How to solve multiple monitors problem after installing Hyper-V role

After I installed the Hyper-V role on my Windows 10 Pro laptop I noticed several monitors that didn’t exist :

Meerdere monitoren

I tried to re-create the problem by uninstalling the Hyper-V role, and after that the problem was gone. But ofcourse that isn’t a reasonable solution. After some investiging I found out that this is a common problem with the Intel HD 4600 graphics adapter. The solution is to revert to an older version of the driver.

You can find the driver here

After downloading the driver go to the properties of your display adapter and choose roll back driver.


After that choose Update driver and then choose the driver file you’ve just downloaded.


After rebooting you should notice that you’re extra monitors are gone :

How to convert OVA to VHDX for Hyper-V 3

If you have found yourself in a scenario where you would like to use Hyper-V as a test environment for your virtual machines, but you are using VMware ESXi Server,Citrix XenServer or VirtualBox then this tutorial is for you.

Required software

  • Microsoft Virtual Machine Converter 3.0 available here.
  • WinRar (or any tool you prefer to extract .tar files)
  • Your OVA export unzipped into a folder.


  • Download and install Microsoft Virtual Machine Converter 3.0.

An OVA file is simply a tar archive file containing the OVF directory. First you rename the .ova file to a .tar extension. Now you can use WinRAR and extract the .vmdk files within to get the virtual machines disks. VMDK is an open format used by VMware and other vendors.

Convert The Image

Next we will need to convert our VMware Image in order for Hyper-V to run it. This can be done using Powershell:

Copy you .VHDX to the folder containing you Hyper-V virtual machine.  When creating your new virtual machine, you must ensure you select “Generation 1” when choosing the generation of the virtual machine :

Updating Altaro Hyper-V back-up to latest version

I’m running Altaro Hyper-V back-up for some time now. Approx 1 year ago I installed it on my Hyper-V server and it has been running all the time with no problems. It never missed a back-up and so I didn’t saw the need to update to other versions. Most of the time upgrading back-up software can be quite tricky and I didn’t want to reboot my Hyper-V servers. Never the less I thought it was time to upgrade to the latest version. Here are the steps :


Click Check for updates,


Click Update now


And install the downloaded new version,






After hitting next I was pleased to see that all of my settings were still there and I didn’t had to reboot my server :


Here the “evidence” that it didn’t miss one back-up (No I didn’t deleted any errors Glimlach) :


I’m very pleased with the performance and stability of the product. So check it out. Click the banner on my blog.

Building a HYPER-V cluster for under $ 2000

Last week I was reading a ebook from my sponsor Altaro and I wanted to share this with my readers. This ebook is all about building a test environment capable of running a Hyper-V cluster.



The setup has looks quite a bit like my test environment. My Hyper-V cluster is build by 2 HP N40L microservers with each 16 Gb of memory (not the 8 Gb mentioned in the document). Officially it’s not supported but it works great. I also bought the ILO interface cards and therefore didn’t need to the buy the DVD drives.

For storage I’m using a NetApp FAS 2040 and a Qnap NAS. I’m always interested what other people use for their home environment and whitebox. So I thought it would be nice to share this link with you.


Would like to hear what you guys are running!

Hyper-V : Show the host server in a running VM

Today someone asked me how he could see what was the host Hyper-V server while running a virtual machine.

This is how you can do that :

When Hyper-V Integration Services is installed, the following registry key contains all the information you need :



You could easily find the server where this VM is running on from this point forward.




How to : Extend diskspace Windows 2008 (R2)

Many times people asked me how to extend a disk or I see them running Gpart or CLI tools while it’s not necessary. For those people I decided to write this blogpost.

Step 1 : Extend your disk in VMware settings

Go to you vCenter server and extend the disk. Simply go to the server you wish to edit, choose edit settings and click on the hard drive you wish to extend. Make sure you select the right drive! Glimlach


Now just fill in the amount of disk space you want for this drive. In mine example (I took this picture after resizing the disk) it was 30 GB and I added 20 Gb so the total is 50 Gb of storage.

Step 2 : Check your drive and extend it Glimlach

Before I extended the drive it was 30 Gb, check this picture :


Now we are going to extend this drive. Go to server manager/storage.


Click rescan disks, because Windows doesn’t see the extra available space right yet. After the rescan you must see extra unallocated space. Now select the volume (partition) you wish the extend. See below :

extend disk

Just go through these simple steps :






Et voila, the disk is extended :
