Nevertheless, it's pretty simple to map a running domain name to a qemu PID, by parsing the '-name' parameter from the process list. eg the following works for simple names (no spaces, metachars etc): $ sudo virsh list --all  Id Name                 State ----------------------------------  2 builder-rhel6        running $ ps ax | grep '[-]name builder-rhel6' | awk '{print $1}' 2311 Rich.
