There's a problem with virtualization. It's not a huge problem, but it's an impediment, in my opinion, to some large-scale deployments of virtualization technology across the enterprise data center. The problem is that the venerable x86 architecture wasn't designed for virtualization. Operating systems have complete control over the processor and the hardware; they understand the full instruction set, and can exercise every mode, use every interrupt, access every page of memory. That makes it hard for a virtual machine monitor (VMM) to exercise supervision over operating systems running in virtual machines, often called guest operating systems.
