Overview

This is the data structure it accepts, this is the output of #get_vm_disks:

{:disks=>
 [{:address=>0,
   :description=>"SCSI Controller",
   :name=>"SCSI Controller 0",
   :id=>2,
   :resource_sub_type=>"VirtualSCSI",
   :resource_type=>6},
  {:address_on_parent=>0,
   :description=>"Hard disk",
   :name=>"Hard disk 1",
   :id=>2000,
   :parent=>2,
   :resource_type=>17,
   :capacity=>16384,
   :bus_sub_type=>"VirtualSCSI",
   :bus_type=>6},
  {:address=>0,
   :description=>"IDE Controller",
   :name=>"IDE Controller 0",
   :id=>3,
   :resource_type=>5}]}

This is what it generates:
