Description

Example: A VM that uses managed storage is stopped. The VM is then started on a different host in the same cluster. The Start operation fails.

To get around this issue, you must either start the VM up on the same host or on a host in a different cluster.

The reason is due to a slightly erroneous check in VolumeOrchestrator.prepare.

To solve this issue, we should be checking if the cluster ID changes, not if the host ID changes.
