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.
