suspend/resume 后 GCP VM 无响应 - 损坏的启动磁盘或 DHCP 配置

Question

我最近在 GCP 中暂停了一个 VM。几天后，我恢复了，但是无论如何都连接不上实例

使用指向外部IP的ping命令，我没有得到任何回应。当然，使用网络浏览器发送 HTTP 请求也不行。

如果我尝试使用 SSH 连接（使用 gcloud 或浏览器 window），我会遇到连接超时 (Putty) 或 Code: 4003 Reason: failed to connect to backend。我确实尝试再次编辑显式添加 SSH public 密钥到 VM 设置。另外，我有一个用于不同环境的虚拟机，我从未暂停过，也没有发布连接。

我检查了防火墙规则，似乎一切正常。

如果我启用并连接到串行控制台，我会看到它不断地记录这些奇怪的消息：

我已经看到一些 SSH 出现问题的线程，但这似乎是引导磁盘或 DHCP 配置的某种错误。

Answer 1

为了防止有人遇到同样的问题，我现在通过在我的 VM 上执行 RESET 操作解决了这个问题。

在努力找出（未成功）适合此问题的解决方案后，我认为这将是更简单的解决方案，尤其是要记住我的虚拟机处于挂起状态。
