It's possible that the nova-api-metadata will startup during the time that the nova-conductor processes on the nova-cloud-controller units are still starting up, resulting in a messaging timeout which causes the daemon to exit 0. Upstart will restart a service in this scenario, however systemd is configured in packaging to only restart 'on-failure' so will not attempt to restart. This points to two other bugs - one that a messaging timeout results in a exit code of 0, and that the OpenStack services under systemd behave differently to under upstart. Install an override file for systemd based installs to mimic the behaviour of upstart, and deal with a code logic problem in the restart_trigger handling to ensure that the charm does at least try to restart the nova-api-metadata service at the right points in time.
