Hi,
I’m having trouble getting my Nvidia vGPU to work on a VM.
Setup: RHEV 4.2 on RHEL 7.5, Tesla M60 (switched to graphics mode). I’m using the NVIDIA-GRID-RHEL-7.5-410.92-410.91-412.16.zip package from Nvidia.
On the hypervisor, I’ve installed the NVIDIA-vGPU-rhel-7.5-410.91.x86_64 rpm. vfio kernel modules are loaded, nvidia-smi shows the card, and I can see all the vGPUs via vdsm-client
I’ve created a CentOS 7.4 VM and added a ‘B’ type vGPU instance in ‘custom properties’. I’ve configured gridd.conf to point to the license server and it reports picking up a license in /var/log/messages. I installed the driver via the .run file (NVIDIA-Linux-x86_64-410.92-grid.run). The nvidia kernel module is loaded, but so also is the ‘qxl’ paravirtual driver.
lspci reports:
00:02.0 VGA compatible controller: Red Hat, Inc. QXL paravirtual graphic card (rev 04)
00:07.0 VGA compatible controller: NVIDIA Corporation GM204GL [Tesla M60] (rev a1)

I’ve tried blacklisting the qxl module on the VM in case it is blocking the nvidia driver (though that didn’t work anyway). I suspect it is something on the hypervisor.
I’ve tried running nvidia-xconfig to generate a xorg.conf as well as a custom one specifying the BusID of the card, but neither works (same error).
Thanks in advance for any help.
