Sometimes it's the "I want to make a small change, it should still
work"-stuff that's giving you a headache. Seriusly :)

I'm guessing you create a btrfs subvolume vor the container? If yes,
check it's permission. By default, the new subvolume will only be
accessible to root. A simple "chmod 755" should fix it.
I'm using btrfs subvols as well, but in my case /var/lib/lxc itself is
a subvol, and the containers have their own subvols under it.
