unable to load vboxguest kernel module

vbox 安装增强功能失败一例

起因

vbox 从 6.9 升级到 7.1.6，Centos 7 虚拟机里的的共享文件夹设置失效了。尝识重新安装增强功能，报如下错：

[root@vbox cdrom]# ./VBoxLinuxAdditions.run
Verifying archive integrity...  100%   MD5 checksums are OK. All good.
Uncompressing VirtualBox 7.1.6 Guest Additions for Linux  100%

Removing installed version 7.1.6 of VirtualBox Guest Additions...
VirtualBox Guest Additions: Starting.
VirtualBox Guest Additions: Setting up modules
VirtualBox Guest Additions: Building the VirtualBox Guest Additions kernel
modules.  This may take a while.
VirtualBox Guest Additions: To build modules for other installed kernels, run
VirtualBox Guest Additions:   /sbin/rcvboxadd quicksetup <version>
VirtualBox Guest Additions: or
VirtualBox Guest Additions:   /sbin/rcvboxadd quicksetup all

3.10.0-1160.119.1.el7.x86_64.

VirtualBox Guest Additions: Look at /var/log/vboxadd-setup.log to find out what
went wrong
[root@vbox cdrom]# cat /var/log/vboxadd-setup.log
-bash: $'\346cat': command not found
[root@vbox cdrom]# cat /var/log/vboxadd-setup.log
Building the main Guest Additions 7.1.6 module for kernel 3.10.0-1160.119.1.el7.x86_64.
Error building the module.  Build output follows.
make V=1 CONFIG_MODULE_SIG= CONFIG_MODULE_SIG_ALL= -C /lib/modules/3.10.0-1160.119.1.el7.x86_64/build M=/tmp/vbox.0 SRCROOT=/tmp/vbox.0 -j1 modules
arch/x86/Makefile:169: *** CONFIG_RETPOLINE=y, but not supported by the compiler. Compiler update recommended..  Stop.
make: *** [vboxguest] Error 2
[root@vbox cdrom]#

报错日志里有 “Compiler update recommended” 很明显是要升级编译工具。

安装高版本的编译工具

网上查了一下，看上去很 Easy，按下面这个命令就可以安装高版本的编译工具：

yum -y install centos-release-scl centos-release-scl-rh
yum -y install devtoolset-11-gcc devtoolset-11-gcc-c++ devtoolset-11-binutils

Centos 7 官方2024年6月以后就不再提供支持，所以更新 Centos 7 为国内 yum 源。

CentOs-Base.repo 的内容就不贴了，网上很多，照做基本都没有问题。

主要是 CentOS-SCLo-scl.repo 和 CentOS-SCLo-scl-rh.repo 这两个都要改，不要只改一个。

[root@vbox yum.repos.d]# cat CentOS-SCLo-scl.repo
# CentOS-SCLo-sclo.repo
#
# Please see http://wiki.centos.org/SpecialInterestGroup/SCLo for more
# information

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-SIG-SCLo

[root@vbox yum.repos.d]# cat CentOS-SCLo-scl-rh.repo
# CentOS-SCLo-rh.repo

[centos-sclo-rh]

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-SIG-SCLo

修改完成后，重新安装devtoolset ，我这里用 11 的版本。

再次安装增强组件。注意：安装前要执行 scl enable devtoolset-11 bash 使新版的gcc生效。
