升级 VirtualBox 后 Vagrant 无法启动

近期将本地安装的 VirtualBox 升级到 7.1 版本，昨天启动开发环境时时发现 Vagrant 2.4.1 不支持 VirtualBox 7.1，错误提示如下：

The provider 'virtualbox' that was requested to back the machine
'xxxxyyyyyzzzz' is reporting that it isn't usable on this system. The
reason is shown below:

Vagrant has detected that you have a version of VirtualBox installed
that is not supported by this version of Vagrant. Please install one of
the supported versions listed below to use Vagrant:

4.0, 4.1, 4.2, 4.3, 5.0, 5.1, 5.2, 6.0, 6.1, 7.0

A Vagrant update may also be available that adds support for the version
you specified. Please check www.vagrantup.com/downloads.html to download
the latest version.

看起来 Vagrant 2.4.1 最高支持到 7.0 版本的 VirtualBox。如果要等 Vagrant 更新版本还不知道要到猴年马月，将 VirtualBox 退回到 7.0 版本也怕把开发环境弄坏。好在只要稍稍动一下手脚就能让 Vagrant 支持 VirtualBox 7.1 了。

修改 Vagrant 安装目录下的 embedded\gems\gems\vagrant-2.4.1\plugins\providers\virtualbox\driver\meta.rb 文件，在第 71 行下新增如下一行代码：

ruby          driver_map   = {
            "4.0" => Version_4_0,
            "4.1" => Version_4_1,
            "4.2" => Version_4_2,
            "4.3" => Version_4_3,
            "5.0" => Version_5_0,
            "5.1" => Version_5_1,
            "5.2" => Version_5_2,
            "6.0" => Version_6_0,
            "6.1" => Version_6_1,
            "7.0" => Version_7_0,
            "7.1" => Version_7_0,
          }

保存后再次启动 Vagrant，顺利骗过了程序，VirtualBox 虚拟机正常启动了。
