Hyper-V is a native hypervisor developed by Microsoft; it can create virtual machines on x86-64 systems running Windows. [1] It is included in Pro and Enterprise editions of Windows NT (since Windows 8) as an optional feature to be manually enabled. [2]

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.
VMware ESXi (formerly ESX) is an enterprise-class, type-1 hypervisor developed by VMware, a subsidiary of Broadcom, for deploying and serving virtual computers.As a type-1 hypervisor, ESXi is not a software application that is installed on an operating system (OS); instead, it includes and integrates vital OS components, such as a kernel.

October 24, 2005 VMware releases VMware Player, a free player for virtual machines. Sun releases Solaris 10, including Solaris Zones, for both x86/x64 and ...
Each VM has a separate shadow page table and the hypervisor is in charge of managing them. While shadow page tables are faster than double translation, they are still expensive compared to not running in a virtual machine: every time a guest updates its page tables, it requires the hypervisor to also manage changes in the shadow tables.
Hardware virtualization is the virtualization of computers as complete hardware platforms, certain logical abstractions of their componentry, or only the functionality required to run various operating systems. Virtualization emulates the hardware environment of its host architecture, allowing multiple OSes to run unmodified and in isolation.
This approach is described as full virtualization of the hardware, and can be implemented using a type 1 or type 2 hypervisor: a type 1 hypervisor runs directly on the hardware, and a type 2 hypervisor runs on another operating system, such as Linux or Windows. Each virtual machine can run any operating system supported by the underlying hardware.
