An Introduction to Full Virtualization With Xen (Linux.com)

George Dunlap introduces a spectrum of virtualization, on Linux.com. "At XenSummit 2012 in San Diego, Mukesh Rathor from Oracle presented his work on a new virtualization mode, called "PVH". Adding this mode, there are now a rather dizzying array of different terms thrown about -- "HVM", "PV", "PVHVM", "PVH" -- what do they all mean? And why do we have so many? The reason we have all these terms is that virtualization is no longer binary; there is a spectrum of virtualization, and the different terms are different points along the spectrum."
