Recently I've had a need for virtual machines as I have to run various distros for work-related testing. Traditionally I probably would have just chrooted all my work and called it good, but I was very busy with other things, and decided to try real VMs instead.

The problem is, I didn't want any high maintenance ones that required a lot of tweaking and configuration (like bochs or qemu) and I also didn't want any proprietary hunk of shit like VMWare. So it was with great delight that I found VirtualBox.
