And when you have a spare moment you like to setup clusters of Ubuntu machines to test out different HA systems and techniques. Okay so your not like me but you like the idea of being able to quickly clone a that Parallels Ubuntu machine you’ve painstakingly setup.

Like any sane person would do when you see the ‘clone’ command in Parallels you think your problems are solved and its almost Mojito time. #FAIL. You start your newly cloned VM and its network card sits lifeless. It’s tube inexplicably tied. Fear not because the solution is simple!

Problem

Your Ubuntu machines MAC Address has changed so it can no longer properly initialize its network card.

Solution

Removing the file containing the conflicting MAC addresses will force the system to regenerate the file with the proper settings.

Before shutting your system down to be cloned, or in my case turned into a Template, simply run this command to delete the file.

rm -fR /etc/udev/rules.d/70-persistent-net.rules

On next boot your system will notice its absence, regenerate it, and your off to the races, or at least connected to your network again.
