NAME

       fence_virsh - Fence agent for virsh

DESCRIPTION

       fence_virsh is an I/O 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.

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