[ovirt-users] Re: vGPU on ovirt 4.3

I've been able to trick consumer GPUs into working with KVM on machines that I also use for oVirt, but oVirt itself is constructing the XML files for KVM on-the-fly, so you'd have to fiddle with the code that builds them: I haven't even found that yet.

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.
