I'm working on a patch that adds a column to the compute_nodes table in the nova db, but it seems my db migration script fails when calling 'db sync' in stack.sh. I tried running the command manually, same failure:
stack@virt71:~> /opt/stack/nova/bin/nova-manage --debug -v db sync2012-07-16 21:42:52 DEBUG nova.utils [-] backend <module 'nova.db.sqlalchemy.migration' from '/opt/stack/nova/nova/db/sqlalchemy/migration.pyc'> from (pid=19230) __get_backend /opt/stack/nova/nova/utils.py:484 /usr/lib64/python2.6/site-packages/sqlalchemy/pool.py:681: SADeprecationWarning: The 'listeners' argument to Pool (and create_engine()) is deprecated.

Use event.listen() self.add_listener(l) Command failed, please check log for more info I can't find anything useful in any log (/var/log/*, /opt/stack/log/*). I ran the above in strace and saw my migration script was opened and then shortly thereafter writing of "Command failed, please check log for more info" and exit(1) :). The patch also adds a 'hypervisor_type' column to the instances table, and that migration script succeeds! Any hints for debugging a db migration script?
