| 19:54:21 | clif | I'm trying to run py3 tox target locally on latest master but I'm getting a lot (217) failed unit tests. Is there something I'm supposed to do besides git clone and then tox -epy3? | |
| 19:54:38 | clif | I've made sure I have a completely clean tree | |
| 19:55:02 | clif | One message I'm seeing a lot of in failures: "Exception: This test invokes builtins.open on /sys/module/kvm_amd/parameters/sev. It is bad, you should mock it." | |
| 20:22:46 | dansmith | clif: are you on something other than linux? although from the look of that, I'd guess maybe even being on linux but without SEV support you might hit that | |
| 20:22:50 | dansmith | I'd think the latter would affect CI though | |
| 20:23:36 | clif | linux, fedora specifically | |
| 20:24:33 | dansmith | ack, should work of course.. maybe hit tkajinam knows if something merged recently for the CC stuff that might be related | |
| 20:25:33 | clif | Is there a way to turn off or skip sev specific tests? I'm not familiar with the feature, I *am* running an AMD cpu | |
| 20:25:57 | clif | but a desktop chip, not EPYC | |
| 20:28:06 | JayF | I don't know if practices in Nova are different, but we'd also generally treat a non-mocked read of stuff outta /sys (or proc, or dev, or anything-local) in unit tests as a bug | |
| 20:28:10 | JayF | (in Ironic) | |
| 20:37:10 | dansmith | yep for sure, hence why I'm suggesting it might be a recent merge and the CC people might know of something obvious | |
| 23:20:58 | tkajinam | clif, which commit hash are you using ? | |
| 23:27:09 | clif | 39dc667a1f9a7c12814f5892b900462560b1a229 as of last attemp | |

| 08:36:44 | gibi | bauzas: could you look back at you gpu doc patch we have some question there https://review.opendev.org/c/openstack/nova/+/999607 | |
| 08:37:52 | bauzas | gibi: you're making a great point, this is not only for vfio-mdev but also for vfio-pci variant driver migrations | |
| 08:38:33 | bauzas | I'll amend the doc patch to mention vfio-pci too | |
| 09:19:31 | opendevreview | Sylvain Bauza proposed openstack/nova master: doc: Document postcopy incompatibility with vGPU live migration https://review.opendev.org/c/openstack/nova/+/999607 | |
| 09:45:16 | sean-k-mooney | bauzas: you or cursor added "Co-authored-by: Cursor <cursoragent@cursor.com>" that wrong, but otherwise the commit looks fine to me | |
| 09:45:27 | bauzas | doh | |
| 09:45:35 | bauzas | I'll change that | |
| 09:46:28 | opendevreview | Sylvain Bauza proposed openstack/nova master: doc: Document postcopy incompatibility with vGPU live migration https://review.opendev.org/c/openstack/nova/+/999607 | |
| 09:46:46 | sean-k-mooney | thanks | |
| 09:48:35 | sean-k-mooney | bauzas: speaking of gpus i have some cyborg related gpu patches that i would like to progress on the nova side. | |
| 09:49:09 | sean-k-mooney | if i can find them again :) | |
| 09:49:36 | sean-k-mooney | ah yes https://review.opendev.org/q/topic:%22bp/support-vfio-variant-driver-managed-mode-via-cyborg%22 | |
| 09:49:52 | bauzas | no promises I can review them but I'll try | |
| 09:49:55 | sean-k-mooney | im going to be rebasing those later today | |
| 09:51:03 | sean-k-mooney | i basically have 6 patches in nova that i want to try an land this cycle, those 2 for vfio-varitnt driver suport via cybrog | |
| 09:51:25 | sean-k-mooney | 2 patches that jgilaber is creating for time sliced gpus (vfio-mdev) | |
| 09:51:38 | sean-k-mooney | and then 2 for ironci start up time | |
| 09:52:11 | sean-k-mooney | if you have time to look at any of those that woudl be great if not i will try and follow up with other to land them in time | |
| 09:52:12 | bauzas | okay, I'm pretty busy before my two-week PTO which will be on next Tuesday but I'll definitely try | |
| 09:52:29 | bauzas | thanks for the effortd | |
| 09:54:41 | sean-k-mooney | as an fyi we are also seting up devstack based nightly ci to test as much of this as possible with real hardware internally (we cant currentl report the logs externally due to internal info in the job) but on the cybrog side we have been developing a kernel module to emulsate gpus, nvme devices and eventually nics | |
| 09:55:07 | sean-k-mooney | so we will have a mix of 1st party ci and internal coverage in the next few months for this | |
| 09:56:38 | sean-k-mooney | joan will be on pto startign tomorrow for the next 3 weeks so we likey will continue the 1st party testign efforts into the start of next cycle | |
| 09:56:40 | sean-k-mooney | https://review.opendev.org/q/topic:%22cyborg-vgpu-support%22 | |
| 09:56:51 | sean-k-mooney | that is the timesliced cybrog vgpu nova patch series | |
| 09:57:09 | sean-k-mooney | again just general context for everyone | |

| 13:07:54 | tkajinam | clif, hm the failure is not reproduced in my local env (and in CI, either) | |
| 13:08:25 | tkajinam | clif, do you mind reporting a bug with a few examples of the failing tests ? | |
| 13:56:00 | sean-k-mooney | tkajinam: are you runing on an mad cpu | |
| 13:56:04 | sean-k-mooney | *amd | |
| 14:00:37 | sean-k-mooney | im running the test now locally to confirm but i also didnt see the failures on my intel cpu | |
| 14:01:37 | sean-k-mooney | and if i cat the file | |
| 14:01:39 | sean-k-mooney | [15:01:17]> cat /sys/module/kvm_amd/parameters/sev | |
| 14:01:41 | sean-k-mooney | [bat error]: '/sys/module/kvm_amd/parameters/sev': No such file or directory (os error 2) | |
| 14:02:20 | sean-k-mooney | i get an error so it would fail on this laptop if the mock didnt work | |
| 14:02:22 | sean-k-mooney | Ran: 17007 tests in 214.5597 sec. | |
| 14:02:24 | sean-k-mooney | - Passed: 16940 | |
| 14:02:26 | sean-k-mooney | - Skipped: 65 | |
| 14:02:28 | sean-k-mooney | - Expected Fail: 2 | |
| 14:02:30 | sean-k-mooney | - Unexpected Success: 0 | |
| 14:02:32 | sean-k-mooney | - Failed: 0 | |
| 14:02:34 | sean-k-mooney | Sum of execute time for each test: 3262.8758 sec. | |
| 14:02:43 | sean-k-mooney | ill try recreating the env just to make sure but on py 3.14 it seams to be working | |
| 14:03:29 | sean-k-mooney | oh | |
| 14:03:45 | sean-k-mooney | maybe this only fails on amd cpus | |
| 14:04:06 | sean-k-mooney | because we may be skiping earlier on intel before we try and read the path | |
| 14:10:03 | dansmith | succeeds on macos arm64, FWIW, so it'd have to be AMD_specific | |
| 14:10:04 | frickler | I have an VM on amd where I can reproduce this, I can give you access if that helps | |
| 14:16:10 | frickler | does this imply that all of our zuul nodes are on intel? | |
| 14:17:10 | frickler | oh, or does it need kvm enabled? maybe we can try running a tox job on a big kvm node | |
| 14:19:23 | sean-k-mooney | frickler: thre are a couple of diffent checks for sev supprot so i would not be surprised if we side step the fialign check on the amd vms as well | |
| 14:19:47 | sean-k-mooney | from pi | |
| 14:19:49 | sean-k-mooney | I found no unpatched access to /sys/module/kvm_amd/parameters/sev in the current checkout. | |
