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?ref_type=heads#L862
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?
