vagrant 调用 VirtualBox - 无法控制串行端口原始文件值

Question

好的，我先简单解释一下这个问题是什么，然后再解释为什么这是一个问题。

我使用 Vagrant 启动bionic64虚拟机。启动后，会在根目录中创建一个名为ubuntu-bionic-18.04-cloudimg-console.log

但在 VirtualBox 中，串行端口的设置包含绝对路径。我可以vagrant halt将其更改为

./ubuntu-bionic-18.04-cloudimg-console-ci4.log

但当我 时vagrant up，设置已恢复，文件名仍然相同。我该如何修复此问题，或者什么会覆盖此问题？

为什么这是一个问题

打包盒子并尝试分发它，该绝对路径仍然存在，但在目标计算机中不存在。这使得无法共享盒子。

哦，还有 Vagrantfile。

Answer 1

我找到了解决该问题的答案和顺序。

• 我无法更改串行端口 RawFile #0 的绝对路径，我无法在虚拟机运行时更改它，因为 VirtualBox 不允许这样做
• 我可以在不在 VirtualBox 中运行时更改它，但如果流浪汉启动虚拟机时，它会自动将该值覆盖为Vagrantfile根目录的绝对路径
• 这对于清晰起见是有意义的，但当我在运行的盒子上执行此操作时它也会留在盒子里vagrant package（我相信它必须正在运行）。

解决方案如下：

• 在虚拟机未运行时，打开 VirtualBox，并将文件路径和名称更改为./your-file-name
• 然后在 VirtualBox 中启动虚拟机，而不是使用vagrant up
• （可选）vagrant ssh如果您需要从命令行设置任何所需的运行状态。
• 注销并运行vagrant package。文件路径和名称将按照您命名的方式导出！

这个故事并没有完美地结束，因为我想知道我的文件./my-custom-file会放在哪里。结果发现，对于我的 Vagrant 安装，在 Vagrant 的大脑中，它位于/Applications文件夹中。我本以为路径会在 Vagrant 程序的根目录或子文件夹中，或者在特定框的文件夹中。可能有一个$PATH可以使用的设置，但目前这有效（在 Mac 之间，可能在 Windows 中也有效）。
