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.
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.

KVM provides device abstraction but no processor emulation. It exposes the /dev/kvm interface, which a user mode host can then use to: Set up the guest VM's address space. The host must also supply a firmware image (usually a custom BIOS when emulating PCs) that the guest can use to bootstrap into its main OS. Feed the guest simulated I/O.

The creation and management of virtual machines has also been called "platform virtualization", or "server virtualization", more recently. [ 2 ] [ 3 ] Platform virtualization is performed on a given hardware platform by host software (a control program ), which creates a simulated computer environment, a virtual machine (VM), for its guest ...
Mode Based Execution Control (MBEC) is an extension to x86 SLAT implementations first available in Intel Kaby Lake and AMD Zen+ CPUs (known on the latter as Guest Mode Execute Trap or GMET). [10] The extension extends the execute bit in the extended page table (guest page table) into 2 bits - one for user execute, and one for supervisor execute.
3DNow! is a deprecated extension to the x86 instruction set developed by Advanced Micro Devices (AMD). It adds single instruction multiple data (SIMD) instructions to the base x86 instruction set, enabling it to perform vector processing of floating-point vector operations using vector registers.
