@mariolenz can you review it please?

[mariolenz]

@bardielle Are you really sure about this? This module is already far too complex IMHO, and there's vmware_vmotion for people who want to move a VM to another host.

At the moment, I'm desperately trying to find ways making this module simpler instead of adding even more features (read: complexity) to it.
