Intel Virtualization Technology for x86 (Intel VT-x)

Intel Virtualization Technology for x86 (Intel VT-x)

Previously codenamed "Vanderpool", VT-x represents Intel's technology for virtualization on the x86 platform. Intel includes Extended Page Tables (EPT),[3] a technology for page-table virtualization,[4] in the Nehalem architecture.[5][6]

As of 2009 not all recent Intel processors support VT-x. Intel uses the feature to segment its market.[7] Support for VT-x may even vary between different versions (as identified by Intel's sSpec Number) of the same model number. [8] The following is a partial list of Intel processors include support for VT-x.[9] For a complete and up-to-date list see the Intel website. [10]
