VirtualBox虚拟机CentOS安装增强功能Guest Additions

转自简书

没有安装Virtual Box增强功能Guest Additions的虚拟机操作很不方便,比如:

  • 虚拟机的分辨率最大只有1024x768;
  • 鼠标被虚拟机捕获后要按右Ctrl键才能释放,否则只能再虚拟机里移动;
  • 剪贴板不能共享

安装Guest Additions可以解决上述所有问题。
以CentOS 7.3虚拟机为例,如果安装CentOS时没有选择Development Tools组,需要先安装kernel-devel和gcc
$ sudo yum install -y kernel-devel gcc

通过VirtualBox的 设备 | 安装增强功能... 菜单可以加载VBoxGuestAdditions.iso,可以直接点击Run安装或者执行
$ cd /run/media/centos/VBOXADDITIONS_5.1.22_115126
$ sudo sh ./VBoxLinuxAdditions.run

有时安装会出错

vboxadd.sh: Starting the VirtualBox Guest Additions.
Failed to set up service vboxadd, please check the log file
/var/log/VBoxGuestAdditions.log for details.

查询log发现是找不到和Linux内核匹配的源文件
$ cat /var/log/VBoxGuestAdditions.log

vboxadd.sh: failed: Look at /var/log/vboxadd-install.log to find out what went wrong.
vboxadd.sh: failed: Look at /var/log/vboxadd-install.log to find out what went wrong.
vboxadd.sh: failed: modprobe vboxguest failed.

$ cat /var/log/vboxadd-install.log

/tmp/vbox.0/Makefile.include.header:112: *** Error: unable to find the sources of your current Linux kernel. Specify KERN_DIR= and run Make again. Stop.

查询kernel-devel版本是3.10.0-514.26.2.el7.x86_64,而Linux内核版本是3.10.0-514.el7.x86_64,确实不一致。如果安装CentOS时选择了Development Tools组,kernel-devel版本和Linux内核版本是匹配的,则不会出现这个问题。
$ rpm -qa | grep kernel-devel

kernel-devel-3.10.0-514.26.2.el7.x86_64

$ uname -r

3.10.0-514.el7.x86_64

可以使用下面两个命令中的一个安装和Linux内核版本匹配的kernel-devel
$ sudo yum install -y "kernel-devel-uname-r == $(uname -r)"
$ sudo yum install -y kernel-devel-3.10.0-514.el7
然后再次安装Guest Additions成功
$ cd /run/media/centos/VBOXADDITIONS_5.1.22_115126
$ sudo sh ./VBoxLinuxAdditions.run
