Overview
The configuration files corresponding to the network interfaces are located in /etc/sysconfig/network-scripts.
ifcfg-eth0 example:
DEVICE="eth0" NAME="eth0" TYPE="Ethernet" ONBOOT="yes" IPADDR="192.168.1.9" NETMASK="255.255.255.0" PREFIX="24" GATEWAY="192.168.1.1" DNS1="192.168.1.1" BOOTPROTO="none" DEFROUTE="yes" IPV4_FAILURE_FATAL="no" IPV6INIT="yes" IPV6_AUTOCONF="yes" IPV6_DEFROUTE="yes" IPV6_FAILURE_FATAL="no" IPV6_PEERDNS="yes" IPV6_PEERROUTES="yes" IPV6_PRIVACY="no"

IPADDR="172.20.1.3" NETMASK="255.255.0.0" PREFIX="16"
Configure a Network Interface after Cloning a VM Image
You want to generated a different Mac address when cloning an image, to avoid collisions.
If "HWADDR" is set pointing to the old hardware address, we want to remove it from the cloned configuration file, because if it stays there, and the hardware address is not available, the interface won't start.
