fence_virsh(8) 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.
