The image referenced in MAO for machine-api-provider-openstack is a quay repo and not an svc.registry.ci.openshift.org image reference. This needs to be replaced by a valid image managed by ART, which is in progress here https://issues.redhat.com/browse/ART-3562.
Setting the qe_test_coverage+ flag since I believe there's already checks in place to validate the image comes from a trusted source.
