Intel

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 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

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

VT-x Objectives

•

Robust: VMMs no longer need to use paravirtualization or binary translation. This
means that they will be able to run off-the-shelf OSs 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. 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.

VT-x Features

•

Extended Page Tables (EPT)

— EPT is hardware assisted page table physical memory virtualization

— Support guest VM execution in unpaged protected mode or in real-address

mode

— It eliminates VM exits from guest OS to the VMM for shadow page-table

maintenance
