Thanks Miguel, if we configure it connect to a physical network and select the Data Centre Network I assume it will create the overlay network on top of that logical network.
Let me clarify; the network on top of which it sets up the overlay is defined when the host is added, and is *only* used for inter-host communication. When within the same host, it simply uses the OVS bridge. What (I think) you mean uses the localnet feature of OVN, where the packets leaving the OVS bridge are forwarded to the external logical network you configure. These 2 concepts are unrelated.
Also is there any documentation about the ovn-provider-network architecture.

Hello,
we are using oVirt-4.2.8 and I have created a logical network using the ovn-network-provider, I haven't configured it to connect to a physical network.
I have 2 VMs running on 2 hosts which can connect to each other this logical network. The only connection between the hosts is over the ovirtmgmt network so presumably the traffic is using this?
Yes, OVN sets up an overlay network on top of ovirtmgmt network.
Thanks,
Paul S.
