I can't figure out how to make encrypted storage volume (managed by libvirt) for a volume which sits on 'logical' pool type (ie. on LVM).

# virsh vol-create ocz-5ef92v58m9be7jo9 /tmp/in
error: Failed to create vol from /tmp/in
error: unsupported configuration: storage pool does not support encrypted volumes

Any example? See http://libvirt.org/formatstorageencryption.html

My current (plaintext) volume and pool.
