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.
