Since device persistence stuff is just getting in the way for these VMs, rip it out:

• Completely remove the HWADDR and UUID lines from the ifcfg file, and
• Delete /etc/udev/rules.d/70-persistent-net.rules before cloning That should let the eth0 with a new MAC address actually use the ifcfg-eth0 on initial boot.

remove the HWADDR AND UUID lines from /etc/sysconfig/network-scripts/ifcfg-eth0
