当我使用打包程序构建 win7 盒子时，它会挂起，等待 SSH 可用：

有解决这个问题的经验吗？
答案1
Packer 当前要求在客户操作系统（虚拟机）中安装并运行 SSH 服务器。
编辑 Autounattend.xml 并添加安装 OpenSSH 的命令。确保它是最后一个命令，并且顺序正确。

有关安装 OpenSSH 的示例命令和脚本，请参阅https://github.com/joefitzgerald/packer-windows/blob/master/answer_files/7/Autounattend.xml和https://github.com/joefitzgerald/packer-windows/blob/develop/scripts/openssh.ps1
