I first heard about virtual machines about six to seven years ago. I couldn’t see a point in wanting to run another computer inside your computer. A few years ago I used VMs to test and blog about Linux distros. In the past year I’ve used it to preview new features in Fedora while the next version was in beta. This week I used them in the most useful way yet: to test server software before implementing them on my public, paid server. These were some of easiest installs I’ve ever done - even easier than Wordpress’ famous Five Minute Install.
