I have windows xp installed under xen. When the guest system is idle,xm top shows about 60% utilization. What is even more interesting, by connecting through an rdp session and moving the mouse quickly around the utilization under xen lowers to about 10%. The behaviour is also the same with GPLPV 0.9.9. It seems that this 60% is consumed while spinning inside some idle loop. I am using stock Xen 3.2.1, with an AMD Phenom 9650 CPU. How can i make windows give away unneeded cpu? Would calling HLT in a loop be a good solution, or is there some better way? Maybe there is some ready solution?
