fence_virt - Fence agent for virtual machines

fence_virt is an I/O Fencing agent which can be used with virtual machines.

NOTE: reboot-action does not power on nodes that are powered off.

fence_virt accepts options on the command line as well as from stdin. Fenced sends parameters through stdin when it execs the agent. fence_virt can be run by itself with command line options. This is useful for testing and for turning outlets on or off from scripts.
