Since I recently saw cloudstack have add this( https://cwiki.apache.org/confluence/display/CLOUDSTACK/GPU+and+vGPU+support+... ). And iGVT( https://01.org/zh/xen/blogs/wangbo85/2014/intel-gvt-gxengt-pubic-release?lan...) is released. If ovirt add this, it'll be very competitive for ovirt in VDI platforms.
See below the response I got about 1 year ago, I don't know the current plans/status...

Hi,
I'm afraid that none of these cards will work. IIRC it was explained for nVidia approach that it would be necessary to add their closed-source code to qemu which is not going to happen. You might have better luck with AMD card "passthrough" approach but I'm not sure if GPUs can be passed through qemu/kvm and if so, how the GPU-rendered image then gets displayed. So YMMV and don't expect much.
There is a WIP effort for qemu though that is hardware vendor agnostic - it's based on creation of virtual GPU in qemu called Virgil that passes 3D drawing commands to GPU on host. The project is in initial stage though so it won't be ready even for testing for quite some time. FWIW, there has been discussion about it on spice-devel in recent days and it will be presented on upcoming KVM forum so you can get pretty clear picture about its status from these sources.
HTH,
David
Hello, There is quite active effort to implement device passthrough (including GPU, nics, usb etc.)[1]. Physical GPU passthrough can be considered generic PCI passthrough which should be ready for oVirt 3.6. As for the vGPU, that will depend on technology used - SR-IOV would be supported along PCI passthrough, anything else might need additional work on our side.
