As soon as Eric said the "Ethernet ports are coming in on eth2, eth3, 
and eth4" the light-bulb went off for me, but you beat me to it.  I can 
tell you how many times this has messed me up, usually when cloning RH VMs.

FWIW I suggest fixing the root cause so that 3 years from now you aren't 
scratching your head about where the heck eth0 went.

Later,
