Sure it is. Well, kindof :)

Did your search brought you to
http://wiki.1tux.org/wiki/Lxc/Installation/Guest/Centos/6 ? :D

If yes, that guide assumes you have a "working" centos 6 setup
already, in the form of one created using "yum install --installroot".
You could change that to "a filesystem-level backup of a working
centos installation", and pretty much do the same modifications. In
particular, lxc-sysinit.conf and fstab.

There might be other modifcations required (I forgot which ones, try
looking at http://wiki.1tux.org/wiki/Centos6/Installation/Minimal_installation_using_yum#Post-install_configuration
and see which ones is relevant), just try it and see how it goes.

As usual, create backups before you modify anything. Just in case.
