Eth0 disappears after cloning

When I used VMWare Cloning of Debian Gold image everything was OK except networking. Eth0 disappeared and Eth1 came up. It's due to MAC address persistent association in /etc/udev/rules.d/z25_persistent-net.rules. Solution is to avoid persistent association. If you open this file you'll see that old MAC address is associated with eth0 so you can change this MAC address. However, the easiest solution is just delete file /etc/udev/rules.d/z25_persistent-net.rules. File will be created after next reboot but with MAC address of current network card.
