[ClusterLabs] kvm live migration, resource moving

[Kyle O'Donnell]

Hi Rasca,

Because the command 'virsh migrate --live' command will move the vm without shutting down the guest operating system.  It transfers the running state of the vm from one host to another.

It is not clear to me why you need to do things by hand. Why are you
using virsh once you could do a resource move within the cluster?
