module: ovirt_vm_facts
short_description: Retrieve information about one or more oVirt/RHV virtual machines
author: "Ondra Machacek (@machacekondra)"
deprecated:
    removed_in: 3.0.0  # was Ansible 2.13
    why: When migrating to collection we decided to use only _info modules.
    alternative: Use M(ovirt.ovirt.ovirt_vm_info) instead.
description:
    - "Retrieve information about one or more oVirt/RHV virtual machines."
notes:
    - "This module returns a variable C(ovirt_vms), which
       contains a list of virtual machines. You need to register the result with
       the I(register) keyword to use it."
options:
    pattern:
      description:
        - "Search term which is accepted by oVirt/RHV search backend."
        - "For example to search VM X from cluster Y use following pattern:
           name=X and cluster=Y"
    all_content:
      description:
        - "If I(true) all the attributes of the virtual machines should be
           included in the response."
      type: bool
      default: false
    case_sensitive:
      description:
        - "If I(true) performed search will take case into account."
      type: bool
      default: true
    max:
      description:
        - "The maximum number of results to return."
    next_run:
      description:
        - "Indicates if the returned result describes the virtual machine as it is currently running or if describes
           the virtual machine with the modifications that have already been performed but that will only come into
           effect when the virtual machine is restarted. By default the value is set by engine."

EXAMPLES = '''
# Examples don't contain auth parameter for simplicity,
# look at ovirt_auth module to see how to reuse authentication:

- name: Gather information about all VMs which names start with centos and belong to cluster west

  register: result

- name: Print gathered information
