Yes. Yunhong test Win2k8, and found in Win2k8 data center version, cpu hotplug 
successed for _SB definition, but failed for _PR definition. (success mean, 
after we hot-add vcpu, the device manager will shown new processor, but the 
task manager has no changes, same as 
http://www.boche.net/blog/index.php/2009/05/10/vsphere-memory-hot-add-cpu-hot-plug/
 .Fail mean even the device manager has no changes).

Thanks,
