Introduction |
Hyper-V is the next level of virtualization, with Windows Server 2008 you no
longer need to deploy an application such as Virtual Server 2005 or Virtual PC
or other virtualization technology in order to build your virtual machines.
Hyper-V is one of the new roles available with Windows Server 2008 where you can
install it and then start creating your virtual machines, take different
snapshots for every virtual machine and much more. You
can use a virtualized computing environment to improve the efficiency of your
computing resources by utilizing more of your hardware resources.

In this two parts article, I will show you how to install the Hyper-V role
and then in part two I will install Windows Server 2008 as a virtual machine
with Hyper-V.
Hyper-V requires specific hardware. You will need the following:
- An x64-based processor. Hyper-V will be available only in the x64-based
versions of Windows Server 2008, the x64-based versions of
Windows Server 2008 Standard, Windows Server 2008 Enterprise, and Windows
Server 2008 Datacenter.
- Hardware-assisted virtualization. This is available in processors that
include a virtualization option; specifically, Intel VT or AMD
Virtualization
- Hardware Data Execution Protection (DEP) must be available and be
enabled. Specifically, you must enable Intel XD bit (execute disable bit) or
AMD NX bit (no execute bit).
Before installing Hyper-V, let me show you a table that will summaries the
differences between Hyper-V and Virtual Server 2005 R2

Perform the following steps to install Hyper-V
- Click Start > Server Manager

- From the left side panel inside Server Manager, click on
Roles

- The Roles page will open, where it shows you the number of roles
you have installed on your machine, Click on Add Roles

- The Add Roles Wizard page will open, click on
Next

- From the list of roles available, select Hyper-V > Click
Next

- The Introduction to Hyper-V page will open, take a few moments to read
it , and then click on Next

- The Create Virtual Networks page will open, You can create many virtual
networks on your virtualization server to provide a variety of
communications channels. For example, you can create networks to provide the
following:
- Communications between virtual machines only.
- Communications between the virtualization server and virtual machines.
- Communications between a virtual machine and a physical network by creating
an association to a physical network adapter on the virtualization server.
You can either select the Network Adapter that will be attached with the
Virtual machines now, or you can do this later using the Virtual Network
Manager , Click Next
You use the Virtual Network Manager to add, remove, and modify the virtual
networks. The Virtual Network Manager is available from Hyper-V Manager.
As a best practice, it is recommended that you have at least two network
adapters on your machine, so that one of the Network adapters is used by the
host, and the other network adapter is used by the guest virtual machines

- On the Confirm Installation Selection page, click
Install

Installation will be initialized and once completed, you will be informed
that a restart is required, click Close


- You will be asked if you want to restart your server now, click
Yes

- Once you log on again to your machine, the
installation will resume, and then on the
installation result page, you will get notified if
the installation encountered any errors or it was
completed successfully > Click Close


Summary
In part 1 of this two parts article, I showed you what are the differences
between Hyper-V and Virtual Server 2005, also what are the requirement for
Hyper-V, and then finally installed Hyper-V on our Windows Server 2008. In part
2 of this article, I will install Windows Server 2008 as a virtual machine using
Hyper-V
