+KVM/QEMU创建虚拟机快照时，报如下错误：
+
+Operation not supported: internal snapshots of a VM with pflash based firmware are not supported
+
+
+
+
+
+解决办法：
+
+ 1. 进入宿主机，并切入到root用户
+
+ 2. 运行命令“virsh list”，查找虚拟机名称
+
+ 3. 运行命令，编辑虚拟机配置文件
+
+ # virsh edit Test_VirtualMachine_NAME
+
+ 1）搜索关键字“loader”,定位到需要修改字段所在的行
+
+
+
+
+
+ 2）将字段“type=pflash”修改为“type=rom”,保存":wq!"
+
+
+
+
+
+4. 关闭虚拟机：
+
+ # virsh shutdown Test_VirtualMachine_NAME
+
+ 5. 启动虚拟机：
+
+ # virsh start Test_VirtualMachine_NAME
+
+ 6. 查看虚拟机配置文件type，是否已修改为“rom”
+
+ #  virsh dumpxml Test_VirtualMachine_NAME | grep loader
+
+　7. 再次创建虚拟机快照成功！
+
+
+
+Xml 标黄部分把pflash 改成rom
