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.
AMD has published a specification for IOMMU technology, called AMD-Vi. [6] [7] IBM offered Extended Control Program Support: Virtual Storage Extended (ECPS:VSE) mode [8] on its 43xx line; channel programs used virtual addresses. Intel has published a specification for IOMMU technology as Virtualization Technology for Directed I/O, abbreviated ...
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]
List of AMD and AMD-based hardware that supports IOMMU. AMD's implementation of IOMMU is also known as AMD-Vi. [101] Please note that just because a motherboard uses a chipset that supports IOMMU does not mean it is able to and the bios must have an ACPI IVRS
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 ...
SeaBIOS is an open-source implementation of an x86 BIOS, serving as a freely available firmware for x86 systems. Aiming for compatibility, it supports standard BIOS features and calling interfaces that are implemented by a typical proprietary x86 BIOS.
Intel and AMD have introduced features to their x86 processors to enable virtualization in hardware. As well as virtualization of the resources of a single machine, multiple independent nodes in a cluster can be combined and accessed as a single virtual NUMA machine. [4]
In computing, BIOS (/ ˈ b aɪ ɒ s,-oʊ s /, BY-oss, -ohss; Basic Input/Output System, also known as the System BIOS, ROM BIOS, BIOS ROM or PC BIOS) is a type of firmware used to provide runtime services for operating systems and programs and to perform hardware initialization during the booting process (power-on startup).
