Perhaps you'll find these articles more approachable:
        Extending Xen with Intel® Virtualization Technology
        http://download.intel.com/technology/itj/2006/v10i3/v10-i3-art03.pdf
        
        Intel® Virtualization Technology Specification for the IA-32 Intel® Architecture
        http://www.cs.utah.edu/classes/cs7940-010-rajeev/spr06/papers/vm.pdf
        
There is also a recent paper about IO and virtual machines:
        Intel® Virtualization Technology for Directed I/O
