Description: Virtual machines configured with a 3D video adapter can only run on systems that have a SLAT capable CPU.
This issue occurs when you try to start a RemoteFX virtual machine on a Hyper-V server that does not have a Second-Level Address Translation (SLAT)-enabled processor.
The processor in the RemoteFX server must support SLAT. In virtualization scenarios, hardware-based SLAT support improves performance. On Intel processors, these are known as Extended Page Tables (EPT), and on AMD processors, they are called Nested Page Tables (NPT).
For information about how to identify other hardware requirements for RemoteFX, refer to the following Microsoft TechNet article:
