Thanks all for the feedback.
When we bought the servers, they put some Nvidia Quadro P4000's in, but I can't
seem to find anything that says they support vGPU.
I wasn't aware of the license server requirement for Nvidia, but the pricing
isn't too bad, so I can probably get that pushed through. Anyone aware of which AMD
cards are supported by oVirt? I have only found a list of Nvidia cards.
Thanks,

Hello,
updated list of supported GPUs for vGPU functionality should be this one:
https://docs.nvidia.com/grid/gpus-supported-by-vgpu.html
<
https://docs.nvidia.com/grid/gpus-supported-by-vgpu.html>
and P4000 seems not to be present
So you could use the other supported method, with passthrough Gpu, following what
described here for qemu command line:
https://docs.nvidia.com/grid/latest/grid-vgpu-user-guide/index.html#using...
<
https://docs.nvidia.com/grid/latest/grid-vgpu-user-guide/index.html#using...
and driving oVirt to do so with vdsm hook qemucmdline
why a hook? we have a “native” ovirt support for both GPU and vGPU since cca 4.1.
There was a hook initially, but that’s no longer needed…since 4.2 iirc
I think we also tested some Intel’s GTV-g card...

I donna if the doc here is up to date, not tested lately:
https://www.ovirt.org/develop/developer-guide/vdsm/hook/qemucmdline.html
<
https://www.ovirt.org/develop/developer-guide/vdsm/hook/qemucmdline.html>
I think the persist command in case of node is not necessary with NG any more
Developers could confirm and eventually point to the correct page for the hook guide?
