The bridge should be called xenbr0, the stubdom's network interface
(that should probably called eth0) should be added to the bridge at boot
time.
Like you said, when qemu starts is going to create a tap interface, on
Linux usually we rely on a udev script to add the tap interface to the
bridge. The script is tools/hotplug/Linux/vif-setup, that calls
tools/hotplug/Linux/vif-bridge.
So at the end you have:
xenbr0 (bridge)

eth0 |
(stubdom network interface) tapXX
(qemu's tap interface)
