.Leapp does not support NVIDIA drivers for operating system upgrades If you attempt to perform a Leapp OS upgrade with NVIDIA drivers, the system upgrade fails with the following error in `/var/log/leapp/leapp-report.txt`: ---- Summary: Leapp has detected that the NVIDIA proprietary driver has been loaded, which also means the nouveau driver is blacklisted. If you upgrade now, you will end up without a graphical session, as the newer kernel won't be able to load the NVIDIA driver module and nouveau will still be blacklisted. Please uninstall the NVIDIA graphics driver before upgrading to make sure you have a graphical session after upgrading. ---- *Workaround:* . Remove the NVIDIA driver. For example: + ---- $ sudo dnf remove -y NVIDIA-vGPU-rhel-8.4-525.105.14.x86_64 ---- . Remove the loaded module kernels: + ---- $ rmmod nvidia_vgpu_vfio $ rmmod nvidia ---- . Upgrade the Compute node: + ---- $ openstack overcloud upgrade run --tag system_upgrade --limit <compute-0> ---- . After the server reboot, re-install the NVIDIA drivers for the appropriate operating system (RHEL 9.2). . If necessary, re-create the `mdev` devices.
