[openstack-dev] Why nova mounts FS for LXC container instead of libvirt?

Libvirt can create loop or nbd device for LXC container and mount it by 
itself, for instance, you can add something like this to xml config:

<filesystem type='file'>
  <driver type='loop' format='raw'/>
  <source file='/fedora-20-raw'/>
  <target dir='/'/>

But nova mounts filesystem for container by itself. Is this because rhel-6 
doesn't support filesystems with type='file' or there are some other reasons?
