No netwrok after clone/copy using VMWare ESX

After making a copy/clone of an ubuntu server 8.10, i face a network problem.

1. "ifconfig" shows no eth0 device, just the 127.0.0.1 loopback
2. "/etc/init.d/networking restart" reports:

SIOCSIFADDR: No such device
eth0: ERROR while getting interface flags: No such device
SIOCSIFNETMASK: No such device
SIOCSIFBRDADDR: No such device
eth0: ERROR while getting interface flags: No such device
Failed to bring up eth0.

Solution
When you create a complete clone/copy of your vmware machine, a new ethernet MAC address is assigned.

follow this step :
as a root
run this CLI

# rm -fr /etc/udev/rules.d/70-*
# reboot

after wakeup, try ifconfig.
now you get your network back.

Salud!
