     required: True
   state:
     description:
     - The action to take.
     - If set to C(present), then custom attribute is added or updated.
     - If set to C(absent), then custom attribute is removed.

     choices: ['present', 'absent']
   uuid:
     description:
     - UUID of the virtual machine to manage if known. This is VMware's unique identifier.
