Microsoft Virtualization Technologies

Server Virtualization

Desktop Virtualization

Presentation Virtualization

Application Virtualization

User State Virtualization

Server Virtualization

Server virtualization enables multiple virtual machines to run on one physical host

Server virtualization enables multiple virtual machines to run on one physical host

Benefits:• Server consolidation

• Service or application isolation

• Simplified server deployment Increased service and application availability

• Multiple operating systems can run on one consistent platform

Desktop Virtualization

Desktop virtualization provides options for virtualizing client operating systems

Desktop virtualization provides options for virtualizing client operating systems

Desktop virtualization option

Description

Client-Hosted Virtual machines run on the user desktop to provide an alternate computing environment

Virtual Desktop Infrastructure

Client virtual machines are hosted in the data center and accessed through remote desktop

Microsoft Enterprise Desktop Virtualization

Provides the tools to build and deploy client virtual machines to user desktops

Presentation Virtualization

• Presentation virtualization runs applications on centralized servers

• Windows Server 2008 R2 Remote Desktop Services replaces Terminal Services

• Presentation virtualization runs applications on centralized servers

• Windows Server 2008 R2 Remote Desktop Services replaces Terminal Services

Benefits include:

• Centralized data

• Simplified application management

• Integration with application virtualization Potentially improved performance

Application Virtualization

Application virtualization provides virtual environments for applications running on user desktops

Application virtualization provides virtual environments for applications running on user desktops

Benefits include:

• Enables potentially incompatible applications to run on one computer

• Application deployment is easier

• Virtual application use is transparent to users

Lesson 2: Implementing the Hyper-V Role

• What Is Hyper-V?

• Hardware Requirements for Hyper-V

• Virtual Hard Disks

• Virtual Networks

• Virtual Machines

• Demonstration: How to Configure a Virtual Machine

• What Is VMM 2008 R2?

What Is Hyper-V?

Next generation hypervisor-based virtualization technology

Allows efficient running of multiple and different operating systems in parallel

Allows full leveraging of the power of x64 computing

Hardware Requirements for Hyper-V

Hyper-V does not support Itanium (IA-64) processorsHyper-V does not support Itanium (IA-64) processors

x64 server with hardware-assisted virtualization is available on:

Hardware enabled Data Execution Prevention required:

• AMD AMD-V or Intel VT

• AMD (NX no execute bit)

• Intel (XD execute disable)

Virtual Hard Disks

Dynamically expanding virtual hard disk:

Fixed-Size virtual hard disk:

Benefit:• Efficient use of storage

Drawbacks:• Deferred storage allocation• Fragmentation

Benefit:• Upfront storage resource allocation

Drawback:• Portability

Differencing virtual hard disks:

Benefits:• Isolate changes • Can be used for standardized base images

Drawbacks:• Dynamic size• Cannot be compacted• Increased overhead

Virtual Networks

Virtual Networks

Types of virtualnetworks

Virtual Machines

Virtual machine components include:

• Virtual processors

• Memory

• Network Adapters

• Virtual Disks

Virtual machines can run:

• Windows Server 2008 and Windows Server 2008 R2

• Windows Server 2003 SP2 and Windows Server 2003 R2 SP2

• Windows 2000 Server, SP4

• Redhat and Suse Linux

• Windows 7, Windows Vista and Windows XP SP2 or later

Demonstration: How to Configure a Virtual Machine

• In this demonstration, you will see how to create and configure a virtual machine in Hyper-V Console

What Is VMM 2008 R2?

VMM is used to:

VMM 2008 R2 provides centralized administration and management of your virtual environment

VMM 2008 R2 provides centralized administration and management of your virtual environment

• Manage Hyper-V hosts

• Manage Virtual Server 2005 R2 hosts

• Manage VMware hosts

• Manage and deploy virtual machines

• P2V and V2V conversions

Lab: Implementing Virtualization

• Exercise 1: Creating the VHDs

• Exercise 2: Creating New Virtual Machines

• Exercise 3: Modifying Virtual Machine Settings

• Exercise 4: Creating and Applying Virtual Machine Snapshots

Estimated time: 30 minutes

Logon information

Lab Scenario

• Contoso, Ltd. has decided to introduce virtualization into their information technology (IT) environment because they wish to reduce their hardware and power expenditures for the data center. The company has started deploying Hyper-V host computers running on Windows Server 2008 R2. You now need to create several virtual machines on the host computers.

Lab Review

• In the lab, you created a differencing VHD and a dynamically expanding VHD. What other types of virtual hard disk drive can you create?

• In the lab, you configured the virtual machines to use the External network. If you had selected an Internal network, with which components could the virtual machines communicate?
