This is a step by step tutorial on how to get VirtualBox 3 up and running on Fedora 12. Specifically, this guide was written using the VirtualBox 3.2.10 12 version and an i386 CPU (32-bit), but should work with all versions. It can be adapted to upcoming versions and different CPUs (64-bit). The folks at VirtualBox have made it easy to install for Fedora users and I’m going to show you how in a few easy steps. Right, open a terminal window and let’s get to it.
