用下面命令安装：
sudo apt-get install virtualbox-ose virtualbox-ose-source
新建一个虚拟机器，运行时出现下面这个错误：
VirtualBox kernel driver not installed. The vboxdrv kernel module was either not loaded or /dev/vboxdrv was not created for some reason. Re-setup the kernel module by executing '/etc/init.d/vboxdrv setup' as root.
VBox status code: -1908 (VERR_VM_DRIVER_NOT_INSTALLED).
Result Code: 0x80004005
Component: Console
Interface: IConsole
说是vboxdrv内核模块没有安装。
解决方法：
sudo apt-get install linux-headers-`uname -r`
sudo m-a prepare
sudo m-a -f auto-install virtualbox-ose-source
sudo adduser `whoami` vboxusers
重启机器。
