Vagrant up失败并发出警告：远程连接断开。重试

升级到vagrant版本2.1.1和最新的centos/7（virtualbox，1803.01）并且$vagrant up现在在加载新密钥后无法生成。正在使用的Vagrant文件在以前版本的Vagrant（2.0.3）上运行良好

有趣的是，我能够使用vagrant手动连接到实例，使用新密钥，既可以使用direct ssh，也可以使用：

$vagrant ssh nat

已尝试的内容：
vagrant config.vm.boot_timeout内的延长超时=1200
在重新安装之前，已卸载vagrant和virtualbox+手动删除插件并删除C:\Users\owner\.vagrand.d和C:\Users\owner\.virtualbox目录
尝试了以前有效的旧版本nat.vm.box_version=“1704.01”

为什么不回滚？
最初我升级了，因为我有另一个问题，我将提出一个单独的线程。一旦我创建了它，就会链接到这里

版本
主机操作系统：Windows 7 Professional
来宾操作系统：centos/7 1803.01

流浪版本：2.1.1

流浪者插件列表：
流浪旅店经理（1.8.8）
流浪宿主（2.8.1）
流浪者proxyconf（1.5.2）
流浪重新装载（0.0.1）
流浪股（1.1.9）
流浪客（0.15.1）

还显示了我的稍微消毒过的流浪汉档案。列出的脚本中没有一个实际运行，因为在执行之前，框失败

nat:检测到不安全的密钥。流浪汉将自动替换
nat：这是一个新生成的密钥对，以提高安全性

每次运行“Vagrant up”命令时，它都会尝试查找不安全的密钥并替换它。要使用路径“config.ssh.private_key_path”中提到的默认密钥，请在Vagrant文件中包含以下条目

---

请在您的Vagrant文件中使用config.ssh.insert_key=false，然后再试一次。

我使用OSX，通过重新启动计算机解决了此问题。

这可以作为注释安全地显示。您能告诉我们Vagrant文件的位置吗？提前谢谢！在Windows上，Vagrant文件的完整路径是：C:\Users\your username\.Vagrant.d\box\laravel Vagrant Slash homestead\9.1.0\virtualbox\Vagrant文件
