引用: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.
解决的方法就是给系统安装module-assistant模块，执行：
sudo apt-get install module-assistant
然后加载：
sudo modprobe vboxnetflt
至此，问题解决，在linux下使用VirtualBox尽情的虚拟XP系统吧。
