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:

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.
