| gokhani | hi nova folks, I wonder if we can use gpu virtualization on ubuntu kvm compute nodes? In nvidia docs, I can't see support of ubuntu kvm hypervisor ( https://docs.nvidia.com/grid/7.0/product-support-matrix/index.html ). Is there any suggestions for gpu virtualization in an OpenStack environment which works on ubuntu 18.04? | 11:00 |
| sean-k-mooney | unless this is in unit tests | 11:00 |
| sean-k-mooney | even then you can set it via an env var | 11:01 |
| sean-k-mooney | gokhani: if you can install the driver then proably but they dont package for debian | 11:01 |
| *** yedongcan has quit IRC | 11:02 | |
| sean-k-mooney | if they are using dkms then you could proably use ailen too install the rpm | 11:02 |
| sean-k-mooney | not sure if it would work however | 11:02 |
| sean-k-mooney | gokhani: form a nova point of view we dont care | 11:03 |
| sean-k-mooney | nvida driver support is the limiting factor | 11:03 |

| gokhani | sean-k-mooney, I have a supermicro server which has 4 nvidia tesla v100-SXM2 gpu cards and nvidia has tesla driver for ubuntu 18.04 (https://www.nvidia.com/Download/driverResults.aspx/160638/en-us). but for virtual gpu software nvidia doesn't give debian package. may be I need to also consult nvidia. | 11:11 |
| sean-k-mooney | gokhani: you need a different driver for grid | 11:12 |
| sean-k-mooney | teslsa cards are supported on ubunut but i dont think grid is | 11:12 |
| sean-k-mooney | on the host at least for vgpu | 11:12 |
| *** ttsiouts has quit IRC | 11:12 | |
| sean-k-mooney | that does not mean you cant get it to work but yes you should contact nvidia | 11:13 |
| 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 | 11:13 |
| *** zhanglong has quit IRC | 11:14 | |
| *** ttsiouts has joined #openstack-nova | 11:17 | |
| 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. | 11:18 |
| sean-k-mooney | you cna use a low res gpu without cuda without a license i think | 11:19 |
| 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 | 11:20 |
| *** yedongcan has joined #openstack-nova | 11:21 | |
| gokhani | sorry what do you mean with *res ? | 11:22 |
| sean-k-mooney | resolution e.g i think its capped at 720p | 11:22 |
| 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 | 11:24 |
| sean-k-mooney | lyarwood: zuul should have cloned it | 11:25 |
| *** yedongcan has quit IRC | 11:25 | |
| sean-k-mooney | it does that before devstack-gate runs as far as i know | 11:25 |
| sean-k-mooney | so i think you can jsut pass -c /opt/git/openstack/requirements/upper-constriats.txt | 11:27 |
| lyarwood | hmmm I think this might actually be fixed, I can't reproduce locally | 11:28 |
| gokhani | sean-k-mooney, ok if I see correctly, for testing ı can test gpu virtualization with no license. | 11:28 |
| sean-k-mooney | gokhani: i belvie so just with reduced capablities | 11:30 |
| sean-k-mooney | bug you can confirm the hardware works | 11:30 |
| 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 ? | 11:35 |
| *** JamesBenson has joined #openstack-nova | 11:35 | |
| *** JamesBenson has quit IRC | 11:39 | |
| sean-k-mooney | gokhani: you need the vgpu software on your server | 11:41 |
| sean-k-mooney | nova just has the ablity to tell libvirt to configure it | 11:42 |
| sean-k-mooney | well vms that use vgpus | 11:42 |
| 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 | 11:43 |
| sean-k-mooney | gokhani: this should be all coverd in the nvida docs | 11:44 |

| isakgicu | Hi guys, is it possible to convert a file from /var/lib/nova/instances/_base to an image for glance ? | 13:41 |
| 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 ? | 13:44 |
| 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 | 13:46 |
| isakgicu | thank you for quick answer ! | 13:47 |
| isakgicu | gonna try | 13:47 |

| *** tonyb has joined #openstack-nova | 15:16 | |
| gmann | i remember we talked to disable g-api on subnode long back too but let's see in 738780 | 15:17 |
| lyarwood | yeah it eventually got nack'd as the glance team were using it during their grenade tests | 15:18 |

| *** mriedem has joined #openstack-nova | 15:18 | |
| 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/ | 15:18 |

| sean-k-mooney1 | elod: i think glance wanted to test multi store backends or soemthing like that | 15:19 |
| *** lifeless has joined #openstack-nova | 15:20 | |
| sean-k-mooney1 | elod: that is for zuulv3 jobs | 15:20 |
| sean-k-mooney1 | the legacy jobs still install it | 15:20 |
| lyarwood | https://review.opendev.org/#/q/312517d5101206b33d3c395d27ec93d385b7fd24 ah ha! | 15:21 |
| lyarwood | of course Ian has already fixed this | 15:21 |
| lyarwood | gmann: FWIW without this in stable/rocky all of the services are still using the pip installed uwsgi version | 15:22 |
| 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 | 15:24 |
| sean-k-mooney1 | gmann: its not strictly required fro multistore you can do that single node | 15:25 |
| sean-k-mooney1 | gmann: apparently it was actully for grenade | 15:25 |
| sean-k-mooney1 | not multistore | 15:26 |
| gmann | grenade? | 15:26 |
| *** sean-k-mooney1 is now known as sean-k-mooney | 15:26 | |
| sean-k-mooney | gmann: apparently glance were doing some testing in grenade that wanted to glance-api on the subnode | 15:27 |
| gmann | ohk | 15:27 |
| sean-k-mooney | but to be clear if the use the v3 grenade job they can contol that themselves | 15:27 |
| 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) | 15:27 |
| gmann | yeah and we have grenade zuulv3 till stable/train | 15:28 |
| lyarwood | elod: yeah posting that now | 15:28 |
| sean-k-mooney | well id devstack need to find the correct uwsgi to use we still might need to do the $(which...) | 15:28 |
| lyarwood | https://review.opendev.org/739072 | 15:28 |
| 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 | 15:29 |
| elod | lyarwood: thanks for the patch, looks good :] | 15:30 |

| stephenfin | We've got driver capabilities and those can optionally be reported as traits. Why would someone *not* want to report the trait? | 16:58 |
| 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? | 17:00 |
| melwitt | elod: yes, stephenfin fixed a bug in it in 1.4.0. we're very familiar with the bug downstream 😝 | 17:01 |
| melwitt | so I was thinking maybe we could opt into it by bumping upper-constraints for it on the stein branch | 17:02 |
| 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) | 17:02 |
| 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 |
| stephenfin | sean-k-mooney: melwitt: You're welcome 🌟 ;) | 17:03 |
| sean-k-mooney | elod: nope it was a proablem on py27 and several versions of py3 if i recall | 17:04 |
| 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 |
| melwitt | stephenfin: heh, gold star worthy indeed | 17:04 |
| elod | melwitt: and crossing fingers that it won't break other constraints ;) | 17:04 |
| 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 |
| sean-k-mooney | elod: stephenfin found a tricky race in how it processed the io streams | 17:05 |
| melwitt | elod: yeah... I'm not sure whether it will work out but I don't have any other ideas | 17:05 |
| stephenfin | elod: https://github.com/testing-cabal/subunit/pull/40 | 17:06 |
| elod | sean-k-mooney melwitt stephenfin : nice! thanks for the details, now the picture is somewhat complete :] | 17:07 |
| elod | i've added then the 'subunit raise to 1.4.0' to my TODOs :] | 17:08 |
