Hi, Eyal has been working on ovirt-engine for a while now and is currently the most prolific active contributor from the storage team. As such, I would like to propose Eyal as an ovirt-engine maintainer

with dns/dig failures that cause the engine VM to go down, and it's similar, but different. dig didn't fail (it now uses TCP), but something else caused the agent to stop the engine VM - a combination of high cpu load and low free memory, after restarting the engine VM as part of test_008. https://jenkins.ovirt.org/job/ovirt-system-tests_he-basic-suite-master/2126… :

than local score, shutting down VM on this host ===================================================================================== I looked a bit at /var/log/messages of the host, and while there is quite some noise there, can't tell specifically what might have caused the high cpu load. Also looked at logs of previous runs, and there is indeed a similar pattern, where the cpuload on the host causes the agent to penalize the score, but according to the agent log the load goes down faster, up to the point of being quite low when the engine is up, and only then we exit global maintenance, allowing the agent to take actions. I now ran it again, but think that otherwise I'll ignore this for now, unless we see more similar failures. If we do, we might want to check/monitor/log the cpu load on the hosts, and/or change test_008 to wait, after the engine is up, until the cpu load on the host goes down a bit. Before the port to pytest we waited a hard-coded 5 minutes and I changed that then to only wait until the engine VM is not migrating, and this worked more-or-less ok. We might need to refine that, although I'd rather not introduce another arbitrary long delays but wait for some condition. I also noticed that this ran was started at "03:04 AM" (UTC), by timer, whereas all previous timer-based runs started at 01:55 AM, somewhat earlier - perhaps there are some other things that run at that time that cause load.

ovirt-engine-sdk repository changes
by Martin Necas 09 Aug '21

09 Aug '21

Hi, just bit summary of few changes in ovirt-engine-sdk repo [1]. There was the decision to split the SDK generator and the python SDK itself. So we created a new repository on GitHub called python-ovirt-engine-sdk4 [2]. We switched from Travis CI to GitHub Actions, because Travis no longer supported .org domain where we had our tests. The GitHub Actions automatically builds the SDK and pushes it to the new repo similar to the Go SDK. There were some issues with the documentation generator [3] so we switched to the new version of pdoc [4]. We migrated the SDK examples because the examples have nothing to do with the generator itself moved it to the new repository [6].

OST: How to run ost.sh with a local custom repo?

Hi, when I try to run ost.sh on a local repo with --custom-repo=file:///home/pdm/rpmbuild/repodata/repomd.xml, I get the following error: requests.exceptions.InvalidSchema: No connection adapters were found for 'file:///home/pdm/rpmbuild/repodata/repomd.xml I tried using file:/home/... and /home/... but neither works. https://... works fine. How can I run the script with a custom repo in a local directory? Thanks, Milan

lago is dead, long live ost!
by Michal Skrivanek 04 Aug '21

04 Aug '21

Hi, we worked for a while on removing our dependency on lago that has been more or less abandoned for a long time now. We got to the minimal feature set that is simple to replace with bunch of virsh commands, and most of the advanced logic is implemented in pytest. We’ve just merged the last patches that freed us up from lago for local and beaker CI runs. There’s a new ost.sh wrapper for the simple operations of running the suite, inspecting the environment and shutting it down. Hopefully it’s self explanatory…. ./ost.sh command [arguments] run <suite> <distro> [<pytest args>...] initializes the workspace with preinstalled distro ost-images, launches VMs and runs the whole suite add extra repos with --custom-repo=url skip check that extra repo is actually used with --skip-custom-repos-check status show environment status, VM details shell <host> [command ...] opens ssh connection console <host> opens virsh console destroy stop and remove the running environment Right now lago and run_suite.sh still works and it is still used by the mock-based jenkins.ovirt.org runs. It will go away in future. Thanks, michal
