On the controller node, source the credentials for a regular (non-privileged) project. The following example uses the demo project.
On the controller node, launch an instance using the UUID of the provider network.

The OVN mechanism driver and OVN perform the following operations when launching an instance.
The OVN mechanism driver creates a logical port for the instance.
_uuid : cc891503-1259-47a1-9349-1c0293876664

The OVN mechanism driver updates the appropriate Address Set entry with the address of this instance:

The OVN mechanism driver creates ACL entries for this port and any other ports in the project.

The OVN controller service on each compute node translates these objects into flows on the integration bridge br-int. Exact flows depend on whether the compute node containing the instance also contains a DHCP agent on the subnet.
On the compute node containing the instance, the Compute service creates a port that connects the instance to the integration bridge and OVN creates the following flows:
