Thank you so much Todd,

I've read all of those links actually, and I've created a bridge xenbr0
at system level as the wiki says, but no luck with the network with
the new toolstack and xen version.

Here it is:
bridge name     bridge id               STP enabled     interfaces
xenbr0          8000.00248c08d07e       no              eth0

I don't think there is a real traffic between interfaces; it's like if there
wasn't any communication between the vif (the guest network card)
and the xenbr0 interface.
