This is just about connecting the NIC backends for 2 QEMUs together
using a UNIX socket, instead of the current TCP/UDP socket. It should be
fairly trivial to support i would expect. Though ideally we'd port the
netdev socket backend to use QIOChannel  too

  Ability to use -net socket with unix sockets

Status in QEMU:

Bug description:
  It would be a nice feature (simplifying access control for example) to
  be able to do something like:

  qemu -net socket,listen=unix:/tmp/qemunet
  qemu -net socket,connect=unix:/tmp/qemunet

  For now one has to use TCP connections even for guests running on the
  same host, which involves setting up iptables to restrict access.
