During a single-cell adoption testing (also as documented in the guide), the creation of custom services no longer happens. This works for single-cell by a chance(?), but would not for a multiple cells case.

Alternatively, (and ideally) we should only specify "edpmServiceType: nova" for all cells, with no custom osdp services to be created as well. This simple auto-templating for dataSources should be covered in nova-operator and openstack-operator (the dataplane part of it), when it processes the cells templates perhaps.
