I'm not sure I can help here but you should at least attach much more
logs:

* the VMs log to start with (/var/log/libvirt/qemu)
* grep libvirtd /var/log/syslog
* audit log in case you're using apparmor

If this doesn't show anything check /etc/libvirt/libvirtd.conf on howto
increase the debugging level e.g. like

  log_filters="1:qemu"
  log_outputs="1:file:/some/where/safe.log"
