I think your rootfs is not completely configured.
You should probably check, in the Bodhizazen's blog, the "Configure the 
rootfs" section.

At present, all this stuff is manual, but I am sure we will be able to 
create some scripts to automatically generate these OS templates like 
http://sourceforge.net/apps/trac/lxc-provider/
