We discovered that the ubuntu 18.04 machine had a configuration change to get rootless working with nvidia: "no-cgroups = true" was set in /etc/nvidia-container-runtime/config.toml Unfortunately this config change did not work on Centos 7, but it did change the rootless error to: nvidia-container-cli: initialization error: cuda error: unknown error\\\\n\\\"\"" This config change breaks podman running from root, with the error: Failed to initialize NVML: Unknown Error Interestingly, root on ubuntu gets the same error even though rootless works. _______________________________________________ Podman mailing list -- podman(a)lists.podman.io To unsubscribe send an email to podman-leave(a)lists.podman.io
