Yeah, creating RH/centos on Ubuntu/Debian is quite a hassle. Try mine:
https://github.com/fajarnugraha/lxc/blob/centos-template/templates/lxc-centos.in

After trying several methods, I found the best method to work around
rpm issue is by invoking yum twice: once using the Ubuntu hosts's yum
command (which results in broken rpmdb version and locations), and the
next one using the newly-created-rootfs' yum (which will create a
"correct" rpm database). The downloaded rpm files are preserved
between runs (copied, to be exact), so there's no extra bandwidth used
for the second yum process.

The script is pretty much self-explatanory, so if you want to just
pick some parts of it, feel free to do so.
