By taking a look at job history:
https://zuul.opendev.org/t/openstack/builds?job_name=tripleo-ansible-centos-8-molecule-tripleo_metrics_qdr&project=openstack/tripleo-ansible
It is broken from long time.
It is blocking migration of jobs from cs8 to cs9. https://review.opendev.org/q/topic:unified_mol_config
Adding this bug to track the issue.
