Microsoft released yesterday another Update Rollup for System Center 2012 R2 Virtual Machine Manager which includes updates both for the VMM server and for the Administrator console. Some of issues that are fixed:
- When you try to run a large scale deployment of a service instance, VMM Placement may store many VMs unevenly on a single host.
- Virtual Machine Manager (VMM) Administrator Console crashes on all Windows 10-based client computers that have the Anniversary Update installed.
- VMM removes cluster disks from a virtual machine (VM) resource group if they are accessed as mount points.
- The CPU Average and Memory values that are shown in the VMM Console are not calculated based on the average of the last 10 minutes. Instead, VMM just considers the latest value.
These updates have to be manually downloaded from the Microsoft Download Center and they are not available through Microsoft Update.
