[Update June 2013]
An official location for the Windows Server 2012 Cluster Updates can be found here:
For Windows Server 2012 clusters it was still very difficult to find a complete list of hotfixes. In the past there were blogs and other locations for Windows Server 2008 R2 Hyper-V and clusters, but not always authorized by Microsoft. This could cause a trust issue for customers who don’t want to rely on some blog.
As MVP’s we have also expressed a wish to see an official list which is maintained by Microsoft. It is great to see our request is honored so quickly and you can now find the Windows Server 2012 Cluster hotfixes
Here is a message from John Marlin, Senior Support Escalation Engineer Microsoft Enterprise Platforms Support:
In a previous blog, it was discussed on where you can get a list of the Failover Clustering and Hyper-V hotfixes for Windows Server 2008 R2.
In this blog, we give the links to newly released hotfixes for Failover Clustering and Hyper-V so you know what hotfixes are out there. There are two Wiki pages that will make life easier for you when looking for hotfixes for Windows Server 2012 Clustering and Hyper-V.
These Wiki pages are updated on a regular basis. You can setup an RSS Subscription to the Wiki page so you can the updated Wiki page in your favorite RSS app or Outlook.
When you configure Live Migration settings on a Windows Server 2012 Hyper-V host then you have two options for authentication of Live Migration sessions:
- Use Credential Security Support Provider (CredSSP)
- Use Kerberos
Kerberos is my recommendation to customers. This is more secure than CredSSP. However the Kerberos option requires constrained delegation. If you do not configure constrained delegation, Live Migration of a virtual machine is not possible and you will receive a message that the source server does not have enough permissions to migrate the virtual machine to another host.
Yesterday I was at a customer location and I would like to configure constrained delegation so that I can use Kerberos as the authentication protocol for Live Migration.
I opened Active Directory Users and Computers and browsed to the computer objects representing the Hyper-V hosts. I went into the properties of the computer object and selected the ‘Delegation’ tab (just like the screenshot below).
When I would add the service Microsoft Virtual System Migration Service this option was not available in the list of services.
So I start a discussion with the guy who had installed the servers and asked him how he did the installation of the Hyper-V role. Then he told me that he had enabled the Hyper-V role while the servers were not joined to Active Directory….. Tadaaa that’s the reason why the service Microsoft Virtual System Migration Service was not available!!
To solve this you had to register the Service Principal Name for this service. To do so you had to open a Command Prompt or a PowerShell prompt and run the following commands:
- setspn -S "Microsoft Virtual System Migration Services\Servername" Servername
- setspn -S "Microsoft Virtual System Migration Services\Servername.fqdn" Servername
After running those commands you will see the ‘Microsoft Virtual System Migration Service” in the list of services that you can add for delegation using Kerberos.
Lesson learned: first join the Hyper-V server to Active Directory and after the server is joined you can enable the Hyper-V role.
My first plan was to write a two part blog article about 5Nine Security Manager. But because of some bugs in the firewall part of this solution I decide to split it up in three parts. In the first part I described a global overview and a look at the installation of 5Nine Security Manager for Windows Server 2012 Hyper-V. Now it’s time to take a look at the antivirus solution.
We will first take a look at the anti-virus/ anti-mallware part of the solution. It sounds great that you didn’t have to install an agent inside a virtual machine and that the Hypervisor wil take care of this. Enabling the antivirus option is very simple:
This week is an important day for Microsoft’s new Hyper-V Extensible Switch in Windows Server 2012. We already know this switch is capable of many new features including capturing, filtering and forwarding extensions from several vendors.
Damian Flynn (fellow author on Microsoft Private Cloud Computing and co-author of Windows Server 2012 Installation and Configuration Guide (appearing very soon!), informed me that major networking player Cisco is about to make a big announcement and that Damian will be co-presenting the announcement with Cisco.
On Wednesday March 6th at 6pm CET, Cisco will unveil its greatly anticipated Distributed Switch solution for Windows Server 2012 and Hyper-V; the Nexus 1000V.
What is the Nexus 1000V?
Cisco Nexus 1000V Series Switches provide a comprehensive and extensible architectural platform for virtual machine (VM) and cloud networking. The switches are designed to accelerate server virtualization and multitenant cloud deployments in a secure and operationally transparent manner. Integrated into the Windows Server 2012 Extensible Switch, and fully compatible with System Center Virtual Machine Manager 2012 SP1,
Please blog, tweet, and pass on the message, to learn about the Nexus 1000v, and how to join the beta program; grabbing the all-important Beta Code!

[UPDATE 28-2-2013] The Dutch System Center User Group Event has been rescheduled for April 18th, 2013. This is in the same week as the Dutch Hyper-v.nu Event. Two great event in one week and both for free, what more can you ask for.
On March the 5th the Dutch System Center User Group Event will take place. The event is hosted by HP in Amstelveen. The presentations are in Dutch and I also have the privilege of presenting a session.
In this session I will explain the new networking features of System Center VMM 2012 SP1 (VM Networks and the Logical Switch).

Today I received news that EMC has released its latest version of the VNX Operating System which covers NAS and Block functionality (VNX OE 32/8) and Maintenance Release 1 (MR1). If you are an EMC customer, this important release is now available for download:
For Windows Server 2012 Hyper-V customers this is especially very good news because VNX now supports SMB 3.0 and ODX (Offloaded Data Transfer), apart from some VAAI performance enhancements which are of course more interesting for the other guys. ODX is very similar to Block XCOPY in vSphere.
EMC is probably the first vendor offering SMB 3.0 support in its storage array. Several vendors are still working on adding SMB 3.0 and ODX support so this is important news for acceptance of Microsoft storage technology and Windows Server 2012 Hyper-V. NetApp SMB 3.0 support is targeted at ONTAP 8.2.
The software can be downloaded from PowerLink or http://support.emc.com.

While cleaning up my mailbox, I found a note to myself dating June 2011 about a few feature requests for the next version of Hyper-V and VMM. While talking to customers throughout the year, I often hear about and collect suggestions and product improvements which I can then pass on to the Hyper-V and System Center Product team. In retrospect most items on my list have become a reality in Windows Server 2012 and much, much more!
Online VHD growth and shrink has not yet been realized (although a 64TB dynamic disk supporting unmap pretty much covers all you can desire).
Perhaps the last item on the list is only partly covered by Hyper-V Replica but needs some additional automation or services to make this a complete Recovery solution that could make it even better than RSM. As we know Microsoft is on the right path and a flood of companies are getting really interested in Windows Server 2012 Hyper-V and System Center 2012 SP1.
Thanks Hyper-V and System Center product teams for listening.

During MVP Summit we spent several great days with Hyper-V Product Manager Ben Armstrong aka @VirtualPCGuy. German fellow Virtual Machine MVP Carsten Rachfahl took the opportunity to interview his ‘rockstar’ at CenturyLink Stadium, home of the SeaHawks football team. Very soon you will notice Ben comes from the other side of this planet, at least when you look at it from our angle: ‘Down Under’.
Ben has delivered many excellent presentations on the Hyper-V hypervisor and related subjects at events like TechEd North America, Europe, Australia and New Zealand:
He has been working on virtualization software for over 10 years now. The last 9 years have been spent working on virtualization as part of the Windows Core Virtualization team. Ben has been maintaining a blog for the last 8 years as Virtual PC Guy. Chances are that if you have a question about virtualization, Ben will know the answer.
