This article describes the Microsoft System Center Virtual Machine Manager (SCVMM) 2008 R2 issues that are resolved in the hotfix rollup package that was released on June 8, 2010.

List of issues that are fixed

Issue 1 You may experience one of the following symptoms:

• SCVMM Admin Console does not list the GUID partition table (GPT) disks as available storage.
• When you attach a GPT disk to a highly available virtual machine by using Hyper-V Manager or Failover Cluster Management Microsoft Management Console (MMC) snap-in, the SCVMM Admin Console lists the status of the virtual machine as Unsupported Cluster Configuration .

Issue 2 When you manage VMware Virtual Center that has distributed switches, the Virtual Machine Manager service (Vmmservice.exe) crashes.
Additionally, the following events are logged in the VM Manager log:

Log Name: VM Manager
Source: Virtual Machine Manager
Event ID: 19999

Level: Error
Description: System.InvalidCastException: Unable to cast object of type 'Microsoft.VirtualManager.VMWareService.VirtualDeviceBackingInfo' to type 'Microsoft.VirtualManager.VMWareService.VirtualDeviceDeviceBackingInfo'.

Issue 3 Consider the following scenario:

• Quick Storage Migration (QSM) is used to migrate virtual machines (VMs) between cluster shared volumes (CSV).
• After Quick Storage Migration is completed, the Failover Cluster Management MMC snap-in reports that the VM still uses the old CSV volume.

Issue 4 If a VM is configured with 3 virtual processors, the SCVMM Admin Console crashes.
Note To resolve this issue, install this hotfix rollup package and the SCVMM Admin Console rollup 982523. Issue 5 The settings for the virtual network are incorrect after a Refresh-VMHost cmdlet job is completed.
