Perhaps I'm totally off here, but isn't there a way to set up domUs with routing outside the xend network scripts? With bridging I use brctl and the /etc/network/interfaces file (Ubuntu/Debian distributions) to set up a bridge and define IP addresses (or DHCP) for the domUs.

If all you need is fixed IP addresses for your domUs, they can be defined in the interfaces file.

I think the shorewall firewall website has a detailed explanation on how to set up routing in Xen. IIRC it also explains how to set up a VM for routing/firewall purposes. Might be worth checking.

I'm using Xen 4.4.0.

I didn't know Xen doesn't setup the bridges anymore. The first thing I
always did was to disable Xen's scripts for setting up the bridge.
Instead, I used Gentoo's scripts for setting up the script. But as I
wrote, I'm not using bridging anymore and therefore switched from
vif-bridge to vif-route.
