You can configure OpenStack Compute to use any SQLAlchemy-compatible database.
The database name is nova. The nova-conductor service is the only
service that writes to the database. The other Compute services access
the database through the nova-conductor service.
To ensure that the database schema is current, run the following command:
# nova-manage db sync
If nova-conductor is not used, entries to the database are mostly
written by the nova-scheduler service, although all services must
be able to update entries in the database.
In either case, use the configuration option settings documented in Database configurations to configure the connection string for the nova database.
