STEPS TO REPRODUCE

- name: Reproduce issue
  hosts: localhost
  tasks:
    - name: oVirt auth
      ovirt.ovirt.ovirt_auth:
        url: https://engine.company.com/ovirt-engine/api
        username: user
        password: secret

    - name: Run task with arguments found in documentation
      ovirt.ovirt.ovirt_host:
        auth: "{{ ovirt_auth }}"
        name: host-123
        password: another secret
        address: host-123.company.com
        state: present
        kernel_params:
          - intel_iommu=on
