xen-br0   Link encap:Ethernet  HWaddr FE:FF:FF:FF:FF:FF
          BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

bl2-1:~ # ifconfig xen-br0 up

At this point, networking is up. But we knew that--we put that on the
bug--when we manually bring up xen-br0, networking resumes. I guess the
question is why xen-br0 is not coming up.
