Microsoft strategy
Vision of virtualization
•
IT organization benefit when workloads are decoupled from
hardware
• Increased availability, manageability
• Long term, workloads will be increasingly dynamic
• Virtualization is a key enabling technology to achieve this

Type of Virtualization
•
•
Application Virtualisation
• Microsoft SoftGrid
Desktop/Presentation Virtualisation
• Windows Terminal Services
•
Machine Virtualisation
• Virtual Server & Virtual PC
•

Usage Scenarios for Virtualization
 Production server consolidation
• Consolidate low-utilization workloads
• Legacy OS (NT4) and application re-hosting
• Resource partitioning (limit resources per VM)
 Business continuity management
• Workload deployment and provisioning
• OS and application patching (swap VMs)
• Isolation / sandboxing
 Dynamic data center
• Workload mobility
 Development and test
• Rapid provisioning of multiple virtual machines
• Undo-disk and save state helpful
14
Usage Scenario
Production server consolidation
•
Consolidate workloads
• Infrastructure applications
• Branch office and datacenter workloads
• Low-utilization workloads
• Efficient use of available hardware resources
•
Re-host legacy OS and applications
• NT4 guest applications on Win2003 host
•
•
•
15
Run on current hardware and current OS
No application updates required
Partition resources
• Limit CPU resource per VM
Usage Scenario
Business continuity management
•
Workload deployment
• Quickly switch pre-configured VM (vhd-files)
• For disaster recovery
• Eliminate unscheduled downtime
• OS and application patching
• Deploy and test patches off-production, and swap
• Eliminate scheduled downtime
•
16
Isolation / sandboxing
• Isolate OS environments for untrusted applications
• Prevent malicious code from affecting others
Usage Scenario
Dynamic datacenter
•
17
Workload mobility
• Package up entire OS environment and move to other location
• Flexible deployment of workloads
Usage Scenario
Development and test
18
•
Rapid provisioning of virtual machines
• Provide multiple VMs for testing quickly
• Use save state to start up quickly
•
Create arbitrary test scenarios
• Recreate reported issues
• Avoid use of production network
• Use undo-disk to rollback to known state
•
Wider test range for niche scenarios
• Provision multiple VMs with variations
• Use difference-disks for easy provisioning
Usage Scenario

Virtualization Support and Licensing
20
•
Support (two meanings)
• Supported by Microsoft Product Support
• Technical possible with the product
•
Needed licenses
• On host - host OS and Virtual Server ?
• In guests - guest OS and applications ?
Support
By Microsoft PSS
•
Vision in WSS Common Engineering Criteria:
... all server products will support Microsoft Virtual Server 2005.
Each product must be capable of running from within a virtual instance.
Exemptions will be granted if:
• The product requires hardware that is not currently supported in the VM environment.
• Core product scenarios fail because of virtualization performance or scaling issues.
• See - www.microsoft.com/windowsserversystem/cer
• Limitations
Exchange Server 2003 - Only on Virtual Server 2005 R2 or later (KB 320220)
Certificate Server
- Only with Win2003 SP1 or later guest and host (KB 897614)
ISA Server 2006
- Is supported, but not recommended (KB 897613)
KB 897613 - Microsoft supports Windows Server System software running within a Microsoft
Virtual Server environment subject to the Microsoft Support Lifecycle policy ...
KB 897614 - The following Windows Server System software is not supported within a
Microsoft Virtual Server environment: Speech Server, ISA Server 2000/2004, MIIS 2003,
Sharepoint Portal Server.
KB 897615 - For Microsoft customers who do not have a Premier-level support agreement,
Microsoft will require the issue to be reproduced independently from the non-Microsoft
hardware virtualization software.

KB 917437 - Microsoft support for Linux guest operating systems is currently limited to
the following list of qualified and tested operating systems: [9 Linux distributions]

Why would Microsoft do that?
•
Reasons:
• Customer satisfaction
• Increase interest in Win2003 R2 EE
•
1 license = 4 VMs + host
• Accelerate proof-of-concept test efforts
• Rapidly deploy workloads (AD / SQL / BizTalk, etc)
• Ease migration to Longhorn virtualization
23
Licensing
Windows server licenses
•
Licensing changes for server products
• Virtualization friendly (after 1-Dec-2005)
 Only count licenses for running VMs
 For per-processor licenses, only count virtual CPUs in VM
 Single Win2003 R2 EE license:
•
1 host + 4x Win2003 R2 EE in guest
• Virtualization unlimited (after 1-Oct-2006)
 Single Win2003 R2 Datacenter license:
1 host + unlimited Win2003 R2 (any) guests
