x86 virtualization is the use of hardware-assisted virtualization capabilities on an x86/x86-64 CPU.. In the late 1990s x86 virtualization was achieved by complex software techniques, necessary to compensate for the processor's lack of hardware-assisted virtualization capabilities while attaining reasonable performance.
Rapid Virtualization Indexing (RVI), known as Nested Page Tables (NPT) during its development, is an AMD second generation hardware-assisted virtualization technology for the processor memory management unit (MMU). [1] [2] RVI was introduced in the third generation of Opteron processors, code name Barcelona. [3]
AMD Turion 64 X2 engineering sample, 1.6 GHz. Turion 64 X2 is AMD's 64-bit dual-core mobile CPU, intended to compete with Intel's Core and Core 2 CPUs. The Turion 64 X2 was launched on May 17, 2006, [2] after several delays. These processors use Socket S1 and feature DDR2 memory. They also include AMD Virtualization Technology and more power ...
Instruction set extensions that have been added to the x86 instruction set in order to support hardware virtualization.These extensions provide instructions for entering and leaving a virtualized execution context and for loading virtual-machine control structures (VMCSs), which hold the state of the guest and host, along with fields which control processor behavior within the virtual machine.
^ OS-level virtualization is described as "native" speed, however some groups have found overhead as high as 3% for some operations, but generally figures come under 1%, so long as secondary effects do not appear. ^ See [20] for a paper comparing performance of paravirtualization approaches (e.g. Xen) with OS-level virtualization
Xen, a virtual machine monitor, can run in HVM (hardware virtual machine) mode, using Intel VT-x or AMD-V hardware x86 virtualization extensions and ARM Cortex-A7 and Cortex-A15 virtualization extensions. [23] This means that instead of para-virtualized devices, a real set of virtual hardware is exposed to the DomU, enabling it to use real ...
Secure Virtual Machine, a virtualization technology by AMD; Shared Virtual Memory, another AMD technology for computation on its GPUs with HSA/ROCm. Solaris Volume Manager, software; Space vector modulation, in power electronics, a modulating technique to give power to a load; Support vector machine, a machine learning algorithm
Blue Pill originally required AMD-V (Pacifica) virtualization support, but was later ported to support Intel VT-x (Vanderpool) as well. It was designed by Joanna Rutkowska and originally demonstrated at the Black Hat Briefings on August 3, 2006, with a reference implementation for the Microsoft Windows Vista kernel.
