Hi, If you're using XenAPI then the good news is that GPU passthrough is implemented [1] and it works with NVIDIA. I've copied Guillaume that developed and tested the feature, he may be able to provide more details. I know at least that Guillaume had difficulties to do GPU passthrough with NVIDIA cards and libvirt/KVM.
