OVN_Northbound database schema This database is the interface between OVN and the cloud management system (CMS), such as OpenStack, running above it. The CMS produces almost all of the contents of the database. The ovn-northd program monitors the database contents, transforms it, and stores it into the OVN_Southbound database. We generally speak of ``the’’ CMS, but one can imagine scenarios in which multiple CMSes manage different parts of an OVN deployment.
