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
not sure, but I would say 7.4 could be too old for all this.
I’d recommend to try all that on host 7.6 and guest 7.6
'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:

graphic card (rev 04)

Could the qxl module be somehow blocking the nvidia driver? I tried
blacklisting the driver in grub, though that didn't work anyway.
Thanks in advance for any help.
