After cloning a virtual machine running Ubuntu Server 7.10 I found that it didn’t have any network available. Restarting networking gave:
sudo /etc/init.d/networking restart* Reconfiguring network interfaces...eth0: ERROR while getting interface flags: No such deviceSIOCSIFADDR: No such deviceeth0: ERROR while getting interface flags: No such deviceSIOCSIFNETMASK: No such deviceSIOCSIFBRDADDR: No such deviceeth0: ERROR while getting interface flags: No such deviceeth0: ERROR while getting interface flags: No such deviceFailed to bring up eth0.
The problem lies in the fact that ethernet MAC addresses are cached. You need to remove a file to clear the cached value:
sudo rm /etc/udev/rules.d/70-persistent-net.rules
After a restart of your server you should have networking back again.
I also had to edit the following files to change the static ip addresses and hostname:
/etc/hosts - change ip address and hostnames
/etc/hostname - change hostname
/etc/network/interfaces - change ip address
