Hello, I was wondering if any of you were able to to help me figure out why I am getting poor performance with kvm. When running windows as a guest os, when windows is idle, using 1-2% cpu, the kvm process uses about 20-30% cpu. Whenever I am doing any kind of activity (especially disk activity) its shoots right up to 99%. Anyway, have a readprofile snap shot as well as kvm stat output.
