Google compute engine 自动迁移后如何处理断开的实例

这与在Google Compute Engine中调试VM有关：

在基于Google的操作“自动迁移实例”之后，一个长时间运行的实例似乎变得不可访问。是否有方法或手段对此进行调试？重新启动实例，尝试使用浏览器中的SSH连接（或直接连接）意味着两者都失败。状态将实例显示为在加载时消耗CPU，然后基本处于平坦状态

似乎实例本身永远无法访问。这是为其他人准备的吗？是否有一个简单的状态页面来查看实例是否已损坏或这是否是服务中断

自动迁移发生在2014年8月25日，这很可能是由谷歌作为计划（或非计划）维护的一部分触发的

更新：在三个小时无法连接后，网络问题得到解决。我没有找到状态页面，也没有看到任何关于停机的内容。

从命令行查看控制台输出：

gcloud compute instances get-serial-port-output NAME [--project PROJECT_ID] [--zone ZONE]

（其中名称、项目ID和区域与您的虚拟机匹配） 或来自

（向下滚动至底部并单击“查看控制台”）

这可能会让你明白为什么它不允许你访问它。（我在Apache2中配置了一个加密的SSL服务器证书，它在引导时需要密码，但VM的控制台不是交互式的。它是只读的。我必须删除我的VM，但保留我的引导磁盘，将该引导磁盘装载到另一个VM上，找到证书文件并将其转换为未加密的，然后卸载第二个磁盘并创建一个n。）ew虚拟机使用现在的固定引导磁盘。工作起来很有魅力。当然，你的虚拟机可能会抱怨一些不同的事情。）

也有同样的问题，我的实例死了两天（不可能使用SSH）。必须手动关闭并重新启动

背景：容器VM映像（用于运行docker）；外部硬盘连接
