GPU passthrough diagnostic commands
Use these commands to collect diagnostic information when troubleshooting GPU passthrough issues.
-
dmesg | grep -i 'nvrm\|nvidia' - Filters kernel log messages from the NVIDIA driver. Look for error codes prefixed with
NVRMor stack traces that indicate driver initialization failures. -
nvidia-bug-report.sh - Generates a compressed diagnostic report (
nvidia-bug-report.log.gz) that captures GPU state, driver versions, kernel logs, and system configuration. Attach this report when filing NVIDIA or Red Hat support tickets.
