VirtualBox虚拟机CentOS安装增强功能Guest Additions

  • 目前搬瓦工IP被封非常多,建议使用Vultr,充5刀美5刀,按小时计费,IP随时换---点击注册送5刀
  • 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1024×768;

  • 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

        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.
        Creating user for the Guest Additions.
        Creating udev rule for the Guest Additions kernel module.
    

    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
    
        Verifying archive integrity… All good.
