There is nothing output, when I execute "podman info". The following info, I add "--log-level debug". $ podman --log-level debug info INFO[0000] podman filtering at log level debug DEBU[0000] Called info.PersistentPreRunE(podman --log-level debug info) DEBU[0000] Found default OCI runtime /export/home/rsync/.local/container/sbin/runc path via PATH environment variable DEBU[0000] Using conmon from $PATH: "/export/home/rsync/.local/container/bin/conmon" DEBU[0000] Initializing boltdb state at /tmp/1212/14810/share/containers/storage/libpod/bolt_state.db DEBU[0000] Using graph driver overlay DEBU[0000] Using graph root /tmp/1212/14810/share/containers/storage DEBU[0000] Using run root /tmp/containers-user-1212/containers DEBU[0000] Using static dir /tmp/1212/14810/share/containers/storage/libpod DEBU[0000] Using tmp dir /tmp/podman-run-1212/libpod/tmp DEBU[0000] Using volume path /tmp/1212/14810/share/containers/storage/volumes DEBU[0000] Set libpod namespace to "" DEBU[0000] Not configuring container store DEBU[0000] Initializing event backend file DEBU[0000] Configured OCI runtime crun initialization failed: no valid executable found for OCI runtime crun: invalid argument DEBU[0000] using runtime "runc" from $PATH: "/export/home/rsync/.local/container/sbin/runc" DEBU[0000] Configured OCI runtime kata initialization failed: no valid executable found for OCI runtime kata: invalid argument DEBU[0000] Configured OCI runtime runsc initialization failed: no valid executable found for OCI runtime runsc: invalid argument DEBU[0000] Configured OCI runtime krun initialization failed: no valid executable found for OCI runtime krun: invalid argument DEBU[0000] Using OCI runtime "/export/home/rsync/.local/container/sbin/runc" INFO[0000] Setting parallel job count to 4
Thanks for reaching out. Is this also on CentOS 7? If so, the only supported Podman version is 1.6.4 on CentOS. Podman v4.x will not work in most cases as the host system is just too old. On Mon, Aug 8, 2022 at 12:02 PM None via Podman <podman@lists.podman.io> wrote:

Yes, it's CentOS 7. Is podman v4.x support CentOS Stream 8? Or which is the best OS?

Yes, Podman v4.x is in CentOS Stream 8 and 9.

That really depends on your use case. In this specific case, CentOS 7 is just too old for modern container tools as, for instance, some kernel features are missing.

What are kernel features missing? How could I get the kernel features list?

I think most features relate to file systems and rootless support. Since CentOS and RHEL 7 only support v1.6.4, the list of kernel features will likely have increased. But we don't track them anymore since such old systems are not supported.
