Intel® Virtualization Technology (Intel® VT)
Intel Virtualization Technology (Intel VT) is the technology that makes a single system
appear as multiple independent systems to software. This allows multiple, independent
operating systems to be running 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-x)
added hardware support in the processor to improve the virtualization performance and
robustness. Intel Virtualization Technology for Directed I/O (Intel VT-d) adds chipset
hardware implementation to support and improve I/O 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

.

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 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 operating systems 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.
