We need a new hardware architecture to elegantly enable containment and sandboxing. Every application should have its own isolated virtual environment and OS for execution. Like Qubes, but with every environment capable of utilizing the full hardware simultaneously (that is, managed by the hypervisor).
Direct access to the video hardware is the main thing that holds back the virtualization of gaming or other graphics-heavy activities. We desperately need a solution to that.
This is kind of already available for VDI if your willing to accept the overhead of multiple OS instance. Nvidia GRID and similar GPU / Compute boards can handle multiple simultaneous users.
The problem is COST. These are designed for VDI servers supporting 25/50/100 desktop users not 1 gamer and are priced as enterprise equipment.
