Libvirt 관리 "논리적" 스토리지 풀의 볼륨에 대한 스토리지 볼륨 암호화

"논리적" 풀 유형(예: LVM)에 있는 볼륨에 대해 암호화된 저장소 볼륨(libvirt로 관리)을 생성하는 방법을 모르겠습니다.

# 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

어떤 예가 있습니까? 바라보다http://libvirt.org/formatstorageencryption.html

내 현재(일반 텍스트) 볼륨 및 풀입니다.
