ubuntu 下virtualbox 启动时Kernel driver not installed (rc=-1908) 错误的解决方法

Kernel driver not installed (rc=-1908) 

The VirtualBox Linux kernel driver (vboxdrv) is either not loadedor there is a permission problem with /dev/vboxdrv. Re-setup thekernel module by executing 

'/etc/init.d/vboxdrv setup' 

as root. Users of Ubuntu, Fedora or Mandriva should install theDKMS package first. This package keeps track of Linux kernelchanges and recompiles the vboxdrv kernel module ifnecessary. 

解决方法：

sudo aptitude update 
sudo aptitude install dkms 
sudo /etc/init.d/vboxdrv setup 

提示：Stopping VirtualBox kernelmodule                       
             Recompiling VirtualBox kernel module 
             Starting VirtualBox kernel module 
就可以了。
