What is HyperV?


Hyper-V is the hypervisor that is designed by Microsoft to be moved to the Windows Server platform. It is a server virtualization tool with a complete virtualization concept and type 1 hypervisor.

The virtualization platform developed by Microsoft is based on Virtual Server 2005. Later, the first version of the HyperV server appeared from Windows 2008. The version of R2 built into Windows Server roles came with 2008 R2. The launch of the feeling
Windows Server 2012 launches the latest version of HyperV: HyperV v3 or HyperV 2012.

HyperV's operating architecture is a bit special. Officially, HyperV is a complete virtualization system with a Type 1 hypercontroller, but trusting the primary share makes it look like an emulator.

There are two options to deploy HyperV:
Install Windows Server as a role;
Installation of a special edition of Windows Server 2012 HyperV.

Basic diapers


When you first install Windows Server 2012 on the physical server, the host operating system layer replaces the hypervisor. This is the only layer facing the sources. After you set the HyperV role, the HyperV hypervisor switches between the host operating system and hardware. Although the hypervisor controls resources, we see the concept of an operating system host (via the Upper Partition) and the guest operating system (via the Partitions). Unlike Xen Server, where each guest operating system is at the same level as the hypervisor.

As a result, the main section has risen over the Children's Departments. If the Parent Partition encounters an error, the Child Partitions, and so on. How can one associate it with the emulator?

Virtual Machines


Once the basic architecture is placed, you will be able to add VM1. Each VM will run in a standalone environment, in a Child Department. So there are children's departments as well as guest systems.

Each partition can be divided into two points, a "core" side and a "users" side. Includes kernel-side operating systems - Windows Server 2012 for the parent partition and virtualized operating system for the child partitions. The user-side includes the entire application layer, in this case the HyperV administration tools in the main section.

Note that there is a VMBus2 that acts as a BUS between the virtual machines and the resources of the physical server.

Deploy HyperV


It is important to note that HyperV can be deployed in two ways.

HyperV as a Windows Server role


The first option is to enable HyperV as the role of Windows Server. In this case, the administrator hyper is installed after the Windows Server installation. This offers the flexibility to distribute on an existing machine and in production. However, drunk
The choice is less optimized because it is quickly limited.

This type of installation does not conform to In Good Practices, such as Active Directory, especially if there are other roles on that server. In addition, the Windows GUI consumes a significant amount of resources and makes the machine more vulnerable to attacks and difficult to maintain.

HyperV as product

The second preferred option is to consider HyperV as a full-fledged Microsoft product - says Standalone. The DVD is the full version of the Microsoft Windows Server 2012 HyperV server.

This is a minimal installation with roles and prerequisites already deployed in Core mode. However, you can also set up your own installation in Core mode and then configure HyperV.
In this configuration, the server is optimized, secure and easy to maintain. Windows Server consumes fewer resources and leaves more space for virtual machines.

The server will be managed by the Powershell command or by using graphical management tools for the Windows 7, Windows 8 client.
