RemoteFX: Guest OS Driver Issue

$

Hi All,

I have used this forum a lot but this is my first post (I usually find the answer I need).... exciting times!

I have just created a Hyper-V server with Server 2008 R2 and set up a virtual desktop pool. All is working well. I have now moved on to trying to get RemoteFX working to improve the end-user experience. Here is my setup:

  • Server 2008 R2 Enterprise SP1: Hyper-V server
  • Windows 7 Enterprise SP1: virtual guest OS (Hyper-V integration services installed)
  • Nvidia NVS 300 physical GPU installed in host with latest driver (DirectX 11 support and WDDM 1.1 driver installed)
  • Physical host server is using 2 Intel Xeon E5506 quad core CPUs (SLAT enabled)


I feel confident that I have met all of the prerequisites for RemoteFX. I'm aware that I am not using one of Nvidia or AMD's offically listed GPUs for RemoteFX but the spec of my card still meets the requirements needed for RemoteFX.

RemoteFX is installed onto the host server and I have added the 'RemoteFX 3D Video Adapter' to the virtual machine. The virtual machine boots up fine and I can log in...... but this is where it gets interesting...........

At this point I am led to believe that the guest OS should start installing the driver for RemoteFX... but it doesn't. It does nothing. In 'Device Manager' I have TWO 'unknown devices' and my GPU is listed as 'Standard VGA Adapter'. If I remove the 'RemoteFX 3D Video Adapter' from the virtual machine and reboot, the two 'unknown devices' disappear and the GPU changes to 'Microsoft Virtual Machine Bus Video Device'...... so these unknown devices are clearly associated with RemoteFX.

So my question: why is the guest OS not installing the correct RemoteFX driver? I have been on this for hours so I am going to be so grateful to anybody who can help.

Thanks
Nick
