Packer等待SSH连接

Question

我是一名新手，正在学习使用Packer。我已经详细研究了上面提到的问题。我目前正在尝试创建一个Ubuntu 32位虚拟机，在Windows 10操作系统上运行Packer。当安装完成并且虚拟机重启后，在我的虚拟机上出现GUI登录提示时，Packer仍在运行，而我的主机Windows显示正在等待SSH可用。如何最好地启用ssh以供Packer用于连接我的虚拟机。以下是我的json.template：

附言：是的，在来这里问问题之前，我已经查看过模板了。

也附上预设文件。 - Rickard von Essen

很遗憾，我没有权限这样做。文件里面可能有什么问题需要我去查看吗？ - Sam

Answer 1

实际上，我明白了。这是设置ssh_port为22、将ssh_address设置为我的虚拟机地址、将ssh_skip_nat_mapping设置为true以及将我的网卡从内部网络更改为仅主机，并进行配置的组合。

Answer 2

您覆盖了打包程序的网络设置，因此主机将无法访问客户端。要解决此问题，请删除以下两行：

[ "modifyvm", "{{.Name}}", "--nic1", "intnet"], 
[ "modifyvm", "{{.Name}}","--nic2", "null"],
