Dear Openstack users, I am trying to install openstack on an ubuntu server 12.04, with Xen as a virtualization technology. I unfortunately got a problem while trying to install the nova service. Actually, the "nova-manage db sync" fails and returns the following warnings: ------------------------------- 2012-08-28 18:47:24 DEBUG nova.utils [-] backend <module 'nova.db.sqlalchemy.migration' from '/usr/lib/python2.7/dist-packages/nova/db/sqlalchemy/migration.pyc'> from (pid=3101) __get_backend /usr/lib/python2.7/dist-packages/nova/utils.py:658 2012-08-28 18:47:24 WARNING nova.utils [-] /usr/lib/python2.7/dist-packages/sqlalchemy/pool.py:639: SADeprecationWarning: The 'listeners' argument to Pool (and create_engine()) is deprecated.
