Perhaps you'll find these articles more approachable:
        Extending Xen with Intel® Virtualization Technology
        Intel® Virtualization Technology Specification for the IA-32 Intel® Architecture
There is also a recent paper about IO and virtual machines:
        Intel® Virtualization Technology for Directed I/O
