| 14:14:46 | tdemaret | Really, I don't understand, what I need to change : https://review.opendev.org/c/openstack/nova-specs/+/979696?tab=comments , really I think, I must change the mindset and read more spec file to understand the template and informations are mandatory. | |

| 15:13:21 | gibi | OK cpu_model_extra_flags = -tsa-sq-no, -tsa-l1-no | |
| 15:13:23 | gibi | solve sthat | |
| 15:13:28 | gibi | solves that | |
| 15:14:07 | gibi | aand reboot works from within the SNP guest now | |
| 15:15:37 | sean-k-mooney | oh cool | |
| 15:15:56 | gibi | updated the bug | |
| 15:16:03 | gibi | and dropping for the weekend | |
| 15:16:04 | gibi | o/ | |
| 15:16:04 | sean-k-mooney | have you tried cpu-mode=host-passthough | |
| 15:16:10 | gibi | it is with host-passthrough | |
| 15:16:19 | sean-k-mooney | ah thats a sperte bug so | |
| 15:16:24 | sean-k-mooney | gibi: enjoy the weekend | |
| 15:17:08 | gibi | thanks. same to you too | |

| 08:28:13 | Uggla | Hi gibi and bauzas, I will be on PTO for the next 3 weeks. Would you be able to run the upstream meeting on my behalf? | |
| 08:41:13 | bauzas | I can do it | |
| 08:41:36 | bauzas | maybe not on July 13th tho, I'll probably take the day off | |
| 08:41:45 | bauzas | but that's something we can discuss | |
| 08:45:02 | gibi | I can take July 13th if you take the others :) | |
| 08:45:35 | bauzas | heh, looks like we have a plan ;) | |
| 08:45:40 | gibi | OK | |
| 09:05:35 | Uggla | gibi, bauzas thanks I'll update the agenda accordingly. | |

| 11:58:22 | tkajinam | gibi, thanks a lot for reviews and tests ! | |
| 12:01:05 | gibi | tkajinam: thanks for the patches. I'm happy that we made a quick progress on SNP | |
| 12:01:42 | tkajinam | yeah :-D | |
| 12:02:20 | tkajinam | though it has been a long way for me, though, because SEV-SNP support has been the ultimate goal for me since I touched my initial work to support SEV-ES | |
| 12:03:08 | tkajinam | but finally we are close to complete that long journey, hopefully | |
| 12:20:00 | sean-k-mooney | tkajinam: we were talking about locked memory last week, i remembered at the weekend why we limited it to hugepages | |
| 12:20:12 | sean-k-mooney | tkajinam: locked memory cannot be swapped | |
| 12:20:27 | sean-k-mooney | tkajinam: so we limited it to hugepages becasuse hugepages cannot be overcommited | |
| 12:20:50 | sean-k-mooney | if you use locked memory with out hugepageas and you memory allocation ration is > 1.0 | |
| 12:20:56 | sean-k-mooney | then you will have OOM events | |
| 12:21:40 | sean-k-mooney | so while it can work for non hugepage memory i.e hw:mem_page_size=small we require you to enabel the numa aware memory trackign which disables oversubsction to use it to prevent OOM events | |
| 12:22:17 | sean-k-mooney | so it could work wiht annoumus memory but its not safe to use it that way unless you acount for it via ram allcoation ratio | |
| 12:22:28 | sean-k-mooney | that was why that limitation exits today | |
| 12:23:07 | sean-k-mooney | tkajinam: anyway that should not impact th sev-snp work just the background context the current design choice | |
| 12:40:57 | sean-k-mooney | gmaan: as an fyi i somethime see test_cold_migration_dest_compute_graceful_shutdown fila in the the functional/coverage tests | |
| 12:41:06 | sean-k-mooney | https://storage.bhs.cloud.ovh.net/v1/AUTH_dcaab5e32b234d56b626f72581e3644c/zuul_opendev_logs_dc2/openstack/dc227da7383b4f62ab0731d251d86e2f/testr_results.html | |
| 12:41:14 | sean-k-mooney | so that may be unstable in some caes | |
| 12:50:56 | opendevreview | sean mooney proposed openstack/nova master: Parallelize per-node resource updates https://review.opendev.org/c/openstack/nova/+/980679 | |
| 12:50:57 | opendevreview | sean mooney proposed openstack/nova master: docs: add Ironic startup performance measurements https://review.opendev.org/c/openstack/nova/+/980680 | |
| 12:50:57 | opendevreview | sean mooney proposed openstack/nova master: perf: add ironic startup performance simulator https://review.opendev.org/c/openstack/nova/+/980641 | |
| 13:08:34 | tkajinam | sean-k-mooney, ah ok. thanks for sharing that context. | |
| 14:03:37 | gibi | gmaan: bauzas: could one of take a look at this eventlet config patch https://review.opendev.org/c/openstack/nova/+/993760 this would be a helpful addition to our downstream performance testing efforts | |
| 14:05:53 | gibi | also, do you think it would make sense / possible to backport this to Gazpacho? (not super important as it seems downstream folks are building from master directly, so I'm just curious what you think): | |
| 14:15:47 | tkajinam | sean-k-mooney, I'm now reading your comment in https://review.opendev.org/c/openstack/nova/+/995835 ... I was thinking of rejecting usage of hw_firmware_stateles for bios boot because bios does support stateless/stateful concept and it's always stateless and am wondering what you think about it. | |
| 14:16:31 | sean-k-mooney | i dont thin that is a good idea | |
| 14:16:46 | sean-k-mooney | i think we shoudl only look at it if its uefi | |
| 14:17:04 | sean-k-mooney | becuase if anywon has set both today we dont want to break them when they upgrae | |
| 14:17:49 | sean-k-mooney | we have not been enforcing that restiction before correct? so enforcing it now would have an upgrade impact | |
| 14:18:17 | sean-k-mooney | if we had enforced it when we intoduced it it woudl have been fine | |
| 14:18:25 | sean-k-mooney | and perhaps correct | |
| 14:19:00 | sean-k-mooney | but unless we fix the existign instance on nova-compute startup that going to be problematic i think | |
