Ok, I'm running kvm-50 again and looking at my cpu usage and it's about the
same as what I'm seeing on 51. However, I did upgrade my fedora 7 kernel
since running kvm-50 so I think that probably explains the cpu usage part.
And it's not that the cpu usage is high by any means, just that it was
really low on my previous kernel.
