GCE - 我们无法连接到端口22上的VM

当我尝试通过SSH连接到Google Compute Engine上的实例时出现以下错误。GCE - 我们无法连接到端口22上的VM

Connection Failed. We are unable to connect to the VM on port 22.

步骤我没有使用Ubuntu的模板来得到这个错误

创建一个新的实例。
通过SSH连接并安装了所有我需要的应用程序。
删除实例，但在删除实例时不删除引导磁盘。
使用已删除实例的启动盘创建新的自定义映像。
使用自定义图像启动了一个新实例。
单击GCE控制台上的SSH链接。

这是实例的串行控制台输出。

所以我的问题是我如何可以通过SSH连接到我的情况下，如何确保当我创建一个新的自定义图像也不会再次发生。

谢谢。

你确定你的服务器正在运行吗？似乎有挂载磁盘的问题：'内核恐慌 - 不同步：VFS：无法在未知块（0,0）上挂载根fs' –

您是否在安装应用程序时修改了fstab文件？如果是这样，创建一个受影响的磁盘作为次要附加的全新实例，您可以检查日志并修改什么是坏的 – George

重新启动您的实例。它与我一起工作。
