closedauto_review:"Failed to find an available port: Address already in use" Fix issues in Mojo::IOLoop::ReadWriteProcess leading to broken workers due to leftover QEMU processes
0%
Description
The worker's logic to prevent job execution when the QEMU from the previous test run hasn't been terminated was broken (see #56993).
This has already been fixed but showed that Mojo::IOLoop::ReadWriteProcess is unable to stop QEMU in all cases. Even with version 0.24 I could reproduce that very sporadic issue (on my Tumbleweed system).
I also observed that the CGroup feature might be broken, see my comment in #56993:
With this fix it at least creates the cgroup and passes it to the Mojo::IOLoop::ReadWriteProcess::Container thing. But I've just checked whether this has any actual influence on the cgroup tree (systemd-cgls) but it seems isotovideo and its forks including QEMU are just within the usual session-2.scope.
The could be the cause why Mojo::IOLoop::ReadWriteProcess is sometimes unable to stop QEMU.

@mkittler can you try to update this ticket according to https://progress.opensuse.org/projects/openqav3/wiki/#Defects , especially how to reproduce as you mentioned you managed to reproduce it locally.

We haven't seen this for long also after we worked on proper termination of processes. And also even more so mkittler recently did related changes as well that can help in this direction: https://github.com/os-autoinst/os-autoinst/pull/1439
So I consider this resolved.
