Hi All,

A new VMM 2008 R2 rollup is now published and available thru Microsoft Update.

Description of the System Center Virtual Machine Manager 2008 R2 hotfix rollup package: September 14, 2010

http://support.microsoft.com/kb/2308590

in this rollup:

Missing VM caused by a crash of a Hyper-V node and out-of-band failover

Cannot create VM on cluster shared volume if the host is configured to boot from VHD

Changing PRO Settings on a HostGroup with External MP imported causes VMMserver to crash

List of issues that are resolved

Issue 1

Duplicate virtual machines (VMs) may appear in the SCVMM Administrator Console window after a Hyper-V VM in a cluster fails over to another cluster node. Additionally, the status for one of the duplicate VMs is set to Missing. If you try to remove the missing VM from the SCVMM Administrator Console window, the VM is not removed.

Issue 2

Consider the following scenario:

  • You install the Hyper-V role on a computer that is running Windows Server 2008 R2.
  • You configure the computer to start from a virtual hard disk.
  • The computer is part of a Hyper-V failover cluster. The cluster is configured to use cluster shared volumes.
  • You try to create a VM on a cluster shared volume by using SCVMM 2008 R2.

In this scenario, the operation fails together with the 2912 (0x8004232C) error code.

Issue 3

The Virtual Machine Manager service (Vmmservice.exe) crashes if the following conditions are true:

  • System Center Operations Manager 2007 integration is enabled.
  • A Performance and Resource Optimization (PRO) feature-enabled management pack is imported into Operations Manager.
  • The PRO settings for a host group are changed on the SCVMM server.
