Thanks for comming back to me with the information.
Unfortunately this is not a full debug log but I can try to tell you
what I see here:
I configured libvirtd that way:
ha-idg-1:~ # grep -Ev '^$|#' /etc/libvirt/libvirtd.conf
log_level = 1
log_filters="1:qemu 3:remote 4:event 3:util.json 3:rpc"
log_outputs="1:file:/var/log/libvirt/libvirtd.log"
keepalive_interval = -1
That's what i found on https://wiki.libvirt.org/page/DebugLogs .
Isn't that correct ? That should create informative logfiles.
The other host has excat the same configuration but produce much bigger logfiles !?!
I have libvirt-daemon-4.0.0-8.12.1.x86_64.

So this looks like qemu crashed. Or at least it's the usual symptom we
get. Is there anything in /var/log/libvirt/qemu/$VMNAME.log?
That's all:
qemu-system-x86_64: block/mirror.c:864: mirror_run: Assertion
`((&bs->tracked_requests)->lh_first == ((void *)0))' failed.

And this looks to me as if the Abort job can't be interrupted properly
while waiting synchronously for the job to finish. This seems to be the
problem. If the VM indeed crashed there's a problem in job waiting
apparently.
I'd still really like to have debug logs in this case to really see what
happened.
I configured logging as i found on https://wiki.libvirt.org/page/DebugLogs.
What else can i do ?
