3.0Technologies

This chapter provides a high-level description of Intel technologies implemented in the processor.

The implementation of the features may vary between the processor SKUs.

Details on the different technologies of Intel processors and other relevant external notes are located at the Intel technology web site: http://www.intel.com/technology/

3.1Intel® Virtualization Technology (Intel® VT)

Intel® Virtualization Technology (Intel® VT) makes a single system appear as multiple independent systems to software. This allows multiple, independent operating systems to run simultaneously on a single system. Intel VT comprises technology components to support virtualization of platforms based on Intel architecture microprocessors and chipsets.

Intel® Virtualization Technology (Intel® VT) for IA-32, Intel® 64 and Intel® Architecture (Intel® VT-x) added hardware support in the processor to improve the virtualization performance and robustness. Intel® Virtualization Technology for Directed I/O (Intel VT-d) extends Intel® VT-x by adding hardware assisted support to improve I/O device virtualization performance.

Intel® VT-x specifications and functional descriptions are included in the Intel® 64 and IA-32 Architectures Software Developer’s Manual, Volume 3B and is available at:

Intel® VT-x Objectives

Intel VT-x provides hardware acceleration for virtualization of IA platforms. Virtual Machine Monitor (VMM) can use Intel VT-x features to provide an improved reliable virtualized platform. By using Intel VT-x, a VMM is:

•Robust: VMMs no longer need to use paravirtualization or binary translation. This means that off-the-shelf operating systems and applications can be run without any special steps.

•Enhanced: Intel VT enables VMMs to run 64-bit guest operating systems on IA x86 processors.
