    Hello,
    I installed Microsoft Windows Server 2012 on the physical computer. This OS is a Hyper-V host. For testing purposes I installed Windows 8 Enterprise as VM guest and I installed RemoteFX on it and everything worked great.

    I also installed Windows Server 2012 as VM guest and in VM Hyper-V settings I added “RemoteFX 3D Video Adapter”. Same method was used in the Windows 8 Enterprise and RemoteFX worked without problem. But the RemoteFX is not working with this VM with Server 2012. There are two “Unknown device” items in the Device Manager.

    I read that RemoteFX is supported by Windows 8 Enterprise and Windows Server 2012 but now it looks like that Windows Server 2012 can be used only as host of VMs and not as VM guest.

    Please can somebody tell me is it possible to install RemoteFX on the guest VM with Server 2012?

    Thank you very much.

    I searched a little and found no direct answer to what you are asking.

    The closest reference is at http://blogs.technet.com/b/windowsserver/archive/2012/05/09/windows-server-2012-remote-desktop-services-rds.aspx , which states that:

    "In Windows Server 2012, the vGPU feature is expanded and all Windows 8 virtual machines can take advantage of a DirectX 11 capable GPU, either emulated in software (softGPU) when no GPU is present in the host or para-virtualized and hardware-accelerated (vGPU) when a DirectX11 compatible video card is present in the host. "

    No reference to edition is made and it is now known that only the Enterprise Edition of the Windows 8 client OS runs the RemoteFX vGPU (see http://www.microsoft.com/en-us/windows/enterprise/products-and-technologies/windows-8/enterprise-edition.aspx and I refer to my and others' experience with the W8 Release Preview).

    Cheers,

    Here's another link that suggests that what you are trying is not possible (or at least, standard practice :) ) - http://www.thegreenbutton.tv/forums/viewtopic.php?f=49&t=3189

    This technology is new to the extent that without more intervention by knowledgeable Microsoft personnel on these fora, little more than indications can be obtained.

    Hi,

    vGPU is not supported for a Server 2012 VM.  I recommend you remove the RemoteFX adapter from the VM settings.  If you have RDSH installed on Server 2012 you may use all of the RemoteFX features except for vGPU.  You may not need vGPU in your Windows 8 Enterprise VM.  Please test with and without it before deciding.

    RemoteFX Features for Windows 8 and Windows Server 2012

    Thanks.

    The table in http://blogs.msdn.com/b/rds/archive/2012/11/26/remotefx-features-for-windows-8-and-windows-server-2012.aspx  following the subtitle "RemoteFX features on remote computers"may lead one to think  that Windows 7 EE SP1 with RDP 8.0 is a substitute for Windows 8 EE for 3D graphics support over WAN. This facility requires at least:

    (a) RemoteFX vGPU

    (b) RemoteFX Adaptive Graphics

    (c) Remote FX over WAN

    While (a) has been a feature of RDP since version 7.1, (b) and (c) have been introduced in RDP 8.0, leading one to think that W7EE SP1 may now be used as the platform for rich multimedia delivery from a VDI.

    There is, however, a critical caveat in the use of RDP 8.0 on Windows 7 EE SP1 (http://support.microsoft.com/kb/2592687?ppud=4&wa=wsignin1.0) :

    "Virtual desktops that have RemoteFX vGPU installed cannot use RDP 8.0"

    This retains Windows 8 EE's sole occupancy of the position of OS for a VDI that is to deliver rich multimedia to the remote desktop client.

    Cheers,

    Etienne

    Hi,
    thanks for your advices.

    Please can you tell me what is it mean when the RemoteFX vGPU will not be installed? I suppose that the 3D graphic will not be accelerated (it will not be possible to use DirectX) but for example the media streaming redirection will work because it do not need the vGPU. Am I correct?

    Thank you.

    Yes, that is the way that I understand this, though I have not tried this out directly to answer with certainty.

    RemoteFX is a set of features that are related in the sense that they all contribute in enhancement of the multimedia experience for a Remote Desktop client that connects to a RemoteFX server. The RemoteFX server is the machine, whether virtual  or physical that is providing one or more of the RemoteFX features.

    Windows 8 Enterprise Edition has the largest set of features, including the facility to present a DirectX-compliant virtual graphics adapter to applications running on it. On the other hand, a Windows Server 2012 RDSH will not present a DirectX-compliant virtual graphics adapter to applications running within the session but will redirect ***WMV*** media to the client for playback at the client. This applies to the case of a client that is equipped with the facility to play WMV media, which is not a default facility i.e. not available on all remote desktop protocol clients.

    Cheers,

    Etienne
