What is Intel VT?
Intel VT (Virtualization Technology) is the company's hardware assistance for processors running virtualization platforms.
Intel VT includes a series of extensions for hardware virtualization. The Intel VT-x extensions are probably the best recognized extensions, adding migration, priority and memory handling capabilities to a wide range of Intel processors. By comparison, the VT-d extensions add virtualization support to Intel chipsets that can assign specific I/O devices to specific virtual machines (VM)s, while the VT-c extensions bring better virtualization support to I/O devices such as network switches.
