Hi, I am trying to install Openstack Essex following the instructions from this link<http://docs.openstack.org/essex/openstack-compute/install/yum/content/compute-db-sync.html> . But I get an error as follows which is faced by quite a number of users based on the comments. But none of them are resolved. If anyone has any idea what may be the problem, please let me know. Thanks The error is as follows as soon as i run the *db-sync comand *during nova installation. * * *Error* *2012-10-16 11:00:57 DEBUG nova.utils [-] backend <module 'nova.db.sqlalchemy.migration' from '/usr/lib/python2.6/site-packages/nova/db/sqlalchemy/migration.pyc'> from (pid=15585) __get_backend /usr/lib/python2.6/site-packages/nova/utils.py:659 * *2012-10-16 11:00:57 WARNING nova.utils [-] /usr/lib64/python2.6/site-packages/SQLAlchemy-0.7.8-py2.6-linux-x86_64.egg/sqlalchemy/pool.py:683: SADeprecationWarning: The 'listeners' argument to Pool (and create_engine()) is deprecated.
