As you've already noticed, the network-bridge script will rename eth0 to
peth0 and create a bridge device named 'eth0'.
Moreover, it's the dummy interface you want to be used for networking.
So you should call network-bridge with netdev=dummy0.
But I remember dimly that I once tried something similar without success.

That's the wrong bridge device. Don't set bridge 'bridge=...' at all
unless you use your own scripts to create a bridge with a different name
than the default Xen-scripts expect.
If you don't want to dig deeply into the Xen networking scripts, you're
probably better off by assigning eth0 a fixed IP and using that as
