This is a quick heads up that once this nova change merges: https://review.openstack.org/#/c/425806/ The n-cpu service will fail to start in dsvm jobs unless the placement-api service is also enabled, which it is by default in devstack: https://github.com/openstack-dev/devstack/blob/0c6956862e6ac1cdb51b674c872183074df98c50/stackrc#L58 This is the warning in case you've been overriding services but you're still running nova in your dsvm CI jobs. -- Thanks, Matt Riedemann
