OPTIONS
      -Defaults 
      [-Disks <Int32>] 
      [-centos_ver <String>] 
          Centos Version to use. 
          Must correlate with version of an available source master
      [-Desktop <String>] 
          What desktop to install.
          Can be "cinnamon" or "none" (default: "none")

          Number of nodes to install. Default is 1
      [-Startnode <Int32>] 
          Start numbering the nodes at this number.
      [-Defaultsfile <Object>]

      [-ip_startrange <Int32>] 
          Last octet of the ip address which to assign to the nodes.
          First ip assigned will be ip_startrange+startnode.

          the first IP will be X.X.X.101
          If you think this to be too confusing, just start your nodes at 0
