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. http://libvirt.org Fencing action Force Python regex for command prompt Force Python regex for command prompt Identity file (private key) for SSH Forces agent to use IPv4 addresses only Forces agent to use IPv6 addresses only IP address or hostname of fencing device IP address or hostname of fencing device TCP/UDP port to use for connection with device Login name Login password or passphrase Script to run to retrieve password Login password or passphrase Script to run to retrieve password Physical plug number on device, UUID or identification of machine Physical plug number on device, UUID or identification of machine Use SSH connection Use SSH connection SSH options to use Login name Disable logging to stderr.
