Comment 5 for bug 1850928

Hello Thomas:

According to the log reported in the description, the backend used is slqlite
```
oslo_db.exception.DBNonExistentTable: (sqlite3.OperationalError) no such table: ml2_geneve_allocations [SQL: 'SELECT ml2_geneve_allocations.geneve_vni AS ml2_geneve_allocations_geneve_vni, ml2_geneve_allocations.allocated AS ml2_geneve_allocations_allocated \nFROM ml2_geneve_allocations'] (Background on this error at: http://sqlalche.me/e/e3q8)
```

Is that correct? In upstream CI we are testing PostgreSQL and MySQL, and with [1] MariaDB. But we don't test sqlite and there is no official support for a DB backend used for testing, not for production.

Can you swap to another backend?

Regards.
