[Moayad]

Thank you for the output!

Could you please try to get rid of the hook from the LXC config espeically the `modprobe tun`. You can copy the LXC config as a backup `cp /etc/pve/lxc/111.conf /root/111.conf-backup`

And try to start the LXC, and run the `modprobe tun` manually?


Can you also please post the output of `ls /lib/modules/6.8.12-4-pve` command?

I try remove autodev script under 6.8.12-3,lxc start success.

6.8.12-4-pve modules:

root@pve8:~# ls /lib/modules/6.8.12-4-pve/
build              modules.builtin            modules.dep      modules.softdep      zfs
kernel             modules.builtin.alias.bin  modules.dep.bin  modules.symbols
modules.alias      modules.builtin.bin        modules.devname  modules.symbols.bin
modules.alias.bin  modules.builtin.modinfo    modules.order    weak-updates

If remove lxc.hook.autodev: sh -c "modprobe tun" line and start lxc succssful,and after run "modprobe tun",containers looks ok.
