红帽全球峰会13.2. 克隆卷
新卷将从与要克隆的卷相同的存储池中分配。 virsh vol-clone 必须具有
--pool 参数，该参数指明要克隆包含卷的存储池的名称。命令的其余部分命名要克隆的卷(volume3)和已克隆的新卷的名称(clone1)。virsh vol-list 命令列出存储池中存在的卷(guest_images_disk)。
# virsh vol-clone --pool guest_images_disk volume3 clone1
Vol clone1 cloned from volume3
# virsh vol-list guest_images_disk
