As I understand, it worked for Li Ge last week while I was at LWE, so I
should start with Friday's build.

The machine uses eth1, so I changed this line in the network-bridge
script:
netdev=${netdev:-eth1}

Q. Do I also need to change this line (line #191) in the current script
in unstable (I tried both eth0 and eth1--both times networking stopped):
ip link set veth0 name eth1
