打包程序 ssh 超时

Question

我正在尝试在 jenkins 管道中使用 packer 构建映像。但是，打包程序 ssh 配置器不起作用，因为 ssh 永远不会可用，并且因超时而出错。对该问题的进一步调查表明，映像缺少/etc/sysconfig/network-scripts 目录中的网络接口文件 ifconfig-eth0，因此它永远不会获得 ip 并且不接受 ssh 连接。问题是，有很多这样的图像要生成，我无法在 virtualbox 的 GUI 中手动打开每个图像并纠正问题并重新打包。还有其他可能的解决方案吗？

如果在预配过程中不需要 SSH 连接，可以将其关闭。请参阅有关通信器的打包程序文档，您可以在none看到在主机和来宾之间切换通信的选项。
