SIOCSIFADDR: No such device after cloning VM


When you cloned a VM from another machine, or migrated from another VM solution such as Xen, when you start the networking, you might encounter the problem of "SIOCSIFADDR: No such device eth0".

This is because the MAC address of your VM has changed!

To solve it, just enter the command below:

# sudo rm /etc/udev/rules.d/70-persistent-net.rules

Restart your VM and should be okay now.
