OK, network 10.1.1.0/24 with router 10.1.1.254 via eth3 (xen-br3). Both
dom0 and domU are simple hosts and don't route. Fine.

My vifX.Y always have fe:ff:ff:ff:ff:ff. Do you mean, while vifX.1 does
not get the configured MAC your vifX.0 does?

One last idea. I don't remember: Have you tried xen-br0 on eth3 and it
worked? If not, are your eth0 and eth3 NICs different hardware
models/use different device drivers? Maybe it's a NIC driver or hardware
problem. Maybe setting the NIC in promicious mode might help "ip l s
eth3 promisc on" or "ifconfig eth3 promisc". Maybe the driver is
incompatible with the bridging code.
