我的自动安装功能可以正常工作。但是 - 我尝试在非 EFI 机器（本例中为 VM）上执行此操作，但无法正常工作 - 我只看到语言选择屏幕。
我的引导行是：

它从不要求用户数据文件???
我做错了什么，导致自动安装启动？
答案1
我认为这行
cloud-config-url=http://MyIp/autoinstall/meta-data
应该：
cloud-config-url=http://MyIp/autoinstall/user-data
正如您所说，您的元数据为空，而用户数据包含云配置。至少这解决了我设置中的类似问题。希望这能有所帮助 :)
答案2
我在使用 20.04.3 时遇到了其他问题，但是我发现您的启动行中有一个拼写错误：
‘ds=nocloud-net;s=http://MyIP/autoinstall/’应该ds=nocloud-net;s=http://MyIP/autoinstall/
