module: ovirt_snapshot_facts
short_description: Retrieve information about one or more oVirt/RHV virtual machine snapshots
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_snapshot_info) instead.
description:
    - "Retrieve information about one or more oVirt/RHV virtual machine snapshots."
notes:
    - "This module returns a variable C(ovirt_snapshots), which
       contains a list of snapshots. You need to register the result with
       the I(register) keyword to use it."
options:
    vm:
        description:
            - "Name of the VM with snapshot."
        required: true
    description:
        description:
            - "Description of the snapshot, can be used as glob expression."
    snapshot_id:
        description:
            - "Id of the snapshot we want to retrieve information about."
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 snapshots which description start with update for VM named centos7
  ovirt_snapshot_info:
    vm: centos7
    description: update*
  register: result

- name: Print gathered information
  ansible.builtin.debug:
    msg: "{{ result.ovirt_snapshots }}"

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