Hi all,
I am trying to verify fixes for ovirt-engine-rename, specifically for
OVN. Engine top patch is [1], OST patch [2]. Ran the manual job on
these [3].
In previous patches, OST failed in earlier tests. Now, it passed these
tests, so I hope that my patches are enough for what I am trying to
do. However, [3] did fail later, during test_hotplug_cpu - it set the
number of CPUs, then tried to connect to the VM, and timed out.
The logs imply that right after it changed the number of CPUs, the VM
was rebooted, apparently by libvirtd. Relevant log snippets:
vdsm [4]:

only place in the log with '42224'. No other log there has 42224,
other than these and audit.log).
Any idea? Is this a bug in libvirt? vdsm? I'd at least expect
something in the log for such a severe step.

I’d suggest to rerun. I don’t trust the CI env at all. Could be any reason.
It’s highly unlikely to be caused by your patch, and I can see on my infra that OST is
running well on both CentOS and Stream.

New subject: Untrusted CI environment
I’d suggest to rerun. I don’t trust the CI env at all. Could be any
reason.
It’s highly unlikely to be caused by your patch, and I can see on my infra
that OST is running well on both CentOS and Stream.
If we don't trust the CI environment (I also don't really trust it that
much) why not changing it to something we can trust and rely on?

ok
I don’t trust the CI env at all. Could be any reason.
If the qemu process would have simply died, I'd agree it's likely to
be an infra issue.
But if libvirt indeed killed it, I'd say it's either a bug there, or
some weird flow (which requires more logging, at least).
It’s highly unlikely to be caused by your patch, and I can see on my
infra that OST is running well on both CentOS and Stream.
Well, also basic-suite is now passing for quite some time now without
any failures:

Is this the hosted engine vm? If we had trouble with storage, maybe
sanlock killed the vm because it could not renew the lease.
What do we have in /var/log/sanlock.log?
Also, do we have any WARN logs in vdsm? if there was an issue with
storage you would see warnings about blocked checkers every 10 seconds.

Is this from libvirt log?
Yes
Why would libvirt log log libvirtd pid?
Perhaps because it forks several children, and thus has in its logging
format string also the pid? That's standard practice.

Is this the hosted engine vm?
No, it's "vm0". (It's the basic suite, not hosted-engine).
If we had trouble with storage, maybe
sanlock killed the vm because it could not renew the lease.
What do we have in /var/log/sanlock.log?

Nothing that seems relevant - last line is:

Also, do we have any WARN logs in vdsm? if there was an issue with
storage you would see warnings about blocked checkers every 10 seconds.

Yes

Perhaps because it forks several children, and thus has in its logging
format string also the pid? That's standard practice.

No, it's "vm0". (It's the basic suite, not hosted-engine).
Maybe some tests add vm lease to this vm...

Nothing that seems relevant - last line is:
2020-06-29 10:14:29 2523 [44292]: s4:r6 resource
bdabb997-2075-4bb6-8217-b3a99d1bd599:da464550-1f81-443a-907d-39b763f13751:/rhev/data-center/mnt/192.168.200.4:_exports_nfs_share2/bdabb997-2075-4bb6-8217-b3a99d1bd599/dom_md/xleases:3145728
This is a vm lease for vm da464550-1f81-443a-907d-39b763f13751.
So theoretically this vm could be terminated by sanlock if sanlock could not
renew the lease...

20 WARN lines. Last one before the problem:
...
But none of these warnings is related, and there is nothing in sanlock
log about renewal
issues or about killing pids, so this is not the issue.
This can also be vdsm asking libvirt to terminate the vm, for example
if the vm is paused
for long time, based on the restart policy.
