  2. Virtual 8086 mode - Wikipedia

    en.wikipedia.org/wiki/Virtual_8086_mode

    To use virtual 8086 mode, an operating system sets up a virtual 8086 mode monitor, which is a program that manages the real-mode program and emulates or filters access to system hardware and software resources. The monitor must run at privilege level 0 and in protected mode. Only the 8086 program runs in VM86 mode and at privilege level 3.

  3. x86 virtualization - Wikipedia

    en.wikipedia.org/wiki/X86_virtualization

    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 .

  4. Virtualization - Wikipedia

    en.wikipedia.org/wiki/Virtualization

    Full virtualization requires that every salient feature of the hardware be reflected into one of several virtual machines – including the full instruction set, input/output operations, interrupts, memory access, and whatever other elements are used by the software that runs on the bare machine, and that is intended to run in a virtual machine.

  5. List of x86 virtualization instructions - Wikipedia

    en.wikipedia.org/wiki/List_of_x86_virtualization...

    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.

  6. Hypervisor - Wikipedia

    en.wikipedia.org/wiki/Hypervisor

    A hypervisor, also known as a virtual machine monitor (VMM) or virtualizer, is a type of computer software, firmware or hardware that creates and runs virtual machines. A computer on which a hypervisor runs one or more virtual machines is called a host machine , and each virtual machine is called a guest machine .

  8. x86 instruction listings - Wikipedia

    en.wikipedia.org/wiki/X86_instruction_listings

    The x86 instruction set refers to the set of instructions that x86-compatible microprocessors support. The instructions are usually part of an executable program, often stored as a computer file and executed on the processor. The x86 instruction set has been extended several times, introducing wider registers and datatypes as well as new ...
