Intel virtualization (VT-x)

Intel Core i7 (Bloomfield) CPU

Previously codenamed "Vanderpool", VT-x represents Intel's technology for virtualization on the x86 platform.

On November 13, 2005, Intel released two models of Pentium 4 (Model 662 and 672) as the first Intel processors to support VT-x

As of 2009 not all Intel processors supported VT-x, which Intel uses to segment its market.^[20] Support for VT-x may even vary between different versions (as identified by Intel's sSpec Number) of the same model number.^[21] [22] For a complete and up-to-date list see the Intel website.^[23]

With some motherboards, Intel's VT-x feature must be enabled in the BIOS before applications can make use of it.^[24]

Intel includes Extended Page Tables (EPT),^[25] a technology for page-table virtualization,^[26] in the Nehalem architecture.^[27][28]
