in /etc/xend/machine.cfg, do you assign a network address?  Could you
show me what do you mean? I'm not sure if I get the point :-(

[here you explained some changes in vif-route, I did it and now the
vifXX.0 has the domU IP and not dom0, good!]

in the domU config? in the vif line? If I set up ['ip=192.168.0.0,type=ioemu'], 
after xm create NAME I get:
----
Error: Device 0 (vif) could not be connected. Backend device not found.

(Are you using the same network for domU and dom0? -192.168.1.0/24- or
are you using two different networks? -like 192.168.1.0/24 and
192.168.0.0/24?)

ok I understand (but I cannot ping it from domU to dom0 :-( )

well, I will be able to handle it in some way... after I have one
machine working :-)

Thank you a lot again, I think that I'm the last steps (I hope!)
