fence_virsh - Man Page
Fence agent for virsh
Description
fence_virsh is a Power Fencing agent which can be used with the virtual machines managed by libvirt. It logs via ssh to a dom0 and there run virsh command, which does all work.
By default, virsh needs root account to do properly work. So you must allow ssh login in your sshd_config.
The fence agent accepts options on the command line as well as from stdin. Fenced sends parameters through stdin when it execs the agent. The agent can be run by itself with command line options. This is useful for testing and for turning outlets on or off from scripts.
