module: ovirt_scheduling_policy_facts
short_description: Retrieve information about one or more oVirt scheduling policies
author: "Ondra Machacek (@machacekondra)"
deprecated:
    removed_in: "2.10"
    why: When migrating to collection we decided to use only _info modules.
    alternative: Use M(ovirt_scheduling_policy_info) instead
description:
    - "Retrieve information about one or more oVirt scheduling policies."
    - This module was called C(ovirt_scheduling_policy_facts) before Ansible 2.9, returning C(ansible_facts).
      Note that the M(ovirt_scheduling_policy_info) module no longer returns C(ansible_facts)!
notes:
    - "This module returns a variable C(ovirt_scheduling_policies),
       which contains a list of scheduling policies. You need to register the result with
       the I(register) keyword to use it."
options:
    id:
        description:
            - "ID of the scheduling policy."
        required: true
    name:
        description:
            - "Name of the scheduling policy, can be used as glob expression."
extends_documentation_fragment:
- ovirt.ovirt.ovirt_info

'''

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

# Gather information about all scheduling policies with name InClusterUpgrade:
- ovirt_scheduling_policy_info:
    name: InClusterUpgrade
  register: result
- debug:
    msg: "{{ result.ovirt_scheduling_policies }}"
'''

RETURN = '''
ovirt_scheduling_policies:
    description: "List of dictionaries describing the scheduling policies.
                  Scheduling policies attributes are mapped to dictionary keys,
                  all scheduling policies attributes can be found at following
                  url: https://ovirt.example.com/ovirt-engine/api/model#types/scheduling_policy."
    returned: On success.
