You are misunderstanding the referenced thread. It isn't about
available features in libvirt. In this thread Evgeniy suggests several
additions to libvirt domain XML format related to OpenVZ.

The additions of quota control to the filesystem element have never
been implemented, so they are not available and you're just seeing
expected behavior.
