title: How to mount a LVM partition within a LVM volume?
body: <p>I have built a VG named cinder-volumes. Within this VG, I created a PV named leader-volume. Then I mounted this PV as the root filesystem of a KVM Ubuntu installation. During the installation process, I selected LVM partition.
  At last, I created a snapshot for the PV leader-volume.
  Now I want to read some files within my Ubuntu installation... What shall I do? </p>
