos-ports series. starting here https://review.opendev.org/#/c/655110/
09:31:23 bauzas gibi: yeah, I was planning to put my eyes on your series after stephenfin's one
09:31:32 gibi bauzas: cool, thanks
09:44:39 yaawang stephenfin: alex_xu Hi, I had update the patches of vCPU models selection, can you take a look if you have time :) https://review.opendev.org/#/q/status:open+project:openstack/nova+branch:master+topic:bp/cpu-model-selection

11:11:09 stephenfin gibi: Yeah, that's on my list for today (t)

12:07:35 aspiers stephenfin: thanks for the reviews. BTW https://review.opendev.org/#/c/636334/ is missing W+1
12:08:14 aspiers stephenfin: I'm working on adding the checks you requested, for live migration / suspend etc.
12:21:03 kashyap aspiers: Nice, seems like the SEV work is almost merged.
12:21:14 aspiers kashyap: Yes, pretty close now :)
12:21:56 aspiers It's almost a year since I uploaded the Stein spec :-o
12:22:13 aspiers So this has been a year-long project or more already
12:23:19 kashyap It required a lot of 'supporting infra' work, which is also useful for other features (machine types rework; domCapabilities, etc)
12:23:28 aspiers Right
12:23:42 aspiers I'm glad it turned out to have other uses. Didn't anticipate that originally.
12:24:17 kashyap aspiers: Unrelated - SEV _requires_ 'q35', isn't it?
12:25:28 aspiers kashyap: http://eavesdrop.openstack.org/irclogs/%23openstack-nova/%23openstack-nova.2019-07-30.log.html#t2019-07-30T09:21:35
12:25:30 aspiers ;-)
