An easy way to set up and run virtual machines

Here's an outstanding article on setting up and running virtual machines. "Most of the time, one operating system per computer is enough. But on occasion, you might want to boot up a second operating system for security reasons, testing purposes, or compatibility with specific software. Technical details typically restrict that alternate OS to a single PC, however. You can only install an OS in a single location after all.

But using a fork of Oracle's popular VirtualBox virtualization software, known as Portable VirtualBox, you don't have to limit secondary operating systems to a single computer or boot it up separately from Windows. Instead, you can pack it onto a portable USB drive and load it up on any PC while Windows runs in the background, like a virtualized version of the Windows to Go option found in Windows 8 Enterprise.

Portable VirtualBox is fairly easy to set up, though it does require attention to a few key details. We'll walk you through it, and outline some of the main concerns with running a virtual machine on a portable USB drive."
