[Xen-devel] 1 GPU multiple VMs

[Jacobs Jordi <Jordi.Jacobs@xxxxxxxxx>]

Hi,

I am wondering how GPU sharing could/should be implemented for the Xen Hypervisor.

I have come across several papers that explain many possibilities on GPU sharing for multiple VMs but I'm not sure wich one would be the best solution for Xen.

API remoting (gallium3D) (ex. Xen3D project)
Mediated passthrough (Multiplexing the GPU while maintaining the different contexts.)

Can you guys give me your idea on the matter?
Please also mention any existing projects you know that are related to this problem.

Thanks in advance,

Jordi
