   Yes, I have. The secret isn't really in the config files,
unfortunately. A quick run-down to what I do:

 - Modify network-route to add the following line:

   iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

 - Configure xend to use vif-route and network-route as the networking
scripts. (and restart xend to pick up the new configuration)

 - Then bring up your domU, and -- the main problem -- fix the network
configuration in the dom0 by taking down the unused vif interface, and
configuring the tap interface instead:

   ifconfig vif1.0 down
   ifconfig tap0 10.16.0.3 netmask 255.255.255.0 up

   Your network configuration and devices may be different -- tweak as
appropriate. Note that the IP address on tap0 should be in the same
network as the domU machine. I use 10.16.0.1 for the tap0 device, and
10.16.0.2 for the domU's network configuration.

   Hugo.
