the "bench.c" shown in the videos is a file I created in order to have something to add to the mounted image for the purposes of demonstration.

Thanks for taking the time to create them. Could you find an appropriate place on the wiki and add the videos to the pages? One of the other things that comes up rather frequently is how to put new benchmarks on the disk image. You mention some ideas of how to do this in the video (although I'm not sure how wget or scp would work from within the simulator since there isn't a working way to attach the simulator to an external network, although you can attached two simulated systems together). If you looking for more ideas for other tutorial videos that one that illustrated how to add files to the disk image would be great. A little known but very useful fact is if you have the qemu-user-static package installed on ubuntu you can actually chroot to a mounted disk image and manipulate it pretty much the same way would would on a real system (apt-get packages, compile code, etc). A video on doing that would be wonderful.

Please let me know if you have comments or suggestions. What other tutorials would be useful?
