Hi Guido,

Can you be more specific about how to use a image file to limit disk size
but with no loop device?

All I know is something like this:
# dd if=/dev/zero of=lxc.img bs=1M count=0 seek=40960
# mkfs.ext3 lxc.img
# mount -o loop lxc.img /lxc_container1/       # here we need loop device
# cp -r /template1/rootfs/* /lxc_container1/

Thanks!
Qiang
