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.

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.
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.
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.
