[ovirt-users] Re: vGPU VM not starting

Dear All, Similar issues with a clean install https://www.dropbox.com/s/jf9pwapohn5dq5p/vdsm.gpu2.log?dl=0 Above is the dropbox of the log of the clean install. This VM has a custom "mdev_type" of "nvidia-53" which relates to a specific GRID P40-24Q instance. Even looking in /sys/class/mdev_bus/*/ you see that there has been correctly a vGPU slice created as part of the boot of the machine, but still you get this error: 2018-05-17 14:19:42,757+0100 INFO (vm/1bc9dae8) [root] /usr/libexec/vdsm/hooks/before_vm_start/50_vfio_mdev: rc=1 err=vgpu: No device with type nvidia-53 is available.
