You've just pointed out your own problem. Fedora/RH/CentOS network init
scripts associate the original MAC address with the network
configuration in /etc/sysconfig/network-scripts/ifcfg-eth*, and won't
touch an interface that doesn't match. Either (a) set a static MAC in
your domain configs and fix it in the interface config file, or (b)
comment out or remove the line (which starts with 'HWADDR=', I think),
and this problem will disappear.
