> Does anyone have suggestions ? Your logs show that the interface is being detected and is named 'eth0'. If you can't see eth0 at the end of the boot process, the device node has probably been renamed by udev (you should see it as eth1, e.g. in the output of "ifconfig -a"). So:
# rm /etc/udev/rules.d/70-persistent-net.rules and reboot andrea
