START with options: --os-cloud machine network show notexisting -v
/usr/lib/python3.9/site-packages/barbicanclient/__init__.py:57: UserWarning: The secrets module is moved to barbicanclient/v1 directory, direct import of barbicanclient.secrets will be deprecated. Please import barbicanclient.v1.secrets instead.
