Yes, I´ve done that:

root@xen-hypervisor:~# ifconfig
eth0 Link encap:Ethernet HWaddr 00:16:3e:63:29:ab

But it appears that the link to dom1 inside dom0 is wrong:

vif1.0 Link encap:Ethernet HWaddr fe:ff:ff:ff:ff:ff
inet6 addr: fe80::fcff:ffff:feff:ffff/64 Scope:Link

Am I right? If yes, it is configurable through xend-config.sxp ?

Thank you!

Sorry, vifX.Y devices are 'fe:ff:ff:ff:ff:ff'. So long as the eth0 inside each domU is unique, you are ok.

Do you have any firewalls running? What does 'iptables-save' show on dom[013]?
