  - Fix disk multiattach with VirtualBox 6
    
    Starting with version 6.0, the behavior of VirtualBox with regards to
    disk multiattach changed.
    
    The result are error messages like:
      VBoxManage: error: Cannot change type for medium '<base_disk_path>':
      the media type 'MultiAttach' can only be used on media registered
      with a machine that was created with VirtualBox 4.0 or later
    
    The new code should work for both VirtualBox 6 and older versions.
    
    The workaround suggests that we may not be using the VirtualBox volumes
    the way they are meant to be used, but with scant documentation out
    there rewriting the volume logic may result in no improvement at all,
    so let's leave it at that for the time being.
