Hello,
I just hit the situation that all domains on a host where paused due to
missing space. It took me some time to figure out that there was no
space left for the images on the host. I learned that 'virsh domstate
--reason $GUEST' and 'domblkerror $GUEST' could have helped me. But the
logs are silent about the problem.
Would it be possible to show these problems in logs or is there other
documentation than the reference to find out how to troubleshoot those
issues?
Thank you
Lennart

I understand your frustration. And libvirt does indeed produce a message
into logs, but it's only a debug message:
VIR_DEBUG("Transitioned guest %s to paused state due to IO error",
vm->def->name);
See:
https://gitlab.com/libvirt/libvirt/-/blob/master/src/qemu/qemu_process.c?...
There are other events, where libvirt may pause guest (just look for 'to
paused state' within the file). All of these could be VIR_WARN() which
in default setting makes it into a log file (or log service), whereas
VIR_DEBUG() doesn't.
Care to post a patch or can I do it?

Merged. Just for the future - for libvirt itself we still use mailing
list to send patches.
