需要先将原机关机

root@Server-A7:/etc/libvirt/qemu# virsh shutdown UPF_VM-0819
Domain UPF_VM-0819 is being shutdown

root@Server-A7:/etc/libvirt/qemu# virsh list --all
 Id    Name                           State
----------------------------------------------------
 13    CP_VM-1                        running
 -     UPF_VM-0819                    shut off

开始克隆

# /root/UPF_VM-0819-1.qcow2 会根据原机在克隆过程中自动生成
root@Server-A7:/etc/libvirt/qemu# virt-clone -o UPF_VM-0819 -n UPF_VM-0819-1 --file /root/UPF_VM-0819-1.qcow2
