I just had to post a comment... I really like this software, I develop a linux distribution, and aid in the development of a few other projects, and having the ability to test installs without messing up my original system is very helpful. QEMU was easy to install, and is very easy to use. Even the accelerator was easy to install and use. 10 stars!
