在使用Oracle VM VirtualBox虛擬機安裝centos-7.box的時候出現了各種問題，我大概除了的15個小時才解決掉。
開始爲了防止兼容性的問題，我都使用了教程中的版本，其實這一步註定了錯誤的結局。
一些列的錯誤，各種方式都解決了，但最後還是青色的信息出不來。虛擬化，ssh等，本機都是沒問題的。虛擬機連接方式，IP地址多次更改也是ping不通。
最後就一個辦法下載最新版的程序包，問題解決了。
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方式下載不下來，只能在url中下載了，和網絡有關的，我在10小時內下載了很多次，就一次成功的。
由於在本地安裝，且便於安裝，我將CentOS-7-x86_64-Vagrant-2004_01.VirtualBox .box放入一個文件夾內，並且改名字爲centos-7.box。
盒子位置如圖：
紅框的文件是後生成的，先不必管它。
vagrant安裝位置【這個在哪其實無所謂】：
然後執行下面的紅色代碼就能安裝成功了。
其他博主說的哪些安裝方式我都沒成功，這是很多次失敗得到的結果。
切記，如果沒有安裝成功，要從第一步vagrant開始安裝【也許是我電腦特殊吧】，如果不這麼做有時候會報其他錯誤。
有的錯誤信息記不清了，但是網上解決方案很難找，我將解決位置和方法記下來。
根據自己的安裝路徑去找VBoxDrv.inf文件。
我的如下：
D:\Program Files\Oracle\VirtualBox\drivers\vboxdrvVBoxDrv.inf
找到後鼠標右鍵——安裝
這樣可以清除一些錯誤提示。

vagrant 常用命令
啓動
vagrant up
退出
vagrant halt
重啓
vagrant reload
如果不使用命令，有時候虛擬機會報錯壞掉😔
