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 Intel® 64 and IA-32 Intel® Architecture (Intel® VT-x) adds hardware support in the processor to improve the virtualization performance and robustness. 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 http://www.intel.com/ products/processor/manuals/index.htm

•Intel® Virtualization Technology (Intel® VT) for Directed I/O (Intel® VT-d) adds processor and uncore implementations to support and improve I/O virtualization performance and robustness. The Intel VT-d spec and other Intel VT documents can be referenced at http://www.intel.com/technology/ virtualization/index.htm.

3.1.1Intel 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 improved reliable virtualized platform. By using Intel VT-x, a VMM is:

•Robust: VMMs no longer need to use para-virtualization or binary translation. This means that they will be able to run off-the-shelf OS’s and applications without any special steps.

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

•More reliable: Due to the hardware support, VMMs can now be smaller, less complex, and more efficient. This improves reliability and availability and reduces the potential for software conflicts.

•More secure: The use of hardware transitions in the VMM strengthens the isolation of VMs and further prevents corruption of one VM from affecting others on the same system.
