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.

Virtualization Technology (Intel

64
and IA-32 Intel® Architecture (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.
