WEBINAR: Troubleshooting Microsoft Hyper-V


If you’ve been in IT for any length of time, you’ve likely gotten that phone call that you never want to get: Everything is broken! It’s the end of the world! The sky is falling! Your Hyper-V Host or Cluster is broken and you are the person to fix it!

Where do you start?

What are the most common things to look for?

These are exactly some of the questions we’ll be covering in our next webinar, on February 25th, 2016 at 4pm CET / 10am EST!

Microsoft Cloud and Datacenter Management MVPs Didier Van Hoye and Andy Syrewicze will be answering these questions, and will also be sharing some tales from the trenches.

In this webinar you’ll learn Hyper-V troubleshooting basics and solutions to common problems. You’ll also see some Hyper-V oddities that were encountered by Didier and Andy and how these issues were ultimately resolved and with what tools.

It’s one thing to setup and run a virtualization solution. It’s another thing to fix it when it’s broken.

Sign up now to join us on February 25th, 2016 at 4pm CET / 10am EST (30-45mins + live Q&A!) for some tales from the trenches!


How to: Initialize, format and label disks during OSD Task Sequence in SCCM 2012 R2

During a task seuence in Microsoft SCCM 2012 R2, the operating system and applications are installed on the C: drive in most situations. But in some deployments, you definitely want to create more disks. For example, you want to create a D: and E: partition for storing some other data. Maybe for Microsoft SQL or Exchange installation, databases, logfiles or just some other data.

The following script will do all these steps for you during the task sequence. The script initialize, format, partition and label the disks for you….fully automated! :)

The script first checks how many disks are attached to the server.
If there is only one disk attached, you’ll have only a C: drive available after the deployment.
If there are 2 disks attached, you’ll have a C: and D: drive avalailable after the deployment.
If there are 3 disks attached, you’ll have a C:, D: and E: drive available after the deployment.

The CD-ROM drive will alse changed from E: to X:.

WEBINAR: Scripting & Automation in Hyper-V without SCVMM


Save the date!!

the 10th of december there is a free webinar about automating tasks in your Hyper-V environment without the user of Microsoft System Center Virtual Machine Manager (SCVMM).

This is realy usefull for that customers who don’t have System Center within their environment! Automation and scripting some tasks can save you a lot of time and money!
MVP Thomas Maurer and Technical Evangelist Andrew Syrewicze will present this webinar!


First look at Windows Server 2016 Technical Preview 2 Build 10074

Microsoft has released a new version of Microsoft Server 2016 Technical Preview 2, so I’ve installed this version immediately within my Hyper-V environment. After starting the setup, you’ll see there’re two versions:

  • Windows Server Technical Preview 2
  • Windows Server Technical Preview 2 (with local admin tools)

The difference between theese two versions is the User Experience. In previous version of Windows, it was called Windows Server Core Edition. So the version without the local admin tools, the user has no option to enable/install the graphical user interface (GUI).

After the installation, you’ll see that there’s a difference between the User Experience. One version, the Server Manager is available and the other version has only a command prompt available. You’ve to manage this server from another server with the Remote Server Administrative Tools (RSAT). The version with the admin tools included, there’s a possibility to enable the Graphical User Interface (GUI).

After a reboot, the server is turned on with a Graphical User Interface (GUI) and it looks pretty cool!! And YESSSS, the start menu is back again :) What a great time for some users!! With this new version of Windows Server, there’s is a complete new “world of bits and bytes”….

Free Ebook: Microsoft System Center Deploying Hyper-V with Software-Defined Storage & Networking

How to: Deploy packages using collection variable with ConfigMgr 2012 R2

During a OS deployment you don’t want to deploy all your packages and software to every workstation. You can deploy the software after a full OS deployment, but you can also deploy packages during the OSD using collection variables. Now it is possible to deploy packages only if a specific machine is a member of a collection. This collection can be query based, for example OU membership or Active Directory security group, or it can be static (direct membership).

In this example I’ve created a realy simple deployment, Adobe Reader 11.0. I’ve two virtual machines, SCWIN81-01 and SCWIN81-02. Both machines are members of the collection “Deploy – Windows 8.1 Enterprise x64″, where the task sequence is deployed on. Machine SCWIN81-01 is also member of the collection “Install – Adobe Reader 11.0″. This collection has a limited collection of “Deploy – Windows 8.1 Enterprise x64″. Both machines are deployed on the same time, the only difference is that machine SCWIN81-01 has Adobe Reader 11.0 installed and machine SCWIN81-02 not. Why……based on the collection variable during the OSD :)

1.) First create the collections
2.) Make the specific machines members of the right collections (query based or direct membership)
3.) Open the properties of the collection “Install – Adobe Reader 11.0″ and navigate to the “Collection Variables” tab
4.) Add one or more variables with some values. In this example the variable is “APP-AdobeReader” with the value “Yes”
5.) Open the task sequence and add a package installation step
6.) Add the package with the program and navigate to the “Options” tab
7.) Select “Add Condition” and select “Task Sequence Variable”
8.) Enter the collection variable you’ve created earlier with the same value. In my example:
Task Sequences Variable APP-AdobeReader equals “Yes”
9.) Select “Apply” and close the task sequence.
10.) Start the OSD on both machines and wait until the installation is done!
11.) Watch the differences between both machines, if everything is okay, one machine has Adobe Reader installed and the other not.

This is an extremely powerfull thing within ConfigMgr, and really helpfull is some scenario’s. For example VDI golden image deployments or hybrid environments with laptops/desktops or multiple organizations using one ConfigMgr environment. One main reason could be consolidation in task sequences. If you want, there should be only one task sequence for all you different deployments. This is why I’m loving collection varaibles! :)

Enabling Data Deduplication in Windows 8.1

When you do a lot of deployments whitin your Windows 8.1 Client Hyper-V machine, the disk space is getting more and more. Because I’ve only one SSD drive of 250 GB, the free space becomes critical. I’ve got to find a way to reduce it. I read a few blogs and found a solution which is the dedup. But data deduplication is not available whitin Windows 8.1.

This method is not officially supported by Microsoft ,however found a way to save my disk space.

This method requires the CAB files from the Windows Server 2012 R2.  Either you can get those files from a Windows Server 2012 R2 or you can download the files from my OneDrive here.
The files are as follow :

I downloaded the files to a folder as below and installed all the CAB files:

DataDedup_02    DataDedup_01

Next step is to install the CAD files on your Windows 8.1 machine. I’ve used DISM to install these files.

DataDedup_03    DataDedup_04

After you’ve succesfully installed the CAB files, you’re able to install the “Data Deduplication” role. I’ve also used DISM (see screenshot below).

DataDedup_05    DataDedup_06    DataDedup_07

The next step is to enable Data Deduplication on the volume or volumes. First I’ve readthe current free space on my E: drive. After enabling Data Deduplication on this volume, I’ve manually started the Data Dedup task.

DataDedup_08    DataDedup_09    DataDedup_10

DataDedup_11    DataDedup_12    DataDedup_13


But after enabling Data Depuplication and running the Dedup Job, there’s nothing happening!! Why?? Because the minimumFileAgeDays is 3 and my files on the hard drives are 2 days old :) So I’ve added the MinimumFileAgeDays to 0 (zero days). After running the Dedup Job again, let’s have a look on the current free space!! Dedup is doing his job!!! :) Cool!

DataDedup_15    DataDedup_16    DataDedup_17

DataDedup_18    DataDedup_19    DataDedup_20

DataDedup_21    DataDedup_22

The final screenshot are the commands I’ve used to configure this in my lab environment. Once again, this method is not officially supported by Microsoft.It’s a great way to save some disk space on your expensive SSD hard drive! Now you can deploy more virtual machines on the same hard drive, so happy automation and deployment!! :)
