登陸到節點：

修改了bcec162節點的/etc/libvirt/qemu.conf文件:
# The user ID for QEMU processes run by the system instance
user = "root"
# The group ID for QEMU processes run by the system instance
group = "root"

# Set to 0 to disable file ownership changes.
#dynamic_ownership = 0
bcec162節點遷移到node153節點成功。

# The user ID for QEMU processes run by the system instance
#user = "root"
# The group ID for QEMU processes run by the system instance
#group = "root"

error: Failed to restore domain from checkpoint
error: internal error process exited while connecting to monitor: qemu: could not open disk image /one_images_3.8.1/0/43/disk.0: Permission denied
將/etc/libvirt/qemu.conf文件中注釋掉dynamic_ownership=0，開啟user=root和group=root.
如果開啟dynamic_ownership則恢復虛擬機也會報出上面的錯誤信息。
在node152節點上恢復虛擬機：
[root@node152 43]# virsh restore checkpoint
Domain restored from checkpoint
[root@node152 43]# virsh list
