that's because i installed openstack changing only the hostname with the hostname command and not in /etc/hostname, laters i've changed that and restarted, now i see services from both the old and new host.
Is there a way to remove those services from the hostname Ubuntu-1204-precise-64-minimal?

Regards

Alessandro
