module: ovirt_storage_vm_facts
short_description: Retrieve information about one or more oVirt/RHV virtual machines relate to a storage domain.
author: "Maor Lipchuk (@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_storage_vm_info) instead.
description:
    - "Retrieve information about one or more oVirt/RHV virtual machines relate to a storage domain."
notes:
    - "This module returns a variable C(ovirt_storage_vms), which
       contains a list of virtual machines. You need to register the result with
       the I(register) keyword to use it."
options:
    unregistered:
        description:
            - "Flag which indicates whether to get unregistered virtual machines which contain one or more
               disks which reside on a storage domain or diskless virtual machines."
        type: bool
        default: false
    max:
        description:
            - "Sets the maximum number of virtual machines to return. If not specified all the virtual machines are returned."
    storage_domain:
        description:
            - "The storage domain name where the virtual machines should be listed."
extends_documentation_fragment:
- community.general.ovirt_facts

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 relate to a storage domain and are unregistered
  ovirt_vms_info:
    unregistered: yes
  register: result

- name: Print gathered information
  debug:
    msg: "{{ result.ovirt_storage_vms }}"
'''

RETURN = '''
ovirt_storage_vms:
    description: "List of dictionaries describing the VMs. VM attributes are mapped to dictionary keys,
                  all VMs attributes can be found at following url: http://ovirt.github.io/ovirt-engine-api-model/master/#types/vm."
    returned: On success.
