Title: Add unique name to virtualbox to avoid collisions.

I ran into problems with box already exists messages. I believe it would be wise to use a vvv box name to provide a unique name for this virtualbox which is unlikely to collide with any other virtualboxes on the machine.

Prior to this it was 'default'.
