| gthiemonge | Hi | 16:00 |
| johnsom | o/ | 16:00 |
| jdacunha4 | Hello | 16:01 |
| tweining_ | o/ | 16:01 |
| QG | o/ | 16:01 |

| gthiemonge | #topic Announcements | 16:02 |
| gthiemonge | No announcement from me... Does anyone have any announcements? | 16:02 |
| johnsom | Nope | 16:02 |
| gthiemonge | ack | 16:04 |
| gthiemonge | #topic CI Status | 16:04 |
| gthiemonge | we need a followup commit for the configuration of the CI jobs | 16:04 |
| gthiemonge | last week, I split the scenario jobs in 2 jobs in the check pipeline | 16:04 |
| gthiemonge | but I didn't update the gate pipeline :/ | 16:05 |
| gthiemonge | here is the new patch | 16:05 |
| gthiemonge | #link https://review.opendev.org/c/openstack/octavia/+/883999 | 16:05 |
| gthiemonge | as it unblocks the gate, it will be approved right after this meeting, unless someone raises concerns about it | 16:05 |
| gthiemonge | then I will squash this patch with https://review.opendev.org/c/openstack/octavia/+/883131 | 16:06 |
| gthiemonge | and propose backports to the stable branches that use Ubuntu Jammy | 16:06 |
| gthiemonge | FYI FIPS jobs are broken, it is not an octavia issue but a global issue | 16:07 |
| gthiemonge | there's a bug in the Octavia LP | 16:07 |
| gthiemonge | #link https://bugs.launchpad.net/octavia/+bug/2020434 | 16:07 |
| gthiemonge | I know that some folks are investigating it | 16:07 |
| gthiemonge | #topic Brief progress reports / bugs needing review | 16:09 |
| gthiemonge | I was on PTO, not much activity | 16:10 |
| jdacunha4 | I need some review/replies to the ACMEv2 implementation | 16:10 |
| jdacunha4 | here is the latest doc generated: https://426a74fa4eaec8e077a0-814491f7a8e968b50eeaf14b0c7f115f.ssl.cf5.rackcdn.com/877281/11/check/openstack-tox-docs/8486822/docs/contributor/specs/version1.1/letsencrypt.html | 16:10 |
| johnsom | I have made some progress with my SRIOV investigation. I was able to manually attach a VF to an amphora. | 16:11 |
| johnsom | Next step for me is putting together a spec for review | 16:11 |
| gthiemonge | jdacunha4: ack, I'm adding it to my todo list | 16:11 |
| jdacunha4 | some questions from johnsom are not replied, i need some more inputs/discussions | 16:11 |
| tweining_ | I am very interested in seeing that SRIOV spec. | 16:12 |
| jdacunha4 | #link https://review.opendev.org/c/openstack/octavia/+/877281 | 16:12 |
| jdacunha4 | thx | 16:13 |
| tweining_ | I got DPDK working with amps in my devstack environment without any code modification. It seems as long as the compute node is configured for DPDK nova will automatically configure the guest to use a vhost user mode port, which is nice. | 16:14 |
| gthiemonge | tweining_: do you know if the CPUs of the VMs are pinned automatically by Nova? | 16:16 |
| tweining_ | no, that is not Nova's job. | 16:17 |
| gthiemonge | (I mean on the compute node) | 16:17 |
| tweining_ | I did that manually using ovs-vsctl | 16:18 |
| tweining_ | it's the job of the deployment tool basically | 16:18 |
| QG | #link https://docs.openstack.org/nova/pike/admin/cpu-topologies.html | 16:19 |
| QG | you can pin, but it's not really praticle | 16:20 |
| gthiemonge | ok it's in the flavor | 16:20 |
| tweining_ | pinning cpus in the VM is unrelated to running DPDK on the compute node though | 16:21 |
| QG | like nova is not able to spread out between numa, it will first full fill the first one and then do the second one | 16:22 |
| QG | tweining_ yep | 16:22 |
| johnsom | Typically with DPDK you will want the hypervisor CPUs pinned for the VM too, not just processes inside the guest | 16:22 |
| tweining_ | mmh, ok. I didn't think about that yet. | 16:24 |
| gthiemonge | there's no rush ATM :) | 16:26 |
| tweining_ | anyway, I think there are quite a few patches that are waiting for review now | 16:30 |
| gthiemonge | +1 | 16:30 |
| gthiemonge | #topic Open Discussion | 16:30 |
| gthiemonge | any other topics, folks? | 16:31 |
| tweining_ | just for my understanding: do you expect Octavia to configure Nova to pin cpus for amp VMs? | 16:32 |
| gthiemonge | if we can do it with the flavor, we don't need to do anything else in Octavia | 16:33 |
| tweining_ | yeah, hugepages need to be enabled in the flavor (or image itself) anyway | 16:33 |
| gthiemonge | I think it is the "hw:cpu_policy=dedicated" property in QG's link | 16:33 |
| johnsom | Yeah, that is a common setting | 16:34 |
| johnsom | As also mentioned, NUMA can become an issue too. But we need to dance the line of not becoming a nova scheduler.... | 16:34 |
| tweining_ | ok, thanks. I think that's all from me | 16:36 |
| gthiemonge | ok, I think that's it for this meeting | 16:37 |
| gthiemonge | thank you guys! | 16:37 |
