The VM Configurations module allows you to view UUID and domain state of Virtual Machines. You can perform various system power options like start or resume (if VM is paused), turn off, restart or suspend (pause) a VM.
You can perform similar actions on multiple virtual machines. To do so, click on the machine names in the list. The properties box will display the domain state of the machines selected. Now, click on any of the system power actions provided at the bottom.
