[ovs-discuss] vhost communication between virtio drivers in vms

I'm trying to achieve communication across an OVS switch between to VMs
connected together via an ovs bridge. I was able to do this with a ovs
bridge with to generic libvirt 'network' types. I'm failing to replicate
using DPDK vhost.
In libvirt 'network' scenario vnet[0,1] ports are added to the bridge that
also has a port for the physical NIC on the system. The switch defaults to
its L2 function and I can access the system's IP addresses.
In the DPDK vhost scenario, the client server connections get made, but the
host running the switch doesn't put the ports on the IP stack. I haven't
been able to route a packet between the VMs. Do I need to create "flows"
to mimic a single wire type of connection? I don't need L2 function, but I
did think it might be possible to move IP packets through DPDK. Any
