I added the kvm_stat support to ppc to watch my guest while executing e.g. to check things like "what does my guest do when I see nothing" ;-)
To be able to do that I also needed a script that reports in a iostat/vmstat like style, because of that I wrote a small shell script.
Additionally my colleague Christian Bornträger had the need for a top style output and wrote a script for that need.
I attached both to help everyone experimenting with kvm_stat.

They are just small helpers and might still contain issues, feel free to comment, correct, whatever ;-)
