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.

That's all:
qemu-system-x86_64: block/mirror.c:864: mirror_run: Assertion `((&bs->tracked_requests)->lh_first == ((void *)0))' failed.
