Just a reminder, nothing novel: if you don't mind being root on the host briefly (to run ifconfig, brctl, and tunctl commands), you can create a new TAP interface (and use the file descriptor in 9vx to back a devether) and use Linux's bridging to get ethernet frames to/from the real networkinterface.
I've not tried it with 9vx but for my Qemu setup I use VDE http://vde.sourceforge.net/ You can start vblades on the tap0 and mount them in the OS on Qemu.
