17:22:01 sean-k-mooney colby__: so you should not be passing --shared-srotage wehn live migrating
17:22:32 colby__ I was just using the GUI for the live migration but can switch to the cli
17:22:36 sean-k-mooney you should be using a newer microvstion where that defautl to auto
17:23:10 sean-k-mooney so for boot form volume guest you should not tick shared storage
17:23:43 sean-k-mooney shared storage for that option really means is /var/lib/nova on nfs
17:23:58 sean-k-mooney so are you using images_type=rbd
17:24:17 colby__ no
17:24:23 colby__ just set to default
17:24:30 sean-k-mooney i missed typed
17:25:11 sean-k-mooney what i ment is you only say "shared_stroage=true" if you the vm is booted on a shared file cycle without using cinder volumes
17:25:21 sean-k-mooney so that is not your case
17:25:35 colby__ also there is no check box for shared storage just "block migration" and "disk overcommit" on gui live migration
17:25:56 sean-k-mooney right so your using horizon yes?
17:26:22 sean-k-mooney it likely would be better to do live migration form the openstack client
17:26:32 colby__ yep will try that
17:28:38 sean-k-mooney so in mitaka 2.25 we added auto
17:28:40 sean-k-mooney https://docs.openstack.org/nova/latest/reference/api-microversion-history.html#maximum-in-mitaka
17:32:14 melwitt stephenfin: I wondered if you might be able to shed some light on this bug report regarding an alembic migration https://bugs.launchpad.net/nova/+bug/2008716 they report a failure to drop columns in the build_requests table going from xena -> yoga. yet this doesn't fail in the grenade job for xena -> yoga, so I'm confused if there is really a bug?
17:40:35 sean-k-mooney melwitt: i think gibi ^ looked at that before
17:40:38 colby__ sean-k-mooney: that seemed to work. Im able to migrate from xena to yoga hypervisor. But Im not able to migrate to the original hypervisor that I fully patched (updated qemu/libvirt). On that machine Im seeing the following: qemu-kvm: load of migration failed: Invalid argument: libvirt.libvirtError: internal error: qemu unexpectedly closed the monitor: 2023-10-18T17:33:57.637682Z qemu-kvm: Missing section footer for
17:41:22 sean-k-mooney i that sound liek a qemu crash
17:44:54 melwitt sean-k-mooney: yeah, he did and I agree it seems like a bug in the migration. but if it is, why doesn't it fail in grenade? I looked for awhile and couldn't figure it out. I thought stephenfin might have ideas since he worked on alembic stuff
17:46:21 sean-k-mooney i think we get diffent behavior in fressh install vs upgraded case but i dont exactly rememebr why
17:46:54 sean-k-mooney i assume the base scemea we use in once ase either has or does not have the column
17:48:23 melwitt yeah.. if a fresh install of xena doesn't have the columns and the yoga migration would fail to drop them bc they don't exist, I thought it should have happened in grenade since grenade does a fresh install of xena and then upgrades it to yoga
17:48:34 sean-k-mooney https://github.com/openstack/nova/blob/stable/xena/nova/db/api/migrations/versions/d67eeaabee36_initial_version.py#L175-L208
17:48:46 sean-k-mooney so that is how the build request tabel is created on a clena install
17:49:21 sean-k-mooney https://github.com/openstack/nova/blob/stable/xena/nova/db/api/migrations/versions/d67eeaabee36_initial_version.py#L186
17:49:28 sean-k-mooney so it has vm_states
17:49:36 sean-k-mooney so a clean install on xena woudl have it
17:49:54 sean-k-mooney but a cloud that was upgraded form wallaby perhaps might not
17:50:49 sean-k-mooney hum it should be there in wallaby https://github.com/openstack/nova/blob/stable/wallaby/nova/db/sqlalchemy/api_migrations/migrate_repo/versions/067_train.py#L178
17:51:33 melwitt older versions do the initial migration too. I am just not seeing how it's possible to get into a case where you don't have the columns in xena if the yoga migration is the only thing that removes them
17:51:46 sean-k-mooney its also there if you use legacy migrations for green filed in xena https://github.com/openstack/nova/blob/stable/xena/nova/db/api/legacy_migrations/versions/067_train.py#L166
17:52:14 sean-k-mooney melwitt: perhaps we need to look at the code before we collapsed the migrations
17:54:26 sean-k-mooney if the bug was intoduced anywhere it was in the db compaction series
17:57:10 sean-k-mooney so in the patch before the dbcompaction
17:57:12 sean-k-mooney https://github.com/openstack/nova/blob/2d4eff0ef789957fe5498640015a6cccff43a2c3/nova/db/sqlalchemy/api_models.py#L241
17:57:27 sean-k-mooney the build request tabel did not have the offending colum in the model
17:59:11 sean-k-mooney ah hwere so even then it was created in migration 6 with the field
17:59:13 sean-k-mooney https://github.com/openstack/nova/blob/2d4eff0ef789957fe5498640015a6cccff43a2c3/nova/db/sqlalchemy/api_migrations/migrate_repo/versions/006_build_request.py#L48
18:00:21 sean-k-mooney i dont see the removal migation however at this point in the repo
18:01:31 melwitt is that yoga? bc the removal migration was added in yoga I think
18:01:46 sean-k-mooney that is xena
18:01:58 melwitt oh ok
18:02:00 sean-k-mooney so in xena the table was created with the column and i dont see the removal
18:02:15 sean-k-mooney an pre xena the colume also existed
18:03:19 sean-k-mooney do you knwo which commit added the drop
18:04:17 sean-k-mooney https://github.com/openstack/nova/commit/9657297dd6c63e7a1e0c84c3e943b26f1795d388
18:06:07 sean-k-mooney so honestly i don tsee the bug
18:06:35 sean-k-mooney xena had the colume and both ways of createating a clena db have the column
18:32:50 melwitt yeah, same

14:12:12 dansmith sean-k-mooney: can you hit this? https://review.opendev.org/c/openstack/nova/+/898741
14:17:41 sean-k-mooney sorry was doing something else but sure i can look at it now
14:17:52 sean-k-mooney ah the revert sure
14:18:18 sean-k-mooney done
14:18:47 dansmith sean-k-mooney: yeah didn't mean to distract, just figured it was an easy +W
14:19:20 sean-k-mooney no its fine i was just commiting something had litrally just finished
14:20:11 sean-k-mooney so before i started somethign else is the perfect time to ping
14:54:21 bauzas guys, I have a conflicting personal appointment next Friday at 4pm UTC
14:54:28 bauzas next Thur*
14:54:51 bauzas do people prefer we unbook the slot or do we leave it without me ?
14:56:21 dansmith I think we can do things without you, but maybe try to avoid scheduling anything important there and we can use it as open discussion if and as appropriate?
14:56:35 bauzas cool, I just noted it then in the etherpad
14:58:02 bauzas ralonsoh: do you have any nova related topics you'd like to be discussed at the PTG ?
14:58:46 ralonsoh bauzas, hi, I won't be able to attend next week to the PTG. The PTL is haleyb. I'm not aware of any Nova-Neutron topic for this PTG
14:59:09 bauzas ack, good call actually, I missed the PTL change, my bad
14:59:33 bauzas haleyb: cool cool, I was just asking
14:59:34 haleyb bauzas: i'm happy to have a cross-project
14:59:55 haleyb if needed of course
15:00:07 bauzas haleyb: for the moment, I haven't seen any related topics in our own etherpad but that's something we can quickly sort out
15:00:56 haleyb +1
15:30:59 bauzas carloss: same question for Manila, would you like some x-p session with nova ? I don't have any specific item in our etherpad as of now, but I'm open
15:37:20 carloss bauzas: o/ thought about it but unsure if we'd have a lot to cover in the session... we merged the two Manila features last cycle, so we are waiting on the Nova side implementation mostly to gather feedback and work on enhancements if necessary
15:37:42 bauzas carloss: yeah basically I think you're done :)
15:37:47 bauzas this is more on our side
15:38:02 bauzas but you may want to ask us some things that aren't discussed yet :)

06:54:26 bauzas hmmm, just got some moderator info, would people be angry against me if this time we use OpenDev Meetpad instead of Zoom for the PTG ? :)
06:59:03 frickler bauzas: interesting things happening behind closed doors again it seems. could you forward me that moderator mail or is there something confidential in it?
06:59:31 bauzas frickler: sure, no creds given
06:59:32 frickler fwiw I'm +2 on using meetpad. oh, wait, I only have +1 here, but anyway ;)
06:59:59 bauzas frickler: I guess I can fwd it to your gerrit email address ?
07:00:11 frickler bauzas: yes, please, tia
07:00:48 bauzas actually the email contains the host keys for the zoom sessions but I trust you hombre :)
07:01:04 bauzas you're not a scammer wanting to sell pills ?
07:01:25 frickler who knows. but if you don't use zoom, you won't get any ;-P
07:01:52 bauzas I'm half-sad, half-relieved
07:02:21 bauzas sent anyway
07:02:58 bauzas tl;dr: no really juice, that's just that it seems the OIF doesn't appreciate the new Zoom policies
07:03:12 bauzas "Due to Zoom’s more recent changes in policies we do encourage the use of the OpenDev Meetpad instance[3] instead and will work towards updating the bot for future vPTGs to make it the default meeting platform.  "
