IIRC oVirt 4.3 should have the basic hooks in place for mdev
passthrough. For nvidia this mean you need the vgpu drivers and a
license server. These licenses have a recurring cost.

AMD's solution uses SR-IOV, and requires a custom kernel module that is
not well tested YMMV.

You can also passthrough entire cards in ovirt without any drivers,
granted since the amount of GPU's you can stuff into a server is limited
this is probably not ideal. Nvidia blocks this on consumer level cards.

Intel also has a mdev solution that is built into mesa / the kernel
already, we have used it with VCA cards in the past, but perhaps the new
Intel GPU's support it as well? Intel is the only option that will allow
you to feed the framebuffer data back into spice so you can use the
ovirt console. All other options require you to create a remote session
to the guest directly.
