Hello, Shailabh and Hubertus.
Thanks for your comments.
I have tried to apply CKRM-Core and CPU-Resource-Controller patchs to
original 2.6.8.1 kernel.
Then, this patched kernel was booted up on my desktop.

Of course, the above fair-scheduling is available and fine.
But my problem was whether the vanilla SuSE9ES kernel make it possible to
control
the CPU-resource,etc... or impossible, Since it's hopeful for me not to apply
additional patches and not to rebuild.
Thanks.
