description:
   - Create, start, stop and delete Solaris zones. This module doesn't currently allow
     changing of options for a zone that's already been created.
version_added: "2.0"
author:

requirements:
  - Solaris 10 or 11
options:
  state:
    description:
      - C(present), configure and install the zone.
      - C(installed), synonym for C(present).
      - C(running), if the zone already exists, boot it, otherwise, configure and install
          the zone first, then boot it.
      - C(started), synonym for C(running).
      - C(stopped), shutdown a zone.
      - C(absent), destroy the zone.
      - C(configured), configure the ready so that it's to be attached.
      - C(attached), attach a zone, but do not boot it.
      - C(detached), shutdown and detach a zone
    choices: [ absent, attached, configured, detached, installed, present, running, started, stopped ]
    default: present
