Hello, Looking at the lxc logs exclusively I couldn't figure out what's going on, or if it's related to AppArmor. Could you also provide the kernel logs from the host and from the container?

This is my config: # Template used to create this container: /usr/share/lxc/templates/lxc-debian # Parameters passed to the template: -r jessie # Template script checksum (SHA-1): 70e3d3a3adf290e12fc3522b2066039e079d8f1d # Common configuration lxc.include = /usr/share/lxc/config/ubuntu.common.conf lxc.net.0.type = veth lxc.net.0.hwaddr = 00:16:3e:9c:68:09 lxc.net.0.flags = up lxc.net.0.link = br0 lxc.rootfs.path = /dev/vmdata-vg/lxc-jessie lxc.rootfs.options = subvol=@ lxc.mount.fstab = /var/lib/lxc/jessie/fstab lxc.tty.max = 4 lxc.pty.max = 1024 lxc.arch = amd64 lxc.uts.name = jessie lxc.cap.drop = sys_module mac_admin mac_override sys_time I have a suspicion that it might ignore lxc.rootfs.options and tries to mount the root BTRFS volume directly and can't find /sbin/init there. I found the following lines of interest in the log.
