環境：
Win10 安裝 VBox（6.1.10），虛擬機系統為：Centos8
開始：
http://download.virtualbox.org/virtualbox 中找到你的VBox版本下載對應版本：
后面以為的版本為例：
http://download.virtualbox.org/virtualbox/6.1.10/
下載：VBoxGuestAdditions_6.1.10.iso 文件
關閉你的 虛擬機系統為：Centos8
VBox->設置->存儲->控制器->添加虛擬光驅->注冊->"選擇VBoxGuestAdditions_6.1.10.iso" ->選擇
系統和虛擬機復制，如下設置也設置一下，不知道有沒有作用
開啟Centos8:
mkdir /mnt/cdrom sudo mount /dev/cdrom /mnt/cdrom #加載虛擬光盤 sudo umount /dev/cdrom /mnt/cdrom #掛載虛擬光盤 cd /mnt/cdrom ./VBoxLinuxAdditions.run
上面執行可能會碰到問題
#將所有組件更新到最新
yum -y groupinstall "Development Tools"
yum install update
yum update kernel
yum update kernel-devel
yum install kernel-headers
yum install gcc*
yum install gcc make
reboot
問題1
Building the main Guest Additions 6.1.10 module for kernel 4.18.0-193.6.3.el8_2.x86_64. Error building the module. Build output follows. make V=1 CONFIG_MODULE_SIG= CONFIG_MODULE_SIG_ALL= -C /lib/modules/4.18.0-193.6.3.el8_2.x86_64/build M=/tmp/vbox.0 SRCROOT=/tmp/vbox.0 -j1 modules Makefile:978: *** "Cannot generate ORC metadata for CONFIG_UNWINDER_ORC=y, please install libelf-dev, libelf-devel or elfutils-libelf-devel". Stop. make: *** [/tmp/vbox.0/Makefile-footer.gmk:114: vboxguest] Error 2 modprobe vboxguest failed 上面問題解決方法：https://www.cnblogs.com/mychangee/p/12087954.html 1. 安裝kernel-devel，並將kernel和kernel-devel更新至同一版本 # yum install -y kernel-devel gcc //安裝kernel-devel和gcc編譯工具鏈 # yum -y upgrade kernel kernel-devel //更新kernel和kernel-devel到最新版本 # reboot //重啟，重啟時，選擇最新版本的內核啟動 2. 以新版本內核啟動，並刪除舊版本內核 //啟動之后 # uname -r //查看當前啟動的內核版本 # rpm -qa | grep kernel-[0-9] //查看全部的內核 # yum remove 舊版本內核 //刪除舊版本內核 完成之后，就可以繼續安裝virtualbox增強工具了。
問題2：
"CANNOT GENERATE ORC METADATA FOR CONFIG_UNWINDER_ORC=Y, PLEASE INSTALL LIBELF-DEV, LIBELF-DEVEL OR ELFUTILS-LIBELF-DEVEL". STOP.
未找到“libelf-dev 或 elfutils-libelf-devel”
yum install elfutils-libelf-devel
成功返回如下：

大功造成現在使用真爽！
