Windows Server 2012 Hyper-V Installation and Configuration Book

If you are in some way dealing with Hyper-V in Windows Server 2008 R2 and probably now exploring Windows Server 2012 Hyper-V, you are by no means able to avoid the blogs, whitepapers, books and tweets written by Aidan Finn. In 2010 Aidan asked me to be a technical editor for his Mastering Hyper-V Deployment which I gladly accepted. It was a great step-by-step for implementing Hyper-V R2 and several of the important System Center components. The book was co-authored by Patrick Lownds, Hyper-V MVP and datacenter expert working for HP in London.

About a year later, Aidan approached me again asking if I would be willing to contribute to another book called Microsoft Private Cloud Computing and I did not think about refusing (or should I have). It was my first experience as an author and I wrote up the Fabric chapters of VMM 2012. Aidan laid a nice foundation with his lucid Cloud introduction chapters, Patrick focused on the service management functionality and the VMM Library while Cloud and Datacenter MVP, Damian Flynn wrote a couple of brilliant chapters on private cloud management and integration with App Controller, Service Manager and Orchestrator. It was a fine job we completed in early 2012, the book was published just before the beta of SP1 was announced. We simply didn’t have the opportunity to wait until SP1 was out and digest and explain all the new features that arrived with Windows Server 2012. Fortunately Damian has joined Nigel Cain (who is a Senior Program Manager for Windows Server and System Center) to write a blog series on Technet in eight installments between Jan 2013 until July 2013, just to explain the new Virtual networking technology in VMM 2012 SP1

Another year came and here was Aidan again, asking me to join him on his new venture: the Windows Server 2012 Hyper-V Installation and Configuration Guide. Although I really liked the subject and wanted to go into great depth to learn all this cool stuff, I was simply too busy doing all those great Hyper-V and System Center projects for Inovativ. Our family was also heavily burdened by the unfortunate adventures of one of my sons, which more or less influenced me most of 2012.image Writing a book was out of the question.

Convincing as Aidan can be, he said he had his author team complete, again with Damian Flynn and Patrick Lownds plus Michel Luescher, “a virtualization junkie working as a consultant at Microsoft” as he calls himself. The only omission was a technical editor fit for the job. And that’s why he asked me.

I am more than honored to be mentioned quite extensively in the Acknowledgements of the Windows Server 2012 Hyper-V book by each and every author. I really felt like being part of the author team but in the role of both learning, correcting but most of all improving. I remember advising Aidan to split one chapter into two because it was approaching 100 pages, more than twice as much as they had anticipated.

Having been the first reader (and I read the chapters multiple times), I can truly say this is a superb book that anyone interested in the technical secrets of Windows Server 2012 Hyper-V should buy. I can guarantee you will not one day regret having bought this book. There were moments I wanted to cry out how good these chapters were, thrilled by the sheer excellence of the product and the very talented explanatory writing in the 600 pages of this Must-have-Hyper-V-version-3 book.

The book can be pre-ordered now and will be published on March 25th. The European release will be April 5th. See the Windows Server 2012 Hyper-V Book Release FAQ.

I will not wait till my free copy arrives (Sybex, hope you are reading this) as I have already pre-ordered it myself, but wouldn’t mind a few extra copies to give away.

Last tickets for event up for grabs

imageAs you can see from the screenshot, only a few tickets are left for the event on April 16th, 2013. The event will be presented in Dutch which is unfortunate for several of our followers in the neighboring countries who wanted to attend. I hope to convince my fellow speakers to present in English again so the last 15 tickets could have been easily sold by now. The event is free by the way.

If you already know you cannot make it, please return your tickets!








Dell Compellent and Offloaded Data Transfer (ODX)

I just finished a remote support session for a customer in New York. My task was to check a Windows Server 2012 cluster using PowerEdge M620 blades with 4x10GbE connected to a Dell Compellent (6.3.1 firmware).

I just had a small window of opportunity to create a fixed sized VHDX (25GB and 250GB).

new-vhd -path C:ClusterStoragevolume125GB.vhdx -size 25GB –fixed

new-vhd -path C:ClusterStoragevolume2250GB.vhdx -size 250GB –fixed

Both completed in under 3 seconds. Wow!!! 

ODX in its purest form.

So let me reiterate my advice to new SAN array buyers. The first question you should ask your SAN vendor. Does it support ODX?  If the answer is negative or if they promise ODX in their next release, just tell them to take a hike and move on to a capable SAN vendor.



Wiki for Windows Server 2012 Cluster Hotfixes

[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.

Looking for Windows Server 2008 R2 Cluster and Hyper-V Hotfixes?

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.

Microsoft Virtual System Migration Service–Service is missing

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 ServicesServername" Servername
  • setspn -S "Microsoft Virtual System Migration ServicesServername.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.

5Nine Security Manager for Windows Server 2012 Hyper-V part-2

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.

Anti-virus/ Anti-mallware

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:

image Open the menu ‘Settings’ and select ‘Antivirus’.
image You can select which VM’s you want to scan with 5Nine virusscanner.
image The extension tab allows you to configure which file type extension must be scanned or exclude from scanningUnfortunately it is not possible to exclude filepaths and this is a feature that is needed in an enterprise antivirus solution.

5Nine let me know that in one of the following versions this feature still will be added!

image And this is an interesting feature which I will explain a little bit more…

SMB 3.0 and ODX both appear in EMC VNX mainstream release

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.
