Glad to hear you solved it.
Looking at your brctl output,

# brctl show xen-br0
bridge name     bridge id               STP enabled     interfaces
virbr0          8000.feffffffffff       yes             vif22.0
xenbr0          8000.feffffffffff       no              peth0
                                                        vif0.0
Seems that your domU is attached to virbr0, which is (if I'm not
mistaken) a host-only or NAT network. xenbr0 on the other hand is
attached to real eth0, which is what you want.

You might want to manually assign MAC address so it stays the same for
that domU.
Something like

vif = [ 'mac=00:16:3E:XX:XX:XX, bridge=xenbr0' ]

MAC starting with 00:16:3E is reserverd for Xen
