QEMU: Virtualization the easy way
If you run a modern Linux distribution, chances are that you already have all the necessary tools to run other distributions or even proprietary operating systems as well, all at the same time. You don’t have to be a kernel hacker to do this - just follow some simple steps explained here to get going.
If you don’t already have QEMU installed, you can get it together with a graphical “launcher” for your virtual machines and a kernel-based accelerator package like this:
sudo aptitude install --with-recommends qemu qemu-launcher kqemu-modules-$(uname -r)
