Hello,
I am currently running a VDI environment with server 2012 servers including a RDCB, RDVH, RDSH, RDWA and windows 8 clients. I am using remoteFX on the windows 8 clients with the help of 3 nvidia Quadro 6000 cards. RemoteFX works perfectly in windows 8; however, I built a windows 8.1 VM and remote FX will not work in this VM. When I log on to the vm and look under device manager the remoteFX device is listed but it gives an error of 43. All of the vm's have one monitor set in the remoteFX settings. In the event viewer of the windows 8.1 VM I am getting an error under RemoteDesktop Services vGPU-kModeDriver "The virtual GPU synthetic devie failed" and the other accompanying error is "The RDVGM kernal mode driver failed to start" I have removed all of the windows 8 VM's to confirm that all of the available memory of the GPU was not used and this didn't get any different results. The only difference I see is that one guest os is windows 8 and the other is 8.1. Does remoteFX not work in windows 8.1 by chance? Both OS's are Enterprise as well.
Thanks for any help,
Scott
