This document summarizes new features in Hyper-V 2008 R2 and VMM 2008 R2, including support for more virtual processors and VMs per host, clustered shared volumes for easier VM migration, live migration capabilities, core parking for improved resource utilization, second level address translation for performance gains, and the virtual machine queue for network improvements. It also discusses upgrades to VMM 2008 R2, including support for live migration and improved storage and network functionality.

2. Enable audio in Windows and the client

4. What’s New with Hyper-V 2008 R2 and VMM 2008 R2 Aidan Finn BSc, MCSE, MVP http://joeelway.spaces.live.com

6. Cluster Shared Volumes

7. Live Migration

8. Core Parking

9. Second Level Address Translation

10. Virtual Machine Queue

11. Native VHD

13. Specialised in servers and systems management

14. MVP:

15. 2008: Configuration Manager

16. 2009: Virtualisation – Systems Management

17. Blog: http://joeelway.spaces.live.com

19. 512 virtual processors (8 VP’s per LP)

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

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

45. Live Migration

46. Live Migration Create VM on target server Copy memory pages from the source to the target via Ethernet Final state transfer Pause virtual machine Move storage connectivity from source host to target host via Ethernet Run new VM on target; Delete VM on source Host 1 Host 2 Blue = Storage Purple = Networking Shared Storage

47. Live Migration State Transfer Memory Configuration Configuration State State Server 1 Server 2

49. The same family of processor – no mixing of Intel and AMD

52. Hypervisor maps processor usage data into the parent

53. Updates every 100ms

54. Parent tells hypervisor which cores to park

55. Hypervisor lets processors finish work, but stops including them in scheduling decisions

57. Second Level Address Translation

58. VM Memory Management Guest Virtual Address Guest Virtual Address Guest OS defines GVA-to-GPA mappings Shadow page tables combine these mappings because the processor knows how to perform only one level of translation Guest Physical Address Hypervisor defines GPA-to-SPA mappings System Physical Address System Physical Address Hyper-V R2 Hyper-V

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

70. Virtual Machine Queue (VMQ) Parent Partition VM1 VM2 Virtual Machine Switch Ethernet TCP/IP TCP/IP Routing VLAN Filtering Data Copy Port 1 Port 2 VM NIC 1 VM NIC 2 Miniport Driver NIC VM BUS

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

77. Concurrent receive processing for multiple VMs

78. Avoiding copy from NIC receive buffers to VM address space

81. VHD – Virtual Hard Disk used by virtualisation products and Windows backups

83. Boot from a VHD file

84. W2008 R2 WDS able to deploy VHD files

87. Basic management using Hyper-V and Failover Clustering MMC’s

88. Advanced virtualisation management using System Center Virtual Machine Manager

89. VMM 2008 integrates with OpsMgr 2007

90. System Center Enterprise CAL: includes 4 VM’s on the host

92. Easier cluster management

93. Hardware templates

94. Library for VHD’s, PowerShell scripts, ISO

95. Self Service web console

96. Can manage Virtual Server 2005, ESX and many Virtual Center installations

97. Integrates with OpsMgr 2007 SP1

100. Integration with OpsMgr 2007 R2

101. Support for Live Migration

102. Allows many VM’s per LUN for CSV

103. Storage Quick Migration

104. SAN enhancements, e.g. cluster-cluster migration, rapid provisioning & snapshots

105. Network enhancements

106. Maintenance mode
