Comment # 1 on bug 1207889 from James Fehlig

Is this a regression? If so, can you verify if it was caused by the recent
libvirt 9.0.0 update in Tumbleweed? Does the system journal contain further
info about the umount failure? Perhaps more debug info from libvirt would help
too. E.g. the below changes to /etc/libvirt/libvirtd.conf followed by a
libvirtd restart

log_filters="1:qemu 1:util"
log_outputs="1:file:/tmp/libvirtd.log"
