QEMU on Windows

a fascinating program. I've always loved Virtual Machines, the concept is very amusing, in a strange way. This program simulates a small linux distribution you can run in a window.

Virtual PC is of course the most popular VM in the world, which allows you to run Windows on your Mac, or a little Windows box on your Windows box.

Why would anyone care to do this? Well, for instance you can pretend to be a whole internet, just on your very own computer, where one little VM is the server, and the other the client, or even to debug powerful parallelism code, like supercomputers use.

The more common use is just accessibility. I've used emulation layers, VM OSes, and similar to look at old files, interact with strange services, and use a feature not on my home OS too many times to count.
