What this Session is About Tips / Tricks / Best Practices / Lessons Learned from Virtual machine conversions Practical guidance for creating Dynamic Datacenter Management of Heterogeneous virtualization platform What this Session is NOT About Intro to Hyper-V R2 or SCVMM 2008 R2 Basic installation and configuration
Challenges: Underutilized hardware Excessive power consumption Expensive space across datacenter and branch offices Challenges: Underutilized hardware Excessive power consumption Expensive space across datacenter and branch offices Server Consolidation The fastest way to reduce costs Server Utilization
Datacenter Evolution Traditional Datacenter Virtualized Datacenter On premises dynamic Datacenter - Cloud Off premises dynamic Datacenter - Cloud
Dynamic Datacenter Physical to Virtual Management with System Center Vision of Datacenter Management and the path to Dynamic IT Why Microsoft Virtualization –Unique value of Physical and Virtual Management from one common platform –Application (or in-guest) insight –Dynamic responses to changing workloads Coexistence
Microsoft Delivers Dynamic IT Through Datacenter Systems Management Desktop Data Center
Consolidate Servers Through Simplified Virtualization And Management 9% utilization 6% utilization 50% utilization 10% utilization Number of physical servers Power usage Floor space 11% utilization 14% utilization Server utilization
Conversion Overview Physical to Virtual (P2V) –Convert a physical server to a virtual machine Virtual to Virtual (V2V) –Convert an existing virtual machine from one technology to another Virtual to Physical (V2P) –Convert a virtual machine into a physical server Both P2V and V2V are supported scenarios using System Center VMM 2008 R2 3 rd parties have V2P solutions
P2V: Source Server Conversion Requirements Minimum of 512 MB RAM Must be in a workgroup environment, in the same domain as the VMM server, or a member of a domain that has a full two-way trust with the domain of the VMM server Should contain one of the following supported operating systems: –Windows Server 2008 R2 –Windows Server 2008 (32/64-bit) –Windows Server 2003 (32/64-bit) SP2 –Windows 2000 Server SP4 Rollup Update 1 (Offline P2V only) –Windows 2000 Advanced Server SP4 RU1 (Offline P2V only) –Windows XP Professional (32/64-bit) SP2 or later –Windows Vista SP1 or later (32/64-bit)
P2V: Target VM Conversion Limitations Target virtual machine hardware cannot exceed listed items, or conversion will fail –Maximum of 64 GB RAM –Maximum of 4 processor cores –Maximum of 12 network interfaces –Maximum of 2040 GB disk if using VHD –Maximum of 256 TB per disk if using pass- through disks –Maximum total storage of 517 TB per virtual machine using VHDs –Maximum total storage of 66560 TB per virtual machine using pass-through disks
P2V: Conversion Methods Online P2V conversion - Performing a P2V conversion of a running physical server –No downtime required –Requires source server running a Windows Operating system with Volume Shadow Copy Services (VSS) –Windows 2000 Server does not support Online P2V –Copies the VSS snapshot over the network Offline P2V conversion – Performing a P2V conversion of a powered down physical server –Downtime required –Physical server is booted into WinPE running P2V agent –Disk is copied at byte level across the network to a VHD at the target location –VSS is not utilized
P2V: Conversion Considerations Server identity is maintained during conversion –Having both machines running on the same network will result in conflicts Online P2V conversion –VSS snapshot is a point in time If data is changing on the server during conversion, the VM will not have them –Physical server should go offline once the conversion is complete and you are ready to keep the virtual machine online Only one can be authoritative –Physical server should be isolated or wiped to prevent collision impacts if accidentally brought back on the production network –Some server roles should not be converted using online approach due to transactional nature Domain Controllers Offline P2V conversion –Can be used with any supported OS –Older OS might require additional software to be installed prior to conversion Windows Installer 3.1 Patches or drivers for the WinPE version are required
P2V: Conversion Best Practices Run Chkdsk and defrag the hard disks of the source server before conversion –Bad sectors won’t get transferred Use fast network cards to reduce the time to complete a conversion Perform the conversion to a staging server to reduce impact to production Hyper-V servers SAN attached data volumes –If the target VM can be connected to the same SAN, can use pass-through for data disks and reattach LUNS versus converting to VHDs iSCSI attached data volumes –If the source server has iSCSI attached data volumes, they can migrate with no changes Develop a quick rollback process for a failed P2V conversion
System Center Virtual Machine Manager 2008 R2 Maximize Resources Centralized virtual machine deployment and management for Hyper-V and VMware ESX servers Intelligent placement of Virtual Machines Fast and reliable P2V and V2V conversion Integrated Performance and Resource Optimization (PRO) of VMs A centralized, heterogeneous management solution for the virtual datacenter Increase Agility Rapid provisioning of new and virtual machines with templates Centralized library of infrastructure components Leverage and extend existing storage infrastructure and clusters Leverage Skills Familiar interface Monitor physical and virtual machines from one console Fully scriptable using Windows PowerShell
System Center Virtual Machine Manager 2008 R2 SCVMM 2008 R2 Features Hypervisor Management - Hyper-V, VMware Cluster Integration Host Configuration Intelligent Placement Library Management Deployment and Storage Virtual Machine Creation/Provisioning Monitoring and Reporting Conversions: P2V and V2V Automation with PowerShell Delegation and Self Service Performance and Resource Optimization Management of Windows Server 2008 R2 and Microsoft Hyper-V R2 Multiple Virtual Machines Per LUN Live Migration Cluster Shared Volumes Storage Migration Maintenance Mode Hot Add of Storage Rapid Provisioning
Managing P2V and V2V conversions with SCVMM Intuitive and easy to use tools provide: Core feature of VMM, no additional infrastructure or costs per conversion Wizard based experience Reconfigure storage, memory, CPU, etc. Efficient disk copy Preserves network settings and MAC addresses Automatable through PowerShell Supported platforms: Online - Windows XP, Windows Server 2003, Windows Vista, and Windows Server 2008, Windows Server 2008 R2 and Windows 7 Offline - Windows 2000 Server
Performing a P2V Conversion using SCVMM VMM Agent is installed on source computer. Inventory of source computer is conducted and hardware configuration returned to VMM Server. VMM transfers the volume data using BITS. Offline P2V conversion reboots the source computer into Windows PE at this point. The VHD is “fixed up” i.e. Hyper-V components are added to the installation and configured. Other hardware specific drivers and software will need to be removed manually and the completion of the conversion process. Finally the VM is created and appears in the SCVMM console. The VM can optionally be running at this point and the source computer shutdown completely.
Before starting P2V Conversion… Windows 2003 SP2 P2V Conversion You must copy sp2.cab from the service pack media (or dllcache) on the source server to “C:\Program Files\Microsoft System Center Virtual Machine Manager 2008\Patch Import” folder run the “Add-Patch” cmdlet to add the required files to the Virtual Machine Manager patch cache Windows 2000 P2V Conversion When performing a P2V conversion of Windows 2000 Server or Advanced Server, the following components must be installed on the source computer. Service Pack 4 Post Service Pack 4 update – KB891861-v2 Windows Installer 3.1 Redistributable (v2) Microsoft Visual C++ 2005 Redistributable Package.NET Framework 2.0 BITS 2.0 Update KB842773

Performing Virtual to Virtual Conversions (V2V) The source virtual machine can be in the library, in a network share or managed by a VMware ESX Server and must have one of the following operating systems installed: Windows Server 2008 (32-bit) Windows Server 2008 (64-bit) Windows 2000 Server SP4 or later Windows 2000 Advanced Server SP4 or later Windows XP Professional (32-bit) SP2 or later Windows XP Professional (64-bit) SP2 or later Windows Vista Service Pack 1 (32-bit) Windows Vista SP1 or later (64-bit) Before you convert a VMware virtual machine to a Hyper-V virtual machine, you must uninstall VMware Tools on the guest operating system of the virtual machine.
