RemoteFX vGPU in Windows 8 Hyper-V? (win8 on win8) RRS feed

  • Question

  • Is it possible to use the RemoteFX vGPU functionality between a Windows 8.1 x64 Hyper-V host and its Windows 7/8 guest vm? (or is this only possible with Windows server versions?)

    Thanks

  • I re-read your original question:

    vGPU is only consumable by client os in a VM, and only Server installed on the bare metal can present it to a VM.

    If you have Server in a VM you cannot assign vGPU to the Server VM.  But Server installed on the bare metal running RDS can use the GPU for sessions.

  • There is a new synthetic GPU.

    but the feature you are asking about is server only.

    but, client requires SLAT t force the better graphics experience for the local vm console.

  • Thanks Brian,

    There is a new synthetic GPU.

    Are you referring to RemoteFX vGPU (virtual GPU), or something else?

    but the feature you are asking about is server only.

    Right, so it will only be available when Windows Server is the operating system installed on the "metal"?
    (there have been various mentions on the net that this would be available in the Hyper-V bundled with Win8Pro as well, but that seems to be wrong then)

    but, client requires SLAT to force the better graphics experience for the local vm console.

    You mean the physical host CPU should support SLAT, or are you referring to some Hyper-V setting?

    Best regards

  • The physical CPU must support SLAT for client Hyper-V - it is tested for at startup time and enforced.  Specifically to make sure that folks have a good graphics experience with the VM consoles, and MSFT avoids all the negative graphics comments from the 2008 days when folks were running Server in this way.

    To get the vGPU you need: 1) Hyper-V Server or Server with the Hyper-V Role installed on the bare metal 2) you need a graphics / GPU card on the supported list (this is actually important).

    The virtual gpu - yes.

  • Thanks Brian, that clears things up wrt the required host OS for vGPU support. It does make me want to ask followup questions about Hyper-V Server, but I'll do that in another thread :-)

    Best regards

  • Is anyone aware if the requirements for RemoteFX require the full suit of Remote Desktop Services, i.e. connect broker, virtualization host, license manager, etc, or can it be done with just Server 2012 on the bare metal and a Windows 8 guest host?
