| 16:24:18 | artom | An item for next PTG, perhaps | |
| 16:26:20 | priteau | Yeah that would be good | |
| 16:28:01 | priteau | I've proposed a spec for blazar to implement preemptibles, because in the context of using reservations it can be done without changes to nova | |
| 16:30:52 | priteau | That's the one linked by bauzas earlier: https://specs.openstack.org/openstack/blazar-specs/specs/ussuri/blazar-preemptible-instances.html | |
| 16:31:19 | artom | priteau, if that's the way it moves forward, RH would still have to productize Blazaar... | |
| 16:31:50 | artom | priteau, but good to know there would be no new code for us (RH) to write | |
| 16:31:53 | priteau | Yeah I am not saying this is a full solution for you ;) | |
| 16:32:11 | artom | Despite our millions, we're surprisingly people-strapped :P | |
| 16:32:30 | artom | Just getting Designate up and running was a more than year-long thing. | |

| 09:04:19 | slaweq | hi nova team | |
| 09:04:34 | slaweq | in one of neutron jobs I have errors in nova-compute, like https://df08b3f27c09a85d3fe8-f65209ceca8d59b8b2f1e727ebf5e4dd.ssl.cf2.rackcdn.com/periodic/opendev.org/openstack/neutron/master/devstack-tobiko-faults-centos/d402aac/compute1/logs/screen-n-cpu.txt | |
| 09:04:47 | slaweq | do You maybe know what can be the reason of such issue? | |
| 09:04:55 | slaweq | I have virt_type=qemu set there | |
| 09:05:01 | slaweq | and cpu_mode=None | |
| 09:31:00 | lyarwood | stephenfin: morning, if you get a chance today can you hit https://review.opendev.org/c/openstack/nova/+/794639 please? | |
| 09:31:40 | lyarwood | https://review.opendev.org/q/topic:%2522bug/1905701%2522+status:open+branch:master is also ready for review if anyone has time | |
| 10:00:57 | kashyap | gibi: Hey, today's the upstream call, yeah? I'd like to bring this (fairly mechanical thing) up today - https://blueprints.launchpad.net/nova/+spec/add-bochs-display-device | |
| 10:02:06 | kashyap | gibi: WIP here: https://review.opendev.org/q/topic:%22bp%252Fadd-bochs-display-device%22+(status:open%20OR%20status:merged) | |
| 10:27:45 | sean-k-mooney | slaweq: it looks like that job is trying to enable sev es to be availe in the guest without kvm | |
| 10:28:10 | sean-k-mooney | libvirt.libvirtError: internal error: unknown feature amd-sev-es | |
| 10:29:07 | slaweq | sean-k-mooney yeah, but there is nothing like that configured in the job | |
| 10:29:18 | slaweq | and that's actually weird for me :) | |
| 10:29:57 | slaweq | sean-k-mooney I think we may be hitting https://bugzilla.redhat.com/show_bug.cgi?id=1961562 there | |
| 10:29:58 | opendevmeet | bugzilla.redhat.com bug 1961562 in libvirt "vm can not start with error as "internal error: unknown feature amd-sev-es"" [Urgent,Verified] - Assigned to phrdina | |
| 10:30:14 | sean-k-mooney | slaweq: ya its not a nova bug | |
| 10:30:21 | slaweq | but would be great if You could confirm that :) | |
| 10:30:37 | sean-k-mooney | we are not requesting it in the xml so this a libvirt /qemu issue on the amd host | |
| 10:31:01 | sean-k-mooney | ah ok | |
| 10:32:53 | sean-k-mooney | so that looks like the exact same issue | |
| 10:32:55 | sean-k-mooney | Error from libvirt when retrieving domain capabilities for arch i686 / virt_type qemu / machine_type q35: [Error Code 1]: internal error: unknown feature amd-sev-es {{(pid=75619) _add_to_domain_capabilities /opt/stack/nova/nova/virt/libvirt/host.py:982}} | |
| 10:33:40 | sean-k-mooney | slaweq: as a workaround you could likely define a cpu model that did not support sev-es | |
| 10:34:22 | slaweq | sean-k-mooney thx, I will try that | |
| 10:35:03 | sean-k-mooney | cpu_mode=custom cpu_model=EPYC-IBPB | |
| 10:35:12 | sean-k-mooney | in the libvirt section | |
| 10:35:48 | sean-k-mooney | cpu_mode=none in the libvirt driver on x86 is equvalent to cpu_mode=host-model | |
| 10:36:52 | sean-k-mooney | although it is actully generating <cpu match="exact"> with qemu instead of kvm | |
| 10:37:15 | sean-k-mooney | which i tought was the same as host-passthough not host-model since there is no model specified | |
| 10:37:53 | slaweq | ok, so setting cpu_mode=custom cpu_model=EPYC-IBPB in the job should helps to workaround that issue, correct? | |
| 10:41:05 | sean-k-mooney | yes i think so but only if we know that all the host support that | |
| 10:41:18 | sean-k-mooney | if we dont know that we have other options | |
| 10:42:29 | sean-k-mooney | we could go with cpu_model=kvm64 or proably Nehalem-IBRS | |
| 10:43:07 | slaweq | sean-k-mooney that job is running in the u/s ci so I can't be sure that all providers will support that EPYC-IBPB | |
| 10:43:10 | sean-k-mooney | cpu_model=Nehalem-IBRS while an intel plathform is very clouse to the new x86 featrel level that is being used to compile rhel 9 with | |
| 10:44:09 | slaweq | and also tests in that job don't need any advanced cpu features so I think that I would try with as much "generic" type as possible | |
| 10:44:11 | sean-k-mooney | slaweq: i would try cpu_model=Nehalem-IBRS then and if that dows not work try falling back to qemu64 | |
| 10:44:29 | slaweq | sean-k-mooney ok, thx a lot | |
| 10:44:32 | slaweq | I will try that | |
| 10:44:46 | kashyap | slaweq: The EPYC-IBPB model will only work if ... obviously your host supports it | |
| 10:44:56 | kashyap | You can check it via `virsh cpu-models x86_64` | |
| 10:45:21 | kashyap | ("it" == supported models by your libvirt+QEMU) | |
| 10:45:47 | slaweq | kashyap I actually can't check it like that in the zuul ci jobs | |
| 10:45:47 | sean-k-mooney | kashyap: this is running on upshift which is hosted by vexhost using i would guess there new amd eypc zen2 servers | |
| 10:47:29 | sean-k-mooney | assuming they are all the same then they are second gen epyc cpus from 2 years ago but nehalem is ~8-11 years old so it should be emulatable on anything that is still in production today | |
| 10:47:43 | kashyap | I see | |
| 10:53:50 | stephenfin | lyarwood: took me a bit but +2 on https://review.opendev.org/c/openstack/nova/+/794639 now. sean-k-mooney might be interested if they've time | |
| 10:55:47 | sean-k-mooney | i can re review it now | |
| 10:56:50 | stephenfin | lyarwood: also, can you send an email to openstack-discuss RE: https://review.opendev.org/c/openstack/nova/+/794252. They're likely totally useless but we've always done it historically | |
| 10:57:04 | sean-k-mooney | stephenfin: well | |
| 10:57:12 | sean-k-mooney | for PCI passthrough attach, from '_attach_direct_passthrough_ports': not relevant since these clearly can't be virtio devices | |
| 10:57:17 | sean-k-mooney | they can | |
| 10:57:28 | sean-k-mooney | oh _attach_direct_passthrough_ports | |
| 10:57:50 | stephenfin | Really? That doesn't make much sense to me | |
| 10:57:58 | sean-k-mooney | i was going to say macvtap and vdpa sriov interface will be virtio | |
| 10:58:03 | stephenfin | Other types of "passthrough", sure | |
| 10:58:04 | stephenfin | Yeah | |
| 10:58:18 | sean-k-mooney | if that is just direct then ya | |
| 10:58:46 | stephenfin | Would be good to double check. I think it is but I might have missed something | |
| 10:59:27 | sean-k-mooney | im checking now but it shoudl be fine | |
| 10:59:45 | stephenfin | in other news, /me has a briar thorn stuck in his fingertip that he can't remove which is making typing extremely uncomfortable today :-D | |
| 10:59:53 | sean-k-mooney | attach_interface is the entrypoint that would handel all sriov attach anyway | |
| 11:00:14 | sean-k-mooney | ouch | |
| 11:01:13 | sean-k-mooney | stephenfin: so right now it should be ok https://github.com/openstack/nova/blob/master/nova/virt/libvirt/driver.py#L4821-L4840 | |
| 11:01:43 | sean-k-mooney | i have worked with prototype nics that expsoed virtio-net-pci devices as VFsd though in the past | |
| 11:08:23 | sean-k-mooney | with the caveat the i woudl silll like the sev atibetes fo the nices to be handeled in vif.py eventualy im +1 on that change | |
| 11:13:08 | opendevreview | Stephen Finucane proposed openstack/nova master: docs: Replace 'nova boot' with 'openstack server create' https://review.opendev.org/c/openstack/nova/+/794007 | |
| 11:13:14 | gibi | kashyap: ack, I've added to the agenda | |
| 11:13:59 | stephenfin | gibi: lyarwood: if you've time this week, could I get your eyes on this follow-up series for the RPC 6.0 change from last cycle. bauzas is +2 on pretty much all of it now https://review.opendev.org/q/topic:"compute_rpc_6.0"+status:open | |
| 11:20:13 | sean-k-mooney | stephenfin: is that removing the proxy? | |
