GCE - 我們無法連接到端口22上的VM

當我嘗試通過SSH連接到Google Compute Engine上的實例時出現以下錯誤。GCE - 我們無法連接到端口22上的VM

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

步驟我沒有使用Ubuntu的模板來得到這個錯誤

創建一個新的實例。
通過SSH連接並安裝了所有我需要的應用程序。
刪除實例，但在刪除實例時不刪除引導磁盤。
使用已刪除實例的啓動盤創建新的自定義映像。
使用自定義圖像啓動了一個新實例。
單擊GCE控制檯上的SSH鏈接。

這是實例的串行控制檯輸出。

所以我的問題是我如何可以通過SSH連接到我的情況下，如何確保當我創建一個新的自定義圖像也不會再次發生。

謝謝。

你確定你的服務器正在運行嗎？似乎有掛載磁盤的問題：'內核恐慌 - 不同步：VFS：無法在未知塊（0,0）上掛載根fs' –

您是否在安裝應用程序時修改了fstab文件？如果是這樣，創建一個受影響的磁盤作爲次要附加的全新實例，您可以檢查日誌並修改什麼是壞的 – George

重新啓動您的實例。它與我一起工作。
