Q: Why doesn't my Windows 8 Pro virtual machine see the RemoteFX graphics adaptor on my Windows Server 2012 Hyper-V server?

A: RemoteFX has many capabilities, one of which allows a physical GPU to be virtualized and allocated to virtual machines (VMs) in the form of virtual GPUs, which can then be used by the guest OS.

I assume you performed all the configuration such as ensuring the following:

  • A Windows Server 2012 graphics driver is installed
  • The graphics card supports DirectX11
  • RD Virtualization Host is enabled on the Hyper-V server
  • Hyper-V settings for RemoteFX are complete
  • The Windows 8 VM has a RemoteFX graphics adapter added

But still you found that after connecting from a Windows 8 machine using Remote Desktop Protocol (RDP) and looking at the properties of the graphics in the VM, only a normal graphics adapter is shown and the DirectX capabilities aren't available (see screen shot below).


The reason is that RemoteFX is a feature of the Enterprise edition of Windows 8. It worked in the Consumer Preview (beta) of Windows 8, but for the Release Preview, the RemoteFX drivers aren't part of the Professional edition, and RemoteFX is therefore not available.

This will be the case for the final release of Windows 8. The Enterprise edition of Windows 8 must be used in the VMs that will use RemoteFX.

What you want to see in Device Manager and DXDIAG is shown in the screen shot below. The key point is that the display adapter should be Microsoft RemoteFX Graphics Device - WDDM.
