IMHO, the thing to do is to use different MAC addrs for interfaces on the host-side and the VM-side because those are really two interfaces interconnected by a virtual cross-over cable. ifconfig vnet3 hw ether FE:16:3E:23:F6:4E did not help either though -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
