My guess is the new interface is called eth1, since it has a different MAC address than the old eth0 (and linux doesn't know that you are replacing it rather than supplementing it). Try editing or completely deleting /etc/udev/rules.d/70-persistent-net.rules (it will be re-created automatically after you reboot if you delete it). That's where udev decides which network device gets which name.
