OpenStack Diablo on Ubuntu 11.10 w/MySQL

If you’re installing the OpenStack cloud computing platform “Diablo” release on Ubuntu 11.10 server using the official guide and are using MySQL, don’t forget to:

sudo apt-get install python-mysqldb

The “glance” package (and probably others) are configured to use SQLite by default and do not automatically install this dependency by default. Unfortunately, the November 2011 version of the manual also fails to mention this and the log file (/var/log/glance/registry.log) prints a variety of “INFO [sqlalchemy.engine.base.Engine…” messages but no warnings or errors. I assume a corresponding comment applies to PostgreSQL as well but have not confirmed.
