[Req]: paravirtualized Vulkan support for Linux guests #668

3D Support

What problem are you facing?

Do you have any plans to implement paravirtualized GPU / Vulkan support for Linux guests? If that would be implemented, full featured OpenGL support can be achieved with zink.

qemu / kvm implement Vulkan with paravirtualization (Venus virtio-gpu driver), where guest Vulkan calls are passed through to the host Vulkan implementation. Doing something like this in virtualbox would really improve rather limited GPU acceleration in Linux guests that virtualbox currently implements.

How can we fix this?

Implement GPU paravirtualization with focus on passing Vulkan from guest to the host.

What alternatives or workarounds exist?

No good feature comparable alternatives

Anything else we should know?
