  4. About the Presenter • Consultant and trainer • Virtualization • Security, ISA Server and Forefront • Virtualization background: • Microsoft MVP for Virtual Machine Technology • Whitepaper at microsoft.com: "Virtual PC for Developers" • Manage all Virtual PC / Virtual Server-based labsat TechEd / IT Forum and other international TechEds • Create and optimize many VMs • Create virtualization tools (Virsoft) • Tools to analyse and optimize VMs • Tools to handle VHD-files • Contact: • Beekelaar Consultancyronald@beekelaar.com

  5. Virtualization ToolsVirsoft • Virsoft Lab Menu • Manage, run, log VMs at events + Synchronize VM changes • Virsoft VM Trimmer • Optimize, compact and configure VHDs offline + Compact differencing disks+ Compact folder with multiple VHDs • Virsoft VHD Info • Inspect VHD files + Detect parent-link problems • Virsoft VHD Mount • Provide interface to vhdmount.exe +Mount read-only

  6. Microsoft strategyVision 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

  7. Application Application Application Application Operating System Hardware Type of Virtualization • Application Virtualisation • Microsoft SoftGrid • Desktop/Presentation Virtualisation • Windows Terminal Services • Machine Virtualisation • Virtual Server & Virtual PC • File Virtualization in Vista ?

  11. Application VirtualizationSoftGrid Isolated Virtual Application Model TraditionalLayered Install Model

  12. Application VirtualizationSoftGrid • Applications are virtualized per instance: • Files (including System Files) • Registry • .ini files • Fonts • COM / DCOM objects • Services • Semafores, Mutexes • Name spaces • Applications do not get 'installed' • Applications do not alter the host OS • Note:Tasks process locally on the host computer

  13. Product versions * Currently at end of support lifecycle ** See http://vpc.visualwin.com for a list of 1200+ (!) OS that run in Virtual PC / Virtual Server See KB 867572 for a list of supported OS in Virtual Server 2005 R2

  14. 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

  15. Usage ScenarioProduction 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 • Run on current hardware and current OS • No application updates required • Partition resources • Limit CPU resource per VM

  16. Usage ScenarioBusiness 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 • Isolation / sandboxing • Isolate OS environments for untrusted applications • Prevent malicious code from affecting others

  17. Usage ScenarioDynamic datacenter • Workload mobility • Package up entire OS environment and move to other location • Flexible deployment of workloads

  18. Usage ScenarioDevelopment and test • 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

  19. Usage ScenarioOther server consolidation

  20. Virtualization Support and Licensing • 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 ?

  21. SupportBy Microsoft PSS • Vision in WSS Common Engineering Criteria: • See - www.microsoft.com/windowsserversystem/cer • Limitations ... 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. 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]

  22. Pricing * Virtual Server 2005 Standard Edition is no longer available

  23. Virtual Server 2005 R2 FreeWhy 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

  24. LicensingWindows 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 • See - www.microsoft.com/licensing/resources/volbrief.mspx
