Andrei - You have lost me here, what do you mean "eth0:novaExt" does not exist? I created this interface with YaST2->System->Network Settings->Overview tab->Edit eth0->Address tab->Additional Addresses->Add and filled in the popup dialog fields for "Address label", "IP Address", and "Subnet Mask". Doesn't YaST2 set this up as an additional interface using the "Address label" name I gave it, which in this case was "novaExt"? The derived name for this interface then became "eth0:novaExt". I can certainly ping it and do other network tasks via this interface label. So in many ways, at least, this label for a network interface does feel like it exists! Thanks again, Marc...
