Comment 12 for bug 1904599

Just as a note: any log messages that indicate sqlite3 are pre-configuration of keystone. e.g. before the charms have written the config files and restarted the service. This is because the default for the packages is to start keystone, and keystone's defaults are to use a local sqlite3 database. Thus you can 'ignore' the error messages as happening before the mysql relations are made. Obviously, if there are no log messages indicating that the mysql relation was ever made, then that would be a bug.

This is true for all the services that use the mysql database; e.g. aodh, neutron-api, nova-cloud-controller, etc.
