Agenda

• Introduction to Virtual Server 2005
• The Virtual Environment
• Virtual Server Migration Tool (VSMT)

3
Businesses Need Efficiency

• Server managers need more efficiency
• Application developers need greater flexibility
• Businesses need a solution for legacy systems

4
Virtualization

• Multiple operating systems run simultaneously
• Each virtual machine functions as a computer
• Run testing and production systems side by side
• Use off-the-shelf servers
• Use fewer servers with higher utilization

5
Customers Main Scenarios

• Automation of ApplicationTesting and Development
• Server Consolidation
• Prolong the Lifespan of Windows NT4 Servers and
  Legacy Applications

6
Virtual Server Architecture

7
Standard vs. Enterprise

• There are no differences in features
• The only difference is in the number of
  processors supported
• Standard Edition, can be installed only on
  servers with up to 4 physical processors
• Enterprise Edition, can be installed only on
  servers with up to 32 physical processors

8
Starting and stopping Virtual Server

• Virtual Server 2005 runs as two services
• Virtual Server
• Virtual Machine Helper
• Virtual Server service depends on Helper

9
Caution!!!

• Be sure that you first stop the Virtual Server
  service before shutting down the host operating
  system
• Otherwise, the virtual machines may be powered
  off rather than shut down, which can result in a
  loss of data

What H/W does Virtual Server emulate?

• BIOS
• Floppy Disk Drive
• Serial (COM) Ports Printer (LPT) Ports
• Keyboard and Mouse
• Ethernet Controller
• Processor Memory
• Video card
• IDE/ATAPI Storage
• SCSI Storage

16
Virtual SCSI

• SCSI Controllers, (maximum of 4 per VM)
• Emulates an Adaptec 7870 SCSI controller
• 7 devices per virtual SCSI adapter
• A total storage capacity of 56TB per VM.
• SCSI Disks
• Up to 2TB on each drive
• Much faster than IDE (50-100)

17
Virtual Hard Drives (VHD)

• Various configuration for max. flexibility
• Dynamically expanding
• Fixed-size
• Differencing
• Linked

18

19
Virtual PC vs. Virtual Server

• VPC is a client side virtualization solution
• Virtual Server management is easier
• Use Virtual Server for production

20
Is It Virtual? Is It Real?

SAN Use and High Availability

• A virtual machine can access resources on storage
  area network drives

• Benefits
• A large amount of storage
• Increase data access performance
• Improve recoverability of virtual machines

23
Managing with MOM 2005

• Virtual Server Management Pack for Microsoft
  Operations Manager 2005
• Event and performance management
• Extensible guest-host mapping
• Provides WMI counters on host system
• Event logs also displayed in host event log
• Extensible XML file format
• Virtual machine configuration from external
  management software
• Leverage through COM API for automation

25
Improving Virtual Server Performance

• Increase the acceleration of your graphics
  hardware to full
• Disable all unnecessary pointer options, such as
  pointer trails and shadow cursors
• Optimize system settings for best performance

26
P2V Using VSMT

• Physical to Virtual is a necessity when
  consolidating server into a virtual enjoinment
• VSMT is a free tool that migrates the following
  OSes into Virtual Server
• Windows NT 4.0 Server with SP6a
• Windows 2000 Server with SP4 or later
• Windows 2000 Adv. Server with SP4 or later
• Windows Server 2003, Standard Edition
• Windows Server 2003, Enterprise Edition

27
VSMT Requirements

• An Isolated Network
• A DHCP and ADS infrastructure
• 2 Windows Server 2003 Enterprise edition
• Windows Management Instrumentation
• Download WMI Core for Windows NT

28
Tips and Tricks

• Physical servers with less than 96MB
• FAT file systems
• Hardware limitations

29
6 Steps to Migration
30
Using the Toolkit
? Configure network Virtual Server add-ins for
new Virtual Server
? Run gatherhw.exe
? Power off old hardware (automatic)
? Manually boot to ADS Deployment Agent, causing
image to be captured
Windows NT 4.0 Physical Server
W2K3 Server w/Virtual Server Host VSMT
Task sequence execution
? Move output XML file to ADS controller
? Run generated CreateVM.bat, which executes a
task sequence to create a Virtual Server on the
Virtual Server Host ? Run generated
DeployVM.bat, which executes a task sequence to
deploy the captured image to the new Virtual
Server
? Run VMScript.exe to validate HW config and
generate custom scripts
? Run generated capture.bat
