# virsh保存和恢复虚拟机状态 在解决[KVM虚拟机vnc远程访问鼠标偏移修复](https://github.com/huataihuang/cloud-atlas-draft/tree/6f3204fffc11cf006abd394631e2598d98b415c3/virtual/kvm/startup/in_action/kvm_vnc_mouse/README.md)问题时，修改了libvirt的xml配置，需要重启一次Windows虚拟机。 尝试采用save/restore方式恢复运行Windows虚拟机： * 首先暂停虚拟机运行 ``` #virsh suspend win2016 Domain win2016 suspended ``` * 检查win2016虚拟机运行状态 ``` #virsh list Id Name State ---------------------------------------------------- ... 9 win2016 paused ``` * 保存虚拟机到文件： ``` #virsh save win2016 win2016.status Domain win2016 saved to win2016.status ``` * 当虚拟机保存到文件之后，可以看到虚拟机立即恢复了running状态（此时 **没有** 执行`virsh resume win2016`） ``` #virsh list Id Name State ---------------------------------------------------- ... 9 win2016 running ``` * 销毁运行中虚拟机 ``` #virsh destroy win2016 Domain win2016 destroyed ``` * 从存储的状态文件恢复虚拟机 ``` #virsh restore win2016.status Domain restored from win2016.status ``` * 此时恢复的虚拟机是保存时候的`paused`状态 ``` #virsh list Id Name State ---------------------------------------------------- 11 win2016 paused ``` * 恢复虚拟机运行 ``` #virsh resume win2016 Domain win2016 resumed ``` > 检查发现这种save/restore方式不能使得鼠标偏移立即解决，还是需要在虚拟机操作系统内部重启一次虚拟机才生效。 --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
