This patch implements live migration of instances across compute nodes.
Each compute node must be managing a cluster in the same vCenter and ESX
hosts must have vMotion enabled [1].
If the instance is located on a datastore shared between source
and destination cluster, then only the host is changed. Otherwise, we
select the most suitable datastore on the destination cluster and
migrate the instance there.
