Cloning Ubuntu Server 7.10 on VMware ESX
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 device 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 eth0: ERROR while getting interface flags: No such device Failed 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
