There are loads of documented changes and improvements to the RemoteFX technology stack in Windows 8 Server, so of course I’m keen to try it out.
I’ve now got my hands on three Dell Optiplex 990 systems, each with 12GB RAM and a Radeon HD5450 GPU. Not cutting-edge perhaps, but fine for testing basic functionality.
I was a little confused after I enabled the Hyper-V role, restarted the machine and went into Hyper-V Manager to see what the situation was with RemoteFX. I was presented with a UI which suggested that RemoteFX was already enabled, but that no supported GPU could be found: “None of the physical graphics processing units (GPUs) on this computer support RemoteFX”.
This was a little strange as I’ve used the same GPU for RemoteFX on Windows 2008 R2 SP1, and while it’s not a particularly beefy card, it certainly works.
Turns out that there’s a little bug in the UI, which Rafael Rivera picked up here. Simply enabling Hyper-V doesn’t enable RemoteFX. This still needs to be done by installing the Remote Desktop Session role on the server. In my case, I installed the role as well as the Remote Desktop Session Host and Remote Desktop Virtualization Host.
Once installed and rebooted, the RemoteFX UI in Hyper-V Manager was correctly populated with the physical GPU. RemoteFX here we come
