It is only supported with type=user (aka slirp) networking.

For general purpose data channels we'd recommend using virtio-console

https://libvirt.org/formatdomain.html#elementCharChannel

eg this example shows how QEMU guest agent is configured. Just change
the target name to something for your app

  <channel type='unix'>
    <source mode='bind'
path='/var/lib/libvirt/qemu/f16x86_64.agent'/>
    <target type='virtio' name='org.qemu.guest_agent.0'
state='connected'/>
  </channel>

Daniel
