  $SCRIPT_NAME: provisions a virtualbox VM"

  Usage:

     $SCRIPT_NAME VM_NAME [DVD_PATH|--] [OS_TYPE] [RAM_SIZE] [HDD_SIZE] [NUM_CPUS] [VRDE_PORT]

     To provision from ISO:

        $SCRIPT_NAME vm1 path/to/filename.iso

     To provision from PXE:

        $SCRIPT_NAME vm1 --

     To provision using defaults, except for a later argument:

        NUM_CPUS=3 $SCRIPT_NAME vm1

     After provisioning the VM, use normal VirtualBox commands to use it:

       VBoxManage startvm vm1 -type headless  # Start the VM
       VBoxManage controlvm vm1 poweroff      # Shutdown the VM
       VBoxManage controlvm vm1 reset         # Reboot the VM
       VBoxManage unregistervm vm1 --delete   # Delete the VM

   WARNING: If VM_NAME already exists, it will be destroyed and re-provisioned!
