I built host and guest kernels with the patches and pinned a while(1) and the CPU thread from qemu to CPU 2 on the host. I then started the same while(1) process in guest and verified that I see ~50% steal time reported. I then built 2.6.39 (just the code I had present) on the guest and time it while it was competing with the while(1) on the host for CPU time. Next I built the guest kernel with STEAL_TIME=N and reran the kernel compile to make sure that there weren't any huge variations in performace. Eric
