...and in any case, this patch doesn't offer any advantage over the

-Subject: [PATCH] conf: Introduce support for UNIX domain socket as qemu netdev
- back-end
-
-Since qemu [TODO], named UNIX domain sockets can be used instead of
-TCP to establish a virtual network between VMs.
-
-The obvious difference compared with TCP is that we need pass a path
-instead of address and port.
