Virtual Box 中 安装 VBox Guest Additions扩展程序

环境：

Win10 安装 VBox（6.1.10），虚拟机系统为：Centos8

开始：

http://download.virtualbox.org/virtualbox  中找到你的VBox版本下载对应版本：

后面以为的版本为例：

http://download.virtualbox.org/virtualbox/6.1.10/ 

下载：VBoxGuestAdditions_6.1.10.iso 文件

关闭你的 虚拟机系统为：Centos8

 

 

 

 

 

 

 

 

 VBox->设置->存储->控制器->添加虚拟光驱->注册->"选择VBoxGuestAdditions_6.1.10.iso" ->选择

系统和虚拟机复制，如下设置也设置一下，不知道有没有作用

 

 

 

 开启Centos8:

mkdir /mnt/cdrom

sudo mount /dev/cdrom /mnt/cdrom #加载虚拟光盘
sudo umount /dev/cdrom /mnt/cdrom  #挂载虚拟光盘

cd /mnt/cdrom

./VBoxLinuxAdditions.run

 

上面执行可能会碰到问题

 

#将所有组件更新到最新
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

 

问题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

上面问题解决方法：https://www.cnblogs.com/mychangee/p/12087954.html

1. 安装kernel-devel，并将kernel和kernel-devel更新至同一版本
# yum install -y kernel-devel gcc //安装kernel-devel和gcc编译工具链
# yum -y upgrade kernel kernel-devel //更新kernel和kernel-devel到最新版本
# reboot //重启，重启时，选择最新版本的内核启动
2. 以新版本内核启动，并删除旧版本内核
//启动之后
# uname -r //查看当前启动的内核版本
# rpm -qa | grep kernel-[0-9] //查看全部的内核
# yum remove 旧版本内核 //删除旧版本内核
完成之后，就可以继续安装virtualbox增强工具了。

 

问题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：

[root@localhost cdrom]# ./VBoxLinuxAdditions.run

大功造成现在使用真爽！
