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.
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.
Parallels Workstation is the first commercial software product released by Parallels, Inc., a developer of desktop and server virtualization software.The Workstation software comprises a virtual machine suite for Intel x86-compatible computers (running Microsoft Windows or Linux) (for Mac version, see Parallels Desktop for Mac) which allows the simultaneous creation and execution of multiple ...

Hyper-V uses the VT-x on Intel or AMD-V on AMD x86 virtualization. Since Hyper-V is a native hypervisor, as long as it is installed, third-party software cannot use VT-x or AMD-V. For instance, the Intel HAXM Android device emulator (used by Android Studio or Microsoft Visual Studio) cannot run while Hyper-V is installed. [43]
Intel AMT is the set of management and security features built into vPro PCs that makes it easier for a sys-admin to monitor, maintain, secure, and service PCs. [11] Intel AMT (the management technology) is sometimes mistaken for being the same as Intel vPro (the PC "platform"), because AMT is one of the most visible technologies of an Intel vPro-based PC.
VirtualBox supports both Intel's VT-x and AMD's AMD-V hardware-assisted virtualization. Making use of these facilities, VirtualBox can run each guest VM in its own separate address-space; the guest OS ring 0 code runs on the host at ring 0 in VMX non-root mode rather than in ring 1.
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.
