short_description: Module to manage Virtual Machines in oVirt/RHV
version_added: "2.2"
author:
- Ondra Machacek (@machacekondra)
description:
    - This module manages whole lifecycle of the Virtual Machine(VM) in oVirt/RHV.
    - Since VM can hold many states in oVirt/RHV, this see notes to see how the states of the VM are handled.
options:
    name:
        description:
            - Name of the Virtual Machine to manage.
            - If VM don't exists C(name) is required. Otherwise C(id) or C(name) can be used.
    id:
        description:
            - ID of the Virtual Machine to manage.
    state:
        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.
            - I(next_run) state updates the VM and if the VM has next run configuration it will be rebooted.
            - Please check I(notes) to more detailed description of states.
            - I(exported) state will export the VM to export domain or as OVA.
            - I(registered) is supported since 2.4.

notes:
    - If VM is in I(UNASSIGNED) or I(UNKNOWN) state before any operation, the module will fail.
      If VM is in I(IMAGE_LOCKED) state before any operation, we try to wait for VM to be I(DOWN).
      If VM is in I(SAVING_STATE) state before any operation, we try to wait for VM to be I(SUSPENDED).
      If VM is in I(POWERING_DOWN) state before any operation, we try to wait for VM to be I(UP) or I(DOWN). VM can
      get into I(UP) state from I(POWERING_DOWN) state, when there is no ACPI or guest agent running inside VM, or
      if the shutdown operation fails.
      When user specify I(UP) C(state), we always wait to VM to be in I(UP) state in case VM is I(MIGRATING),
      I(REBOOTING), I(POWERING_UP), I(RESTORING_STATE), I(WAIT_FOR_LAUNCH). In other states we run start operation on VM.
      When user specify I(stopped) C(state), and If user pass C(force) parameter set to I(true) we forcibly stop the VM in
      any state. If user don't pass C(force) parameter, we always wait to VM to be in UP state in case VM is
      I(MIGRATING), I(REBOOTING), I(POWERING_UP), I(RESTORING_STATE), I(WAIT_FOR_LAUNCH). If VM is in I(PAUSED) or
      I(SUSPENDED) state, we start the VM. Then we gracefully shutdown the VM.
      When user specify I(suspended) C(state), we always wait to VM to be in UP state in case VM is I(MIGRATING),
      I(REBOOTING), I(POWERING_UP), I(RESTORING_STATE), I(WAIT_FOR_LAUNCH). If VM is in I(PAUSED) or I(DOWN) state,
      we start the VM. Then we suspend the VM.
      When user specify I(absent) C(state), we forcibly stop the VM in any state and remove it.

      and an Ansible playbook will report this as changed."
