Yes, it works.

Now I have drbd up and running under domU.

Just to give a complete information to have drbd work on his iface 
(eth1) before booting I give also the following commands:
/etc/init.d/xend start (This create bridge xen-br0 with eth0)
/etc/xen/scripts/network start bridge=xen-br1 netdev=eth1 antispoof=no
(the last one create a new bridge for eth1).

Thaks a lot
