That's expected and correct. Libvirt does not use lxc tools to manage
Linux containers. Libvirt manages everything by itself and talks to the
kernel directly. Thus containers created in libvirt are not visible to
lxc tools and containers created using lxc tools are not visible to
libvirt. In other words, use either lxc tools or libvirt but do not try
to mix them.

If you want to manage libvirt's containers from a command line, use
virsh. For example, "virsh list --all" will show you all containers
libvirt knows about.
