15:28:02 stephenfin bauzas: like oslo.confg?
15:28:11 bauzas in oslo.config yes
15:28:13 stephenfin I just assumed we'd regex it away
15:28:26 bauzas oh shit you're right
15:28:36 stephenfin i.e. something like (VGPU|CUSTOM_[A-Z_])
15:28:45 stephenfin but more complete
15:28:46 stephenfin :)
15:31:07 zigo bauzas: Hi there ! After a failed migration (mistake in the host ssh keys), I cannot start a GPU instance, it's telling me: "libvirt.libvirtError: internal error: Device 0000:41:00.0 is already in use"
15:31:10 zigo How can I fix this ?
15:31:22 zigo bauzas: I'm asking you because it's an instance with a GPU, as you can see...
15:31:45 bauzas zigo: sorrry, I need to go off
15:31:55 bauzas but looks like you already use the mdev
15:32:02 bauzas in another guest
15:32:06 zigo bauzas: No that's not the case.
15:32:15 zigo It's the only instance of this cloud with a GPU.
15:32:33 zigo (even though we have many available: one per compute)
15:33:11 zigo bauzas: Will you be able to help me later on?
15:33:23 zigo bauzas: It's an instance for Debconf, so it's a good cause ! :)
15:35:12 gibi zigo: bauzas is about to drop of for 3 weeks of PTO in -34 minutes. so your question came just in time :)
15:35:30 zigo Ah, shit ... :)
15:35:36 zigo I'll figure it out, no worries.
15:35:42 zigo bauzas: Have nice holidays !
15:35:51 bauzas and I need to work on stephenfin's concern
15:36:01 gibi zigo: so no other instance is using pci device 0000:41:00.0 on that host?
15:36:09 zigo gibi: Nop.
15:36:17 gibi still libvirt says it is used
15:36:22 stephenfin gibi: I've all but the nova-manage patch of the BW series reviewed. I assume that one can wait a while (it's in merge conflict). Also, melwitt is probably well placed to review that specifically
15:36:46 gibi stephenfin: thanks a lot. I'm still chewing on on your db series.
15:37:07 gibi stephenfin: sure the nova-manage part is the least important and it still misses some test coverage
15:37:34 gibi stephenfin: so you are out next week, will you be back still before the FF?
15:37:47 stephenfin nope, I'm here next week but I'm starting my move the new team
15:37:50 gibi zigo: have you tried to restart libvirtd ?
15:38:00 gibi stephenfin: ohh, then I mixed it
15:38:11 gibi stephenfin: I will be out next week :/
15:38:14 stephenfin I was supposed to be away but things came up
15:38:25 stephenfin I'll still be around for the rest of the cycle but in a reduced capacity
15:38:52 stephenfin so keep reviewing what I've already reviewed and rebasing my own patches, but no new work
15:38:56 gibi stephenfin: OK, I might corner you with some re-review for the packet rate series if needed and you wil see if you have time or not
15:39:05 stephenfin yup, sounds good :)
15:39:17 stephenfin there are two patches with TODOs left that I can see still
15:39:34 gibi zigo: it feels like it is some internal incosistency inside libvirtd
15:40:02 gibi stephenfin: yeah, the ones that needs the neutron counterpart to define the name of the extension
15:43:23 gibi stephenfin: the naming of api_db_api import made me chuckle :) that name well summarizes why naming is one of the hardest thing in programming
15:43:35 stephenfin Yeah :-(
15:43:49 gibi it is sooo historical
15:43:53 stephenfin I tried many alternatives and kept coming back to that
15:44:08 gibi it is not a fault of the current series at all
15:44:28 gibi the current series just distilled it to a well visible name
15:45:00 stephenfin I did considered removing the main DB's 'api' module and folding it in to nova.objects like we did for the API DB, but that was even more work in an already bloated series
15:45:01 stephenfin so...
15:46:13 gibi that api is huge so yeah
15:48:52 gibi it is impressive that you could push through this amount of refactoring in nova
15:54:12 opendevreview Sylvain Bauza proposed openstack/nova master: Provide the mdev class for every PCI device https://review.opendev.org/c/openstack/nova/+/802918
15:54:13 opendevreview Sylvain Bauza proposed openstack/nova master: Expose the mdev class https://review.opendev.org/c/openstack/nova/+/801743
15:54:13 opendevreview Sylvain Bauza proposed openstack/nova master: Provide and use other RCs for mdevs if needed https://review.opendev.org/c/openstack/nova/+/803233
15:54:14 opendevreview Sylvain Bauza proposed openstack/nova master: WIP: Cleanup GPU vs. mdev wording https://review.opendev.org/c/openstack/nova/+/803379
15:54:35 bauzas stephenfin: gibi: last round before I leave : change of the option value to be CUSTOM_ something
15:55:08 bauzas gibi: sorry if I may ask you to review just before you leave, but the changes are femtonits
15:55:20 bauzas I prevented to rebase
15:55:38 bauzas so, PS_n-2 to PS should show the very few differences
15:56:39 stephenfin bauzas: Thanks. I'll start looking now but I will have to leave myself soon enough
15:56:56 stephenfin Worst case scenario, one of us can tweak it while you're away to get it over the line
15:56:56 opendevreview Stephen Finucane proposed openstack/nova master: db: Exclude the 'use_db_reconnect' option https://review.opendev.org/c/openstack/nova/+/803778
15:57:11 stephenfin gibi: ^
15:57:50 stephenfin turns out I _could_ just modify what we were registering since I stopped registering the oslo.db opts in https://review.opendev.org/c/openstack/nova/+/799523/
15:58:02 bauzas stephenfin: I was planning to end at 5pm
15:58:15 bauzas looks like I was on the wrong timezone when I said this
15:58:42 stephenfin bauzas: it's still only 9am in California ;)
15:59:03 bauzas perfect timing for starting my day again
15:59:21 stephenfin bauzas: Can you bang this ~50 line change in as the last thing before you leave? :D https://review.opendev.org/c/openstack/nova/+/799523/
16:01:33 bauzas stephenfin: you eventually got my last approval before I leave, gibi you lose
16:01:42 stephenfin \o/
16:01:44 stephenfin winner winner
16:01:53 bauzas this is like the olympics, money time
16:02:00 stephenfin enjoy your PTO o.
16:02:22 bauzas stephenfin: be sure I'll haunt you when I'm back even if you're not lurking this chan
16:02:51 ade_lee stephenfin, lyarwood hey -- I started to look at the failures in the fips ci job -- https://review.opendev.org/c/openstack/nova/+/790519
16:03:49 ade_lee stephenfin, lyarwood looks like the bootfromvolume test is failing - and I think its because iscsid is not happy because its chap algorithm needs to be set to something other than md5
16:04:05 ade_lee not sure how to do that in the test ..
16:05:24 gibi bauzas_away: enjoy, I will look at your mdev series still today
16:05:25 stephenfin ade_lee: The test that's failing is an integration test running on devstack VM, so you're going to need to modify some configuration via devstack or a plugin
16:05:55 bauzas_away gibi: thanks, appreciated
16:06:14 bauzas_away anyway, back on tuesday means 2 days of work before FF, that's totally doable to merge things
16:06:34 ade_lee stephenfin, lyarwood in barbican, we do special test stuff on devstack with a script at https://github.com/openstack/barbican/blob/master/devstack/lib/barbican for instance , but I don't see anything similar in nova
16:06:48 gibi bauzas_away: :D you are such an optimist :D
16:07:04 ade_lee though as this is something that will likely show up elsewhere - its prob best to look in devstack itself ..
16:07:08 ade_lee looking ..
16:08:54 stephenfin ade_lee: this isn't stuff I'm intimately familiar with, but we do some stuff as a post-run job. For example, you can see the stuff in roles/run-evacuate-hook which is run as part of the nova-live-migration job
16:09:26 stephenfin pre-run probably won't do though since that'll surely run before DevStack even gets started, though maybe that's okay...
16:10:13 stephenfin doing it in DevStack (hidden behind a config option) or via a DevStack plugin would certainly be easier I suspect
16:11:38 ade_lee stephenfin, yeah and more useful as this will undoubtedly show up in cinder fips tests amongst others
16:11:44 stephenfin yup
16:38:28 gibi I'm dropping off for a week of vacation
16:38:33 gibi back on 16th of Aug
16:39:06 gibi_pto o/
16:39:24 stephenfin o/
16:39:25 opendevreview Stephen Finucane proposed openstack/nova master: mypy: Follow-up for I4a9c1ee486beda070ee0a4a9734a7ec9e2629a67 https://review.opendev.org/c/openstack/nova/+/803787
16:39:25 opendevreview Stephen Finucane proposed openstack/nova master: WIP: Expand type hints for nova.block_device https://review.opendev.org/c/openstack/nova/+/742170
16:57:06 opendevreview Merged openstack/nova master: db: Move main DB migrations https://review.opendev.org/c/openstack/nova/+/799519
17:31:44 gmann gibi_pto: have good vacation.
