I will like to observe how this technology improves over time. There are some interesting possibilities here.

Seems interesting. PCI/VGA passthrough has been around for a long time but requires an IOMMU unit on the motherboard and CPU, BIOS, GPU support for VT-d or AMD-V for anything to work.

So this is virtualizing the GPU rather than passing it directly into the VM? One problem with VGA passthrough is that by passing it over, you prevent the host OS from accessing the GPU hardware. Thus its necessary to have two GPUs from my understanding.

Michael, can you tell us if this technology would work with Windows guests inside KVM and support hardware accelerated Direct3D? Or is this only a Linux guest technology?

[bmoez]

Currently only Linux guest support is provided.
This will answer all your questions http://events.linuxfoundation.org/si...Solution_1.pdf

@Xaero_Vincent:

the post on the mailing list states that only Linux guests are supported right now.

My question is, what Intel graphics hardware is this supported on?

- Basic functions of full GPU virtualization works, guest can see a full-featured vGPU.
We ran several 3D workloads such as lightsmark, nexuiz, urbanterror and warsow.


So yes, it's really a vgpu, and this can be shared across multivm. I think for the display output you need a remote protocol like spice or vnc.

I suppose AMD and Intel doesn't have GVT?

Could this functionality be extended to support GPU virtualization for AMD and Nvidia users too?

[whitecat]

How does it compare/compete with virgil ?

[dragonn]

Does this work without VT-d? Second it will be fine if I could use my integrated gpu for VMs and on the host system my main Nvidia card on standard PC not laptop.
