Proof of concept for GPU forwarding for Linux guest on Linux host.
Hi,
This is a proof of concept of GPU forwarding for Linux guest on Linux host.
I'd like to get comments and suggestions from community before I put more
time on it. To summarize what it is:
1. It's a solution to bring GPU acceleration for Linux vm guest on Linux host.
It could works with different GPU although the current proof of concept only
works with Intel GPU.
2. The basic idea
