        description:
            - Should the Virtual Machine be running/stopped/present/absent/suspended/next_run/registered/exported.
              When C(state) is I(registered) and the unregistered VM's name
              belongs to an already registered in engine VM in the same DC
              then we fail to register the unregistered template.
            - I(present) state will create/update VM and don't change its state if it already exists.
            - I(running) state will create/update VM and start it.

            - Please check I(notes) to more detailed description of states.
            - I(exported) state will export the VM to export domain or as OVA.
