Works fine for me on x86_64, so it's not arch-specific.
Hmm --- do you have a strong firewall enabled on the dom0 that might be
getting in the way?

This does not look at *all* like a normal xen networking config:

this implies that eth0 is a physical device;

and then there's a vif1.0, which I assume is the one belonging to the
domU guest's back-end driver in dom0. And finally you've got

the bridge to bind them all together.
With xen, normally you have no physical eth0: eth0 is a virtual loopback
net device, the other end of which is bound to vif0.0; the original
physical eth0 is renamed to peth0; and vif0.0 and peth0 are bridged
together on xenbr0. So once I start a domU guest in such an
environment, bridging shows:
# brctl show
bridge name bridge id STP enabled interfaces
xenbr0 8000.feffffffffff no peth0
vif0.0
vif1.0
Your environment has no virtual eth0, no renamed physical peth0 and no
loopback vif0.0; it doesn't look like any of the dom0 bits that xen
tries to set up have been initialised. What sort of network config did
you have set up before starting xend? What does "brctl show" show?
