- 12. Virtual Machine Manager 2008 R2About Aidan FinnWorking with large and complex IT since 1996
- 13. Specialised in servers and systems management
- 14. MVP:
- 16. 2009: Virtualisation – Systems Management
- 18. Windows User Group: http://ws-ugi-spaces.live.comVersionsMax per host support increased:64 logical processors (cores)
- 19. 512 virtual processors (8 VP’s per LP)
- 21. Failover Clustering Pre R2Uses Windows 2008 Failover Clustering for hardware fault tolerance
- 22. Easier than ever – honestly!
- 23. Virtual machine treated as cluster resource
- 24. Each VM should (not must) be on a dedicated LUN *
- 25. Quick Migration, not Live Migration (aka VMotion)* Mandatory for VMM 2008
- 27. VM saves its state
- 28. Disk fails over to destination host
- 29. VM restores its saved state
- 30. 1GB RAM VM Takes 8 seconds on 4GB Fibre Channel SAN with 15K SCSI disks, e.g HP EVA SAN
- 31. Supported with Fibre Channel and iSCSI
- 32. Test labs will work with W2008 file shares
- 33. Live Migration coming in W2008 R2!Cluster Shared Volumes
- 34. Clustered Shared VolumesClustered Shared Volumes (CSV) implements hybrid sharing for LUNs
- 35. One node owns the storage namespace (e.g. directory structure) and metadata
- 36. Other nodes can own the storage backing an individual file’s data (e.g. VHD)
- 37. Benefits of CSV:
- 38. Can store all VM VHDs on one LUN
- 39. High-performance access to VHDs from owning nodes
- 40. All nodes have read/write access to file data
- 41. Seamless VM movement between nodes
- 42. Any node can read from VHD, so no need to change LUN ownership
- 43. Seamless LUN ownership transition
- 44. Persistent handles allow cluster to move LUN without interruption to VM operationCluster Shared VolumesAll servers “see” the same storage
- 45. Live Migration

- 47. Live Migration State TransferMemoryConfigurationConfigurationStateStateServer 1Server 2
- 48. RequirementsGood networking between hosts
- 49. The same family of processor – no mixing of Intel and AMD
- 50. You can mix generations of one family by disabling features via one tick box. Core Parking
- 51. Core ParkingKernel in parent performs core-parking control
- 52. Hypervisor maps processor usage data into the parent
- 54. Parent tells hypervisor which cores to park
- 55. Hypervisor lets processors finish work, but stops including them in scheduling decisions
- 56. Will use them if necessary to meet child CPU guaranteesCore Parking OperationCore 0Core 1Core 0Core 1Core 1Core 0Core 0Core 1Socket 0Socket 1Workload
- 57. Second Level Address Translation
- 58. VM Memory ManagementGuest Virtual AddressGuest Virtual AddressGuest OS defines GVA-to-GPA mappingsShadow page tables combine these mappings because the processor knows how to perform only one level of translationGuest Physical AddressHypervisor defines GPA-to-SPA mappingsSystem Physical AddressSystem Physical AddressHyper-V R2Hyper-V
- 59. Second Level Address Translation(SLAT)Goes by several names
- 60. Intel: Extended Page Tables (EPT)
- 61. AMD: Nested Page Tables (NPT)/Rapid Virtualization Indexing (RVI)
- 62. Processor provides two levels of translation
- 63. Walks the guest OS page tables directly
- 64. No need to maintain Shadow Page Table
- 65. No hypervisor code for demand-fill or flush operations
- 66. Resource savings
- 67. Hypervisor CPU time drops from 10% to 2%
- 68. Roughly 1MB of memory saved per VM
- 69. Benefits Large Memory WorkloadsVirtual Machine Queue

- 71. BottlenecksCopying data from child partition address space to the parent partition address space
- 72. MAC address lookup and VLAN ID filtering
- 73. Parent/child context switch overhead
- 74. Simulating task offload in software for VM to VM traffic

- 76. Performance ImprovementsApplying VLAN filtering in hardware
- 77. Concurrent receive processing for multiple VMs
- 78. Avoiding copy from NIC receive buffers to VM address space
- 79. Using switch on the NIC to do route lookup on transmitNative VHD
- 80. Image TypesWIM – Used by Windows Installer (Panther), WDS and ConfigMgr
- 81. VHD – Virtual Hard Disk used by virtualisation products and Windows backups
