We are running a 2012 server that has the hyper v role installed. We have spun up a 2008 r2 virtual machine running SP1. We have an ati firepro v5800 video card in the server. We've gone through all the requirements to enable remoteFX in the vm, however, when we enable RemoteFX on the 2008 r2 VM, the display adapter goes from showing up as a hyperv video carfd to a standard vga card. I also spun up a windows 7 vm on this same hyper v server and the remotefx seems to work ok on that server. Atleast I get the message that remotefx is activated when I try to connect to the vm through the hyperv console. What could be preventing remotefx from working in the 2008 r2 VM?
