I think it looks a bit odd to isolate the workload into a VM and then
blow a hole in the isolation by providing a "fat" RPC interface directly
to the privileged dom0 kernel.

I think you could probably present a regular VIF to the guest and use
SDN (e.g., openvswitch) to get your docker-like semantics.
