Building the VirtualBox Guest Additions kernel modules

The headers for the current running kernel were not found. If the following

module compilation fails then this could be the reason.
The missing package can be probably installed with

yum install kernel-devel-2.6.32-431.el6.x86_64

解决方法：

1）安装 gcc make gcc-c++

#yum install gcc make gcc-c++

2）安装kernel-headers kernel-devel
#yum install kernel-headers kernel-devel
3）、如果还不行，就把centos所有包升级下

#yum update
4）、重启

#reboot
5）、重新安装

# mount -t auto /dev/cdrom /mnt/cdrom
#sh ./VBoxLinuxAdditions.run

PS:访问共享文件夹

重启之后，centos就可以访问Windows/mac提供的共享文件夹了。
mkdir /mnt/share   新建挂载点（mountpoint）
mount -t vboxsf mysharedir /mnt/share   挂载共享文件夹   ------------------mysharedir
是虚拟机中设置的共享文件夹名称
cd /mnt/share   进入共享文件夹
ls   看看有什么
