If you run 'hosted-engine --deploy', it creates a VM for you and it
installes the engine there.
You can check it running hosted-engine --vm-status

Instead if you directly run engine-engine setup on bare metal you are going
to directly install the engine on bare metal.
In that case you the server where you install the engine has no direct
access to the LUN used to create the storage domains.
