| 11:12:45 | sean-k-mooney | teslsa cards are supported on ubunut but i dont think grid is | |
| 11:12:52 | sean-k-mooney | on the host at least for vgpu | |
| 11:13:11 | sean-k-mooney | that does not mean you cant get it to work but yes you should contact nvidia | |
| 11:13:49 | sean-k-mooney | you will also need to buy the approriate licenses and set up the server to delegate the licneses to your compute nodes | |
| 11:18:22 | gokhani | sean-k-mooney, ok ı see. initially I wanna test vgpu on openstack and then if everything goes well, we are planning to buy appropriate licenses. If I can't get it to work on ubuntu, I will try centos/rhel. | |
| 11:19:23 | sean-k-mooney | you cna use a low res gpu without cuda without a license i think | |
| 11:20:10 | sean-k-mooney | so you can test you can boot a vm but not use if for useful work beyond a slighly better vnc/spice console experinece | |
| 11:22:09 | gokhani | sorry what do you mean with *res ? | |
| 11:22:32 | sean-k-mooney | resolution e.g i think its capped at 720p | |
| 11:24:47 | lyarwood | sean-k-mooney: sorry back, https://github.com/openstack/devstack-gate/blob/master/devstack-vm-gate-wrap.sh#L519-L520 is the issue, I don't think we actually have requirements pulled down for the correct branch at this point | |
| 11:25:11 | sean-k-mooney | lyarwood: zuul should have cloned it | |
| 11:25:33 | sean-k-mooney | it does that before devstack-gate runs as far as i know | |
| 11:27:47 | sean-k-mooney | so i think you can jsut pass -c /opt/git/openstack/requirements/upper-constriats.txt | |
| 11:28:07 | lyarwood | hmmm I think this might actually be fixed, I can't reproduce locally | |
| 11:28:23 | gokhani | sean-k-mooney, ok if I see correctly, for testing ı can test gpu virtualization with no license. | |
| 11:30:20 | sean-k-mooney | gokhani: i belvie so just with reduced capablities | |
| 11:30:27 | sean-k-mooney | bug you can confirm the hardware works | |
| 11:35:01 | gokhani | sean-k-mooney, I am confused. from nova point for using nvidia vgpu capabilities, do I need also nvidia vgpu software on my server or it is built in function in nova ? ı mean tesla or grid driver is enough for nova except licenses ? | |
| 11:41:50 | sean-k-mooney | gokhani: you need the vgpu software on your server | |
| 11:42:05 | sean-k-mooney | nova just has the ablity to tell libvirt to configure it | |
| 11:42:13 | sean-k-mooney | well vms that use vgpus | |
| 11:43:58 | sean-k-mooney | gokhani: the lices are ativly issued by a server like windows linces so you need to run an instance of that licensing serverr somewhere and you need to configre the hosts to phone home ot that server everytime a vms is booted with a vgpu to claim a lisence | |
| 11:44:18 | sean-k-mooney | gokhani: this should be all coverd in the nvida docs | |
| 11:44:31 | sean-k-mooney | its not specific to nova | |
| 11:57:05 | gibi | stephenfin: left a bunch of notes in https://review.opendev.org/#/c/631363 . I can be convinced to do the functional test coverage in a follow up | |

| 12:13:10 | jsuchome | gibi: Hi, I've created https://review.opendev.org/#/c/738738/ for you | |
| 12:13:45 | gibi | jsuchome: thans! | |
| 12:13:47 | gibi | thanks | |
| 12:17:11 | gokhani | sean-k-mooney, thanks for your useful information. After consulting to nvidia, I will decide. | |

| 12:56:58 | stephenfin | dansmith: Can you look at https://review.opendev.org/#/c/683043/ again today? | |
| 13:16:44 | openstackgerrit | Lee Yarwood proposed openstack/nova stable/rocky: Make greande jobs n-v for EM and oldest stable https://review.opendev.org/739020 | |
| 13:35:39 | openstackgerrit | Lee Yarwood proposed openstack/nova stable/rocky: fix scsi disk unit number of the attaching volume when cdrom bus is scsi https://review.opendev.org/730312 | |
| 13:41:39 | isakgicu | Hi guys, is it possible to convert a file from /var/lib/nova/instances/_base to an image for glance ? | |
| 13:44:59 | isakgicu | for example, accidentally an image from glance was deleted after instances where created, but I know which file from /var/lib/nova/instances/_base/ is an actual copy of that image, is it possible to make an image from /var/lib/nova/instances/_base/ files ? | |
| 13:46:15 | lyarwood | isakgicu: yeah assuming it's just a RAW file you should be able to copy it and upload it as a fresh image into glance | |
| 13:47:20 | isakgicu | thank you for quick answer ! | |
| 13:47:24 | isakgicu | gonna try | |
| 15:04:51 | gmann | lyarwood: np! now we have devstack is up for stable/rocky - https://review.opendev.org/#/c/735615/9 | |
| 15:05:13 | gmann | lyarwood: we should be good to do for nova now, grenade jobs as n-v | |
| 15:12:30 | lyarwood | gmann: ack yeah thanks, we are seeing an issue with g-api on the subnodes being unable to run as uwsgi is installed under a different path on 16.04 | |
| 15:12:46 | lyarwood | just working through it now | |
| 15:16:26 | gmann | lyarwood: yeah, we actually do not run uwsgi on subnode as no api service is supposed to run there - https://review.opendev.org/#/c/738780/ | |
| 15:17:16 | gmann | i remember we talked to disable g-api on subnode long back too but let's see in 738780 | |
| 15:18:11 | lyarwood | yeah it eventually got nack'd as the glance team were using it during their grenade tests | |
| 15:18:19 | lyarwood | https://review.opendev.org/#/q/I02bff11495f29822f1b5d0123d26df7c9bb76b30 | |
| 15:18:55 | elod | gmann lyarwood : actually I'm surprised that g-api is installed on subnode, because this patch removed it (at least I thought that): https://review.opendev.org/#/c/546765/ | |
| 15:19:33 | sean-k-mooney1 | elod: i think glance wanted to test multi store backends or soemthing like that | |
| 15:20:27 | sean-k-mooney1 | elod: that is for zuulv3 jobs | |
| 15:20:36 | sean-k-mooney1 | the legacy jobs still install it | |
| 15:21:02 | lyarwood | https://review.opendev.org/#/q/312517d5101206b33d3c395d27ec93d385b7fd24 ah ha! | |
| 15:21:08 | lyarwood | of course Ian has already fixed this | |
| 15:22:30 | lyarwood | gmann: FWIW without this in stable/rocky all of the services are still using the pip installed uwsgi version | |
| 15:24:58 | gmann | elod: sean-k-mooney1 lyarwood if it needed in mutlistore then we also need uwsgi setup in subnode too but that can be from Victoria and all stable can remove g-api may be | |
| 15:25:28 | sean-k-mooney1 | gmann: its not strictly required fro multistore you can do that single node | |
| 15:25:57 | sean-k-mooney1 | gmann: apparently it was actully for grenade | |
| 15:26:05 | sean-k-mooney1 | not multistore | |
| 15:26:16 | gmann | grenade? | |
| 15:27:16 | sean-k-mooney | gmann: apparently glance were doing some testing in grenade that wanted to glance-api on the subnode | |
| 15:27:31 | gmann | ohk | |
| 15:27:42 | sean-k-mooney | but to be clear if the use the v3 grenade job they can contol that themselves | |
| 15:27:45 | elod | i found it on multinode only, but if glance team needs g-api on subnode, then maybe the easiest fix is just to use '$(which uwsgi)' in glance (and others) | |
| 15:28:08 | gmann | yeah and we have grenade zuulv3 till stable/train | |
| 15:28:53 | lyarwood | elod: yeah posting that now | |
| 15:28:56 | sean-k-mooney | well id devstack need to find the correct uwsgi to use we still might need to do the $(which...) | |
| 15:28:58 | lyarwood | https://review.opendev.org/739072 | |
| 15:29:17 | sean-k-mooney | but they can at least contol if its enabled on the subnode trivially so we can disable it by defualt if we want too | |
| 15:30:42 | elod | lyarwood: thanks for the patch, looks good :] | |
| 15:30:50 | openstackgerrit | Lee Yarwood proposed openstack/nova stable/rocky: DNM - Testing g-api on subnode fix https://review.opendev.org/739074 | |
| 15:30:52 | lyarwood | ^ testing there | |
| 15:35:13 | gmann | lyarwood: thanks | |
| 15:40:45 | openstackgerrit | Lucio Seki proposed openstack/nova master: Implement extend_volume for libvirt NFS volume driver https://review.opendev.org/739077 | |
| 15:56:58 | gibi | nova meeting starts in 3 minutes on #openstack-meeting-3 | |
| 16:58:51 | stephenfin | We've got driver capabilities and those can optionally be reported as traits. Why would someone *not* want to report the trait? | |
| 17:00:39 | elod | melwitt: about subunit.parser: i've seen that only on stein (so far). do you think subunit 1.4.0 would make that dissappear? | |
| 17:01:35 | melwitt | elod: yes, stephenfin fixed a bug in it in 1.4.0. we're very familiar with the bug downstream 😝 | |
| 17:02:15 | melwitt | so I was thinking maybe we could opt into it by bumping upper-constraints for it on the stein branch | |
| 17:02:58 | elod | melwitt: oh, i see. then I will try to see if that is possible to raise it to 1.4.0 in Stein (if i'm not mistaken it's only a problem with py35) | |
| 17:03:18 | sean-k-mooney | we are pretty familar with it upstram too considering how much pain it has caused around Feature Freaze for thae last few cycles | |
| 17:03:50 | stephenfin | sean-k-mooney: melwitt: You're welcome 🌟 ;) | |
| 17:04:01 | sean-k-mooney | elod: nope it was a proablem on py27 and several versions of py3 if i recall | |
| 17:04:02 | melwitt | elod: yeah I was thinking we could propose it to openstack/requirements upper-constraints. we can't bump lower bounds on stable but we can bump upper bounds | |
| 17:04:21 | melwitt | stephenfin: heh, gold star worthy indeed | |
| 17:04:49 | elod | melwitt: and crossing fingers that it won't break other constraints ;) | |
| 17:05:01 | sean-k-mooney | elod: basically the subunit parser bug can happen anytime the output of the test exceed the size of a single frame in the subunit protocol | |
| 17:05:50 | sean-k-mooney | elod: stephenfin found a tricky race in how it processed the io streams | |
| 17:05:52 | melwitt | elod: yeah... I'm not sure whether it will work out but I don't have any other ideas | |
| 17:06:11 | stephenfin | elod: https://github.com/testing-cabal/subunit/pull/40 | |
| 17:07:22 | elod | sean-k-mooney melwitt stephenfin : nice! thanks for the details, now the picture is somewhat complete :] | |
| 17:08:13 | elod | i've added then the 'subunit raise to 1.4.0' to my TODOs :] | |
