I'm seeing the same issue deploying to pre-installed 14.10.1 hosts using a "manual" juju environment.
After running "juju resolved keystone/0" the service shows started in juju status, however running juju add-relation keystone mysql fails and sets the agent-state of keystone to error, with an agent-state-info of 'hook failed: "shared-db-relation-changed" for mysql:shared-db'.
