安装VirtualBox后，vboxadd服务启动失败

提示失败

Building the VirtualBox Guest Additions kernel modules [FAILED]

Your system does not seem to be set up to build kernel modules.

Look at /var/log/vboxadd-install.log to find out what went wrong.

Once you have corrected it, you can run /etc/init.d/vboxadd setup to build them.

more /var/log/vbox-install.log 内容

Makefile:183: *** Error: unable to find the sources of your current Linux kernel. Specify KERN_DIR=<directory> and run Make ag

ain. Stop.

安装GCC

#yum install gcc

# yum install gcc kernel-devel kernel-headers

重启系统或重新安装virtrualbox 再或者

export KERN_DIR=/usr/src/kernels/2.6.18-164.15.1.el5-i686/(2.6.18-164.15.1.el5-i686可查看自己机器就具体位置而知)

最后，/etc/init.d/vboxdrv setup即可。
