I found this happening to me as well, but the domU would be able to connect 
once I gave it an IP that was DIFFERENT from the one that was configured for 
"eth2" on the dom0 side.

Yeah, like I said above, you need to have an IP different from the one 
configured for eth2 on the dom0 side. So for example, if eth2 in dom0 is 
10.10.20.1 the IP for the new interface in domU should be 10.10.20.2 (or just 
something different).

Could you give this a shot?

Yep, this was annoying for us as well, but I wasn't going to dig through routes 
and stuff to figure it out. But like I said, even though I couldn't ping from 
dom0 the domU interface had full connectivity...
