Oh ya

I have completely failed to take into consideration that there are no virtual internal ethernet cross cables between the different VMs. Thanks for pointing it out.

I will try it out with my hub tomorrow and also test with my laptop as an external device.

Bear in mind I'm a Xen newbie as well ...

Are the relevant ethernet cards all connected to the same switch ?
Don't forget that the way you have this set up, inter-domain traffic
will go out through one physical port, through an external switch,
and back in via a different physical port. I would also test it for
traffic between dom-0 or a dom-u and an external device - ie make
sure you can ping between dom-0 and an external device, and between
dom-1 and an external device, etc.
