AMD virtualization (AMD-V)
AMD markets its virtualization extensions to the 64-bit x86 architecture as AMD Virtualization, abbreviated AMD-V. It is still referred to as "Pacifica", the AMD internal project code name.
AMD-V operates on AMD Athlon 64 and Athlon 64 X2 with family "F" or "G" on socket AM2 (not 939), Turion 64 X2, Opteron 2nd generation[1] and 3rd-generation,[2] Phenom, and all newer processors. Sempron processors do not include support for AMD-V.
On May 23, 2006, AMD released the Athlon 64 ("Orleans"), the Athlon 64 X2 ("Windsor") and the Athlon 64 FX ("Windsor") as the first AMD processors to support AMD-V. Prior processors do not have AMD-V.
Intel Virtualization Technology for x86 (Intel VT-x)
Previously codenamed "Vanderpool", VT-x represents Intel's technology for virtualization on the x86 platform. Intel plans to add Extended Page Tables (EPT),[3] a technology for page table virtualization,[4] in the Nehalem architecture.[5]
The following modern Intel processors include support for VT-x,[6]:
* Pentium 4 662 and 672
* Pentium Extreme Edition 955 and 965 (not Pentium 4 Extreme Edition with HT)
* Pentium D 920-960 except 945, 935, 925, 915
* some models of the Core processors family
* some models of the Core 2 processors family (list here)
* Xeon 3000, 5000, 7000 series
* some Atom chips
* all Intel Core i7 processors
Neither Intel Celeron, Pentium Dual-Core nor Pentium M processors have VT technology.
