在使用Oracle VM VirtualBox虚拟机安装centos-7.box的时候出现了各种问题，我大概除了的15个小时才解决掉。
开始为了防止兼容性的问题，我都使用了教程中的版本，其实这一步注定了错误的结局。
一些列的错误，各种方式都解决了，但最后还是青色的信息出不来。虚拟化，ssh等，本机都是没问题的。虚拟机连接方式，IP地址多次更改也是ping不通。
最后就一个办法下载最新版的程序包，问题解决了。
CentOS-7-x86_64-Vagrant-2004_01.VirtualBox .box
vagrant_2.2.10_x86_64.msi
VirtualBox-6.1.12-139181-Win.exe
如果使用vagrant up方式下载不下来，只能在url中下载了，和网络有关的，我在10小时内下载了很多次，就一次成功的。
由于在本地安装，且便于安装，我将CentOS-7-x86_64-Vagrant-2004_01.VirtualBox .box放入一个文件夹内，并且改名字为centos-7.box。
盒子位置如图：
红框的文件是后生成的，先不必管它。
vagrant安装位置【这个在哪其实无所谓】：
然后执行下面的红色代码就能安装成功了。
其他博主说的哪些安装方式我都没成功，这是很多次失败得到的结果。
切记，如果没有安装成功，要从第一步vagrant开始安装【也许是我电脑特殊吧】，如果不这么做有时候会报其他错误。
有的错误信息记不清了，但是网上解决方案很难找，我将解决位置和方法记下来。
根据自己的安装路径去找VBoxDrv.inf文件。
我的如下：
D:\Program Files\Oracle\VirtualBox\drivers\vboxdrvVBoxDrv.inf
找到后鼠标右键——安装
这样可以清除一些错误提示。

vagrant 常用命令
启动
vagrant up
退出
vagrant halt
重启
vagrant reload
如果不使用命令，有时候虚拟机会报错坏掉😔
