Have you looked at the download template?

lxc-create -t download -n YOUR_CONTAINER_NAME

You'll get a list of distros/versions to choose:

It will then download the necessary image and do the needed configuration,
without using rpm/apt/whatever-package-management-in-that-OS.


If you have your OWN root image (e.g. dump from a server), then it's a
different story. Look at each template to see what modifications are
needed. For ubuntu, see configure_ubuntu() on
/usr/share/lxc/templates/lxc-ubuntu.
