Hello, does anyone is having issues with device passthrough on oVirt 4.5?
I can passthrough the devices without issue to a given VM, but inside the VM it
fails to recognize all the devices.
In my case I’ve added 4x GPUs to a VM, but only one show up, and there’s the
following errors inside the VM:

On the host this shows up on dmesg, but seems right:
