After cloning a virtual machine running Ubuntu Server 10.04 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.
