Virtualization with Intel's GVT-d on Mid-2015 Macbook Pro I have a mid-2015 15" Macbook Pro. The iGPU is part of Intel's Iris Pro brand, which as I understand allows a VM to access the GPU directly with a native driver through GVT-d.

I would like to run a Linux guest OS in this manner, giving it native access to the iGPU so that it can run a native driver (and thus have OpenGL 4.3 support). I have no idea how to go about doing this, though. I've heard there are forks of QEMU/KVM with GVT included, but I have no idea how to go about setting up a VM with one of those.
Some further research has produced somewhat contrary answers. This forum thread seems to suggest that it's possible, but not for a Mac OS host. Conversely, here it's suggested that it's not possible to implement on a type-2 hypervisor like Virtualbox.

I'm not entirely sure what to make of this, except maybe to suspect that it's possible to time-share an Intel GPU across multiple VMs with this method, but not to time-share an Intel GPU across a host and a guest.

Either way, it seems the answer to this question would have to be No for the time being.
