Hi, I also got this problem on a Kernel without CONFIG_USER_NS (3.10.9-1-zen), so it's _not_ user namespace related.
You can easily reproduce this by doing the following: Create some "base image" (I did with pacstrap, but every "linux for a chroot with a /sbin/init inside" should work) Create a cow directory Create an aufs mountpoint mount -t aufs none /path/to/root -o br=/path/to/cow=rw:/path/to/base_image=ro Create the lxc container inside libvirt (easy to do with virt-manager) Start the container Power off the container Now try to touch files inside /path/to/root. you get EROFS.
