This paper describes an Intel® Virtualization Technology (Intel® VT) enhancement for future Intel® processors. This feature, referred to as timestamp-counter scaling (TSC scaling), further extends the capability of virtual-machine monitor (VMM) software that employs the TSC-offsetting mechanism by allowing that software finer control over the value of the timestamp counter (TSC) read during guest virtual machine (VM) execution.
