| 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 | |

| 10:39:49 | opendevreview | Ashish Gupta proposed openstack/nova master: tests: Use per-database write locks instead of global lock https://review.opendev.org/c/openstack/nova/+/992862 | |
| 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 | |
| 14:19:46 | sean-k-mooney | if we enfoce it now then if you have an image with bios and stateless configured to any value then resize will fail | |
| 14:20:08 | sean-k-mooney | and either an operator will need to fix it with nova-manage or you will need to rebuild | |
| 14:20:33 | sean-k-mooney | so the best i think we can do is log a warning | |
| 14:20:42 | tkajinam | that's correct, though the existing instance may have only bios boot with firmware_stateless=False which is incorrect | |
| 14:20:43 | tkajinam | ok | |
| 14:20:52 | tkajinam | I'll drop the validation and then add a warning message there | |
| 14:52:07 | opendevreview | Ashish Gupta proposed openstack/nova master: tests: file-backed SQLite with WAL in threading mode for Database and CellDatabases Fixtures https://review.opendev.org/c/openstack/nova/+/988583 | |
| 14:56:09 | opendevreview | Ashish Gupta proposed openstack/nova master: tests: use file-backed Placement SQLite in functional threading https://review.opendev.org/c/openstack/nova/+/992581 | |
| 14:58:18 | Uggla | Reminder: upstream meeting in ~ 1h | |
| 15:04:16 | opendevreview | Ashish Gupta proposed openstack/nova master: tests: Use per-database write locks instead of global lock https://review.opendev.org/c/openstack/nova/+/992862 | |
| 15:25:28 | opendevreview | Takashi Kajinami proposed openstack/nova master: Accept hw_firmware_stateless=True for BIOS firmware type https://review.opendev.org/c/openstack/nova/+/995835 | |
| 15:26:37 | mhen | tkajinam: I won't be able to attend today's meeting but I'll see if I can do some tinkering with my SEV-SNP node tomorrow regarding my comment in https://review.opendev.org/c/openstack/nova/+/994930 and report back | |
| 15:27:40 | tkajinam | mhen, thanks | |
| 15:28:20 | tkajinam | mhen, if libvirt isn't able to correct the correct rom firmware then I suspect something is still wrong in libvirt firmware detection or descriptor file | |
| 15:28:46 | tkajinam | the selection logic was updated to treat type: rom as stateless so stateless=true should trigger usage of type: rom (unless nothing else is selected) | |
| 15:29:32 | tkajinam | I suspect there is still a legacy descriptor file with sev-snp I have to check which firmware is actually selected and how its descriptor looks like | |
| 15:30:57 | opendevreview | Takashi Kajinami proposed openstack/nova master: compute: Validate SEV/SEV-ES support at start up https://review.opendev.org/c/openstack/nova/+/994342 | |
| 15:31:09 | opendevreview | Takashi Kajinami proposed openstack/nova master: libvirt: Ignore SEV-ES when SEV-SNP is detected https://review.opendev.org/c/openstack/nova/+/994343 | |
| 15:43:51 | opendevreview | Merged openstack/nova master: Return 400 for invalid properties for locked memory https://review.opendev.org/c/openstack/nova/+/995813 | |
