AMD's Pacifica revealed in full

"Pacifica has an advantage in that the AMD64 architecture, as implemented on the K8 family of chips, all have a memory controller on the CPU. This allows Pacifica to pull some tricks, and those tricks are found in two new memory modes called Shadow Page Tables and Nested Page Tables. Both allow Pacifica to do in hardware much of what VT needs to do in software."
