This is due to the fact that vexxhost is consider an rh-cloud and https://github.com/openstack/tripleo-ci/blob/master/roles/common/vars/main.yaml#L52 expects an a file toci-quickstart/config/testenv/{{ environment_type }}-{{ rhcloud }}.yml which woudl resolve to vexxhost-standalone - and that does not exist.
