short_description: Retrieve information about the oVirt/RHV API
version_added: "1.0.0"
author:
- "Ondra Machacek (@machacekondra)"
description:
    - "Retrieve information about the oVirt/RHV API."
    - This module was called C(ovirt_api_facts) before Ansible 2.9, returning C(ansible_facts).
      Note that the M(ovirt.ovirt.ovirt_api_info) module no longer returns C(ansible_facts)!
options:
    follow:
      description:
        - List of linked entities, which should be fetched along with the main entity.
        - This parameter replaces usage of C(fetch_nested) and C(nested_attributes).
        - "All follow parameters can be found at following url: https://ovirt.github.io/ovirt-engine-api-model/master/#types/api/links_summary"
      type: list
      version_added: 1.5.0
      elements: str
      aliases: ['follows']
notes:
    - "This module returns a variable C(ovirt_api),
       which contains a information about oVirt/RHV API. You need to register the result with
       the I(register) keyword to use it."

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

# Gather information oVirt API:
- ovirt.ovirt.ovirt_api_info:
  register: result
- ansible.builtin.debug:
    msg: "{{ result.ovirt_api }}"
