Hyper -V is a hypervisor - based virtualization technology from Microsoft for computers running x64 -compatible x86 processor. Hyper-V is available both as an integral part of server operating systems (eg Windows Server 2012 Datacenter and Standard) and in the form of standalone version ( for example, Microsoft Hyper- V Server 2012). In addition, the Pro and Enterprise editions of the client operating system, Windows 8 include the Hyper- V technology. In all these products, Hyper-V is either by default or optionally installable in case of need as a component. The standalone version Microsoft Hyper- V Server 2012 is available for free and has the same features with the exception of the optional GUI.


  • Complete isolation of the individual systems
  • Security functions of the hardware level can be used, for example, Data Execution Prevention (DEP )
  • Hyper- V supports Network Address Translation (NAT) and Network Access Protection ( NAP)
  • Management via the Microsoft Management Console ( MMC)
  • In cluster mode, the Hyper- V can make so-called live migrations. This allows to move virtual machines are running.
  • As Rootsysteme Windows Server 2008, Windows Server 2008 R2, Windows 8, Windows 8.1, Windows Server 2012 and Windows Server 2012 R2 can be used

Up to 64 processors and 1TB of RAM is assigned to a child system.


The hypervisor is available in two versions: a server role or operating system feature (eg, in Windows Server 2012 or Windows 8 ) and as a stand-alone product (such as Microsoft Hyper- V Server 2012). The latter version is free, but does not include, if necessary, licenses required for the child system. In addition, this version is only used in the core operation, which is simplified by the use of PowerShell ( PsHyper - V). These are the only restrictions on the paid version.

Areas of application

Hyper-V is effectively used in many scenarios - both for virtualizing whole data center, as well as from smaller environments. Since the penultimate version of the complete network configuration without 3rd party tools (such as NIC teaming and VLAN configuration ) can be carried out beyond, to Hyper-V provides, inter alia, the virtualization of entire switches ( vSwitch ). For extended functionality provides System Center Virtual Machine Manager ( SCVMM ), which for the management of VMs and hosts, among others can be used based on Hyper-V.

With version 8 available in Windows Hyper- V, however, can also be used for client virtualization. However, it should be noted that the root operating system is running after enabling Hyper- V itself in a privileged machine and there may be problems eg with latency-sensitive real-time applications. Therefore, it is also wrong for Hyper- V to talk about the root OS from a " host OS" and the child systems from a " Guest OS", since both ( root OS and child systems ) are carried out on one level.

Supported guest operating systems

Microsoft only supports some versions of Windows also officially the Linux distributions SUSE and OpenSUSE.

  • Red Hat Enterprise Linux 5.2 / 5.3 / 5.4 / 5.5 / 5.6
  • SUSE Linux Enterprise Server 10 SP4
  • SUSE Linux Enterprise Server 11 SP1
  • OpenSUSE 12.3

With Windows 8 XP and older versions are no longer supported in virtual mode. A list of all supported operating systems are available at Microsoft TechNet. Since the Linux kernel version 2.6.32, the Hyper- V Integration Components are an integral part and can be easily activated in other Linux distributions. From CentOS 6.4 drivers for Hyper- V are directly included in the packages of the distribution.
