First is the oVirt engine REST API [1]. Second is to use the ovirt-provider-ovn Neutron like REST API [2]. For the Neutron API just be aware that not everything is implemented by our provider. Hopefully it helps.

If you prefer to use ansible, please find an example in https://github.com/oVirt/ovirt-system-tests/blob/master/network-suite-mas... The python module 'openstack' can be used like this: import openstack cloud = openstack.connect(cloud='ovirt') cloud.create_network('ovn_net') The configuration if the python module 'openstack' is documented in https://docs.openstack.org/python-openstackclient/pike/configuration/inde... e.g. a file clouds.yaml in the working directory with content similar to: clouds: ovirt: auth: auth_url: https://0.0.0.0:35357/v2.0 password: '123456' username: admin@internal verify: false should do the trick. Alternatively the configuration could be provided by the environment variables: OS_USERNAME, OS_PASSWORD, OS_AUTH_URL and OS_CACERT. The same configuration works for the OpenStack command line: openstack network create ovn_net Does this help you to avoid the usage of "ovn-nbctl ls-add"?
