[one-users] Run the VM on another data center

[Javier Fontan]

OpenNebula does not have any feature that eases this VM migration.
Moreover, a suspended VM have some fixed information that may make it
behave incorrectly or even unable to run in other installation:

  * The checkpoint has the disk locations hardcoded. The images should
be in the very same path in the new cluster.
  * Bridge name is also written in the checkpoint file, it should
exist in the new cluster hosts.
  * IP is already configured in the saved VM. You will probably have
to reconfigure it after the VM is running.
  * The checkpoint file is specific for each hypervisor. It could
happen that a checkpoint made in one version of the hypervisor is not
compatible with a different version of such hypervisor.
  * Different CPUs can also make the VM crash or run erratically.

To do this migration I think it is better to save the disks of the VM,
import them in the new OpenNebula and create a new one.
