AMSDEN, Z., ARAI, D., HECHT, D., HOLLER, A., AND SUBRAHMANYAM, P.AMD64 Virtualization Codenamed 'Pacifica' Technology: Secure Virtual Machine Architecture Reference Manual, May 2005. Technical Report SMLI TR-200-87, Sun Microsystems, Inc., Mountain View, CA, USA, 2000. We look ahead to emerging techniques for addressing this MMU virtualization problem in the context of hardware-assisted virtualization. To determine why, we study architecture-level events such as page table updates, context switches and I/O, and find their costs vastly different among native, software VMM and hardware VMM execution.We find that the hardware support fails to provide an unambiguous performance advantage for two primary reasons: first, it offers no support for MMU virtualization second, it fails to co-exist with existing software techniques for MMU virtualization. Surprisingly, the hardware VMM often suffers lower performance than the pure software VMM. However, both Intel and AMD have now introduced architectural extensions to support classical virtualization.We compare an existing software VMM with a new VMM designed for the emerging hardware support.

Virtual Machine Monitors for x86, such as VMware ® Workstation and Virtual PC, have instead used binary translation of the guest kernel code. Until recently, the x86 architecture has not permitted classical trap-and-emulate virtualization.
