Intel® Virtualization Technology
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) Intel® 64 and Intel® Architecture (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) extends Intel® VT-x by adding hardware assisted support to improve I/O device Virtualization performance.
Intel® VT-x specifications and functional descriptions are included in the Intel® 64 Architectures Software Developer’s Manual, Volume 3. Available at:
