Phoronix: Vulkan VirGL Ends The Summer Being Able To Execute A Compute Shader

One of the most interesting projects we've seen attempted for Google Summer of Code 2018 was adding Vulkan support to VirGL for allowing Vulkan access within guest virtual machines...

Vulkan access to hardware accelerated graphics hardware on the host?

Good to know that GSoC is finished. I've been stalking Nathan's github repos and gists way too long. Good job on the work!

Sounds dangerous. The Vulcan API command stream over virgl from the guest to the host cannot be verified by the host. The host will blindly execute the commands. The guest could segfault the host or worse. A bad/evil guest could probably read out memory space to other virtual machines. I assume the Linux host kernel is probably going to need some Vulcan extensions to make this safe/r.

That being said Vulcan is a lot less convoluted then how virgl works now.
