As of today, nova-compute can access data only through conductor. You should not have database connection details in nova.conf for nova-compute - if you do, this should raise an exception. However you're referring the Pike release and back then having db details in config wasn't considered as error at least. But I still doubt that nova-compute was accessing DB directly even then. пн, 9 янв. 2023 г., 18:04 Huy Võ Lê <volehuy1998 at gmail.com>: > Hi, I have a question about Nova role > > > - Assert: I don't understand about OPS/Redhat explaination.
