The QEMU driver pre-allocates a TAP device and connects it to a bridge when using virtual networking. The FD associated with the tap device is then passed to QEMU.
When running Xen guests, Xenner needs to turn this FD back into a TUN device name. It does this by querying the hardware address of each NIC and looking for the one which matches that it expects - ie its TUN device. This obviously requires that the TUN device be configured with a MAC address though. libvirt does not currently do this. This patch fixes this and thus makes Xenner work from the QEMU driver when using virtual networking
