[ClusterLabs] question about fence-virsh

[Andrew Kerber]

Thanks for the answer, but thats not the problem.  I dont have access to
the console, its a security issue.  I only have access within the virtual
machines, so I want to send the reboot command within the virtual machine,
not to the console. Typically our hangups are such that the reboot command
works, and the machine hangs at starting back up, and I get an admin to go
hit the console.
