In your vif configuration, add in "model=virtio-net-pci" to specify
VirtIO net as your emulated device. You also need to add in
xen_emul_unplug=never in your *guest* kernel command line.

You might also find device_model_args= useful for appending arbitratry
arguments to QEMU. Presumably you need to append some runes to QEMU to
enable MacVtap.
