现象
erika@velvet:/etc/init.d$ sudo virtualBox setup WARNING: The character device /dev/vBoxdrv does not exist. Please install the virtualBox-ose-dkms package and the appropriate headers,most likely linux-headers-generic. You will not be able to start VMs until this problem is fixed.
原因分析：
发现是linux-header安装的版本不对。linux-header是kernel头文件，头文件不对，编译的ko不对，ko不对，就没法安装上。
怎么发现的？在执行下面的修改方法时报告linux-kernel headers对应的版本不是想要的版本，因而觉察。
868 sudo apt-get update && sudo apt-get install linux-headers-`uname -r`
869 sudo apt-get install --reinstall virtualBox
870 sudo apt-get install --reinstall virtualBox-dkms
