Hello @binhex   I found the solution and I post it here for the people in my case. Under our proxmox host:   nano /etc/pve/lxc/XXX.conf (XXX is the ID of the proxmox CT) Add at the end: lxc.autodev: 1 lxc.hook.autodev: sh -c "mknod -m 0666 ${LXC_ROOTFS_MOUNT}/dev/fuse c 10 229" lxc.cgroup.devices.allow: c 10:200 rwm lxc.apparmor.profile: unconfined And : nano /etc/modules   add iptables if missing   # /etc/modules: kernel modules to load at boot
