I read, heard something about the Blue Pill what is exactly is that and how does it affect Hypervisor???

In relation to patch-guard, is it true that patch-guard, in part, needs to read the number of pulses generated by the clock and can patch-guard be disabled or told in effect not to read the clock?

Will, the patch-guard like technology or technologies, be implemented at the hardware level at some-point in the future?
