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 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…it. There are two options for install. * Option 1: VirtualBox repo. If you are selective or do not install Fedora updates, this is not the option for you. It will result in installation of ALL Fedora updates that your HDA requires.* Option 2: VirtualBox RPM. This will only install the RPM and any required dependencies or dependency updates your HDA requires. It is much faster and will not force ALL Fedora updates like Option 1.
