An init.d script that can be used to overcome the MAC address changes when copying a virtual machine. This has been tested on Centos. To utilize this script, add it to init.d, then link it to rc3.d: ln -s /etc/init.d/removepersistentnetrules /etc/rc.d/rc3.d/S99removepersistentnetrules

removepersistentnetrules

#!/bin/bash

FIRSTBOOT="/etc/.firstboot"
if [ ! -f $FIRSTBOOT ];
then
  # Remove the first boot files
	rm -f /etc/udev/rules.d/70-persistent-net.rules
	
	# Restart the network service
	service network restart
	
	# Touch file so this does not run again
	touch $FIRSTBOOT 
	
	# Restart the system so that it picked up the change
	shutdown -r now
