It doesn't actually go through a "real network" at all, the VM speaks 9p to the host via a virtio pipe (not sure what the technically correct term for this is) so there's none of the overhead that you'd have with emulating a network device and encapsulating it all in Ethernet/IP/TCP.

Ah right I forgot QEMU has built in 9p on Linux. Sadly it's not yet available for Windows hosts, though there's a patch in the works.

You have any suggestions for getting a foothold in the QEMU codebase?
