MICROSOFT ROK LICENSE ON HYPER-V GUEST

You all have dealt with this situation. You bought a new box for a customer. Then you adjust your plans, just because Hyper-V is cool. You think… Lets install Hyper-V on that box and create some VM’s on it. One with the SBS or Essentials Server and a few additional VM’s

Then you start to to setup the hardware, make sure you enabled Virtualization on that ML10 and off you go.

Installation of Hyper-V is a breath. Done in a few minutes. You place the Essentials media in the server and…

BANG

What the heck? The Essentials Server, deliverd with your HP Proliant ML10, is not gonne work..

Why?

The reason is quite simple. The installation Media of those ROK licences are checking some registry keys. 

So this is something we can resolve.

If you are/were installing this on Hyper-V 2008R2

  • Open the registry key HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Virtualization
  • Add a registry key of the type REG_SZ and name it BiosLockString
  • Enter the value : “Hewlett-Packard                 ” (Warning: After Hewlett-Packard there must be 17 white spaces!)

If you are/were installing this on Hyper-V 2012:

  • Open the registry key HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Virtualization
  • Add a registry key of the type REG_SZ and name it BiosLockString
  • Enter the value : “Hewlett-Packard                              ” (Warning: After Hewlett-Packard there must be 30 white spaces!)

If you want to install ROK licences on Hyper-V 2016/2019

I cannot help you with this at this moment. I have not done this yet. I presume the last option would work.

Cheers! and Happy HyperV-ing.
