About Cloud


Did you know that Hyper-V has had four times the growth of VMware's ESX over the past three years? As such, virtual machine migration is an increasing priority for many customers as more and more are exploring and evaluating the Microsoft platform against their existing VMware installed base. Whether it's virtual to virtual (from one hypervisor to another) or physical to virtual, migration provides a path for consolidation of workloads and services, and the foundation for cloud.

Role and technology description

The Hyper-V role enables you to create and manage a virtualized computing environment by using virtualization technology that is built in to Windows Server. Installing the Hyper-V role installs the required components and optionally installs management tools. The required components include Windows hypervisor, Hyper-V Virtual Machine Management Service, the virtualization WMI provider, and other virtualization components such as the virtual machine bus (VMbus), virtualization service provider (VSP) and virtual infrastructure driver (VID).

The management tools for the Hyper-V role consist of:

GUI-based management tools: Hyper-V Manager, a Microsoft Management Console (MMC) snap-in, and Virtual Machine Connection, which provides access to the video output of a virtual machine so you can interact with the virtual machine.

Hyper-V-specific cmdlets for Windows PowerShell. Windows Server 2012 includes a Hyper-V module, which provides command-line access to all the functionality available in the GUI, as well functionality not available through the GUI. 


If you use Server Manager to install the Hyper-V role, the management tools are included unless you specifically exclude them. If you use Windows PowerShell to install the Hyper-V role, the management tools are not included by default. To install the tools, use the parameter –IncludeManagementTools.  

The Hyper-V technology virtualizes hardware to provide an environment in which you can run multiple operating systems at the same time on one physical computer. Hyper-V enables you to create and manage virtual machines and their resources. Each virtual machine is an isolated, virtualized computer system that can run its own operating system. The operating system that runs within a virtual machine is called a guest operating system.

Practical applications

Hyper-V provides infrastructure so you can virtualize applications and workloads to support a variety of business goals aimed at improving efficiency and reducing costs, such as:

Establish or expand a private cloud environment. Hyper-V can help you move to or expand use of shared resources and adjust utilization as demand changes, to provide more flexible, on-demand IT services.

Increase hardware utilization. By consolidating servers and workloads onto fewer, more powerful physical computers, you can reduce consumption of resources such as power and physical space.

Improve business continuity. Hyper-V can help you minimize the impact of both scheduled and unscheduled downtime of your workloads.

Establish or expand a virtual desktop infrastructure (VDI). A centralized desktop strategy with VDI can help you increase business agility and data security, as well as simplify regulatory compliance and management of the desktop operating system and applications. Deploy Hyper-V and Remote Desktop Virtualization Host (RD Virtualization Host) on the same physical computer to make personal virtual desktops or virtual desktop pools available to your users.

Increase efficiency in development and test activities. You can use virtual machines to reproduce different computing environments without the need for acquiring or maintaining all the hardware you would otherwise need.


New and changed functionality

Hyper-V in Windows Server 2012 and Windows Server 2012 R2 includes improvements in many areas.

Hardware requirements

Hyper-V requires a 64-bit processor that includes the following:

Hardware-assisted virtualization. This is available in processors that include a virtualization option—specifically processors with Intel Virtualization Technology (Intel VT) or AMD Virtualization (AMD-V) technology.

Hardware-enforced Data Execution Prevention (DEP) must be available and enabled. Specifically, you must enable Intel XD bit (execute disable bit) or AMD NX bit (no execute bit).

Software requirements (for supported guest operating systems)

Hyper-V includes a software package for supported guest operating systems that improves integration between the physical computer and the virtual machine. This package is referred to as integration services. In general, you install this package in the guest operating system as a separate procedure after you set up the operating system in the virtual machine. However, some operating systems have the integration systems built-in and do not require a separate installation.

The following topics list the operating systems supported in Windows Server 2012 and Windows Server 2012 R2 for use as guest operating systems in Hyper-V virtual machines, as well as provide information about integration services:

Supported Windows Guest Operating Systems for Hyper-V in Windows Server 2012 R2 and Windows 8.1

Supported Windows Guest Operating Systems for Hyper-V in Windows Server 2012 and Windows 8

For supported Linux distributions as a guest operating systems on Hyper-V, see Linux and FreeBSD Virtual Machines on Hyper-V.
