在安装虚拟机时会出现
Kernel driver not installed (rc=-1908)
The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv. Re-setup the kernel module by executing
'/etc/init.d/vboxdrv setup'
as root. Users of Ubuntu, Fedora or Mandriva should install the DKMS package first. This package keeps track of Linux kernel changes and recompiles the vboxdrv kernel module if necessary.
运行如下命令即可解决：
sudo aptitude update
sudo aptitude install dkms
sudo /etc/init.d/vboxdrv setup
