[ovirt-users] vGPU not available in "type mdev"

Hello I followed the tutorial regarding vGPU but it's not working, i i guess it's a Nvidia licence issue, but i need to be sure. My node is installed using the node ISO image. I just removed the nouveau driver ans installed the nVidia one. My product is : "GK106GL [Quadro K4000]" My driver is : NVIDIA-Linux-x86_64-390.87 In the host peripherals I see my card (pci_0000_05_00_0) listed, but the column "type mdev" is empty, as the doc says I should see vGPU i guess something is missing. I took a look, there seems to be nVidia vGPU copatible driver, but no trace of it. The only vGPU stuff i found it's "NVIDIA VIRTUAL GPU" and i understand I have to pay to use vGPU on my nVidia card. is this correct or no ? If i'm supposed to pay is there a free workaround ? thanks for your help marc
