Several challenges were overcome in the installation process of VirtualBox 1.6 on both my desktop Dell Optiplex GX620 and my IBM Lenovo X60, both running Hardy Heron. For those who don’t know, VirtualBox is an open-source GUI interface software for building multiple virtual machines. Yes, open source meaning free. There are versions for nearly every operating system. My goal today was installing it on the Ubuntu 8.04. First was simply downloading it from the right source!
