这与在Google Compute Engine中调试VM有关：
基于Google的操作似乎无法访问长时间运行的实例：“自动迁移实例”。有调试方法或手段吗？重新启动实例，尝试使用浏览器（或直接）通过SSH连接意味着两者都失败。状态显示实例在加载时消耗CPU，然后大部分是平坦的。
似乎实例本身永远无法访问。这是否适合其他人？是否有一个简单的状态页面来查看实例是否被破坏或是否是服务中断？
自动迁移发生在2014-08-25，这可能是由Google作为计划（或计划外）维护的一部分触发的。
更新：在无法连接三个小时后，网络问题得以解决。我没有找到状态页面，也没有看到任何中断。

查尔斯，
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NAME，PROJECT_ID和ZONE与您的VM匹配） 或来自
（向下滚动到底部，然后点击“查看控制台”）。
这可能会让您知道为什么它不允许您访问它。 （我在Apache2中配置了一个加密的SSL服务器证书，它在启动时需要密码短语，但VM的控制台不是交互式的。它是只读的。我必须删除我的虚拟机，但保留我的启动盘，安装启动另一台虚拟机上的磁盘，找到证书文件并将其转换为未加密，然后卸载第二块磁盘并使用现在修复的启动盘创建一个新的虚拟机。工作就像一个魅力。当然，你的虚拟机可能会抱怨不同的东西。）

遇到同样的问题，我的实例已经死了2天（没有SSH可能）。不得不手动关机并重启。
