Ciao David,
thank you for the answer, but...

nothing.
if I ping one ip from the other, I get:
Destination host unreachable
and tcpdump show nothing

(I can ping each other via "external" ip, the "public" ip on eth0)

by the way... if I get the IP via dhcp from eth1 interface (of the 2 VM)
I obtain always the same IP even if the macaddress are different (always
10.0.2.15)

Other ideas?

thank you.
