Thats is about a 2 day class lecture.

Here are the basics http://en.wikipedia.org/wiki/Vt-x# Intel_Virtualization_Technology_for_x86_.28Intel_VT-x.29 http://en.wikipedia.org/wiki/Vt-x# Intel_Virtualization_Technology_for_x86_.28Intel_VT-x.29

Each subset refers to hardware features that assist in creating a VM mostly around speed since by their very nature, VM slow things down when it comes to passing information back and forth thru the hardware,
