As mentioned on the last post, We have Rollup 3 for System Center 2012 SP1.


Lot many issues got fixed specific to SCVMM. Here is the list of issues which got fixed with this rollup.

Issue 18

The VMM server might crash when you create a virtual machine template from a virtual machine that has a previous failed task checkpoint data.

Issue 19

Logical unit numbers (LUNs) for EMC storage cannot be assigned to a cluster in VMM.

Issue 22

Network Virtualization with SCVMM 2012 Sp1 – Some key points before start

I was running around this topic for the last few months. Once we had Windows 2012 HyperV Clusters, the next target was to try out network virtualization. Unfortunately, SCVMM 2012 Sp1 was not ready at that time. Recently, we got that. We did attempted and few points which I understood now is

  • For enabling communication between a Network Virtualized subnet and a non network virtualized subnet, A Virtualization Gateway needs to be in the middle
  • Virtualization Gateway devices are still under development and major network vendors are getting ready for release
  • Microsoft is coming up with Software-based NV Gateway which will be fully integrated with SCVMM
  • F5 is also coming with Network Virtualization gateway – but time lines are not confirmed

To my knowledge, the whole stuff is amazing but its complicated. Lack of documentation and information makes it complicated and I expect to see more official documentation coming up for NV in the coming days.

If you have any further information to add on, Please comment. I am open for a discussion.



SCVMM 2012 Sp1 – Building a priviate cloud

I am very excited to let you all know that I am trying out a private cloud with SCVMM 2012 Sp1. Its almost three weeks I am playing around SCVMM 2012 Sp1. Still trying to understand the concepts and features. In the initial phase, I was in the assumption that configuration is something which I can do easily. Unfortunately, Fabric configuration made me into panic mode having sequence of issues. At-last, I landed safely by fixing all issues.

Another important note is on Roll-up 1. As you are aware, System Center 2012 Sp1 got a new Roll-up1 which got released on Jan 9th 2013. This rollup is intented to fix the below issues. I am yet to apply this roll-up, but scheduled for this weekend.


Virtual Machine Manager (KB2792925 – Console; KB2792926 – VMM Server)

Issue 1

When a logical unit number (LUN) is unmasked on an iSCSI array, the VMM service may crash.

Issue 2

When a node is put in maintenance mode, virtual machines in the cluster change to a status of “Unsupported Cluster Configuration.”

Issue 3

When an add-in that uses multiple DLL files is imported into the VMM console, the add-in is not imported. Additionally, you receive the following error message:

Add-in cannot be installed

Issue 4

When an add-in is imported into the VMM console on a server that is running Windows Server 2008 R2, the add-in is not imported.

Issue 5

When an add-in is imported into the VMM console, the console may crash.
