【请教VirtualBox问题】虚拟机与物理机共享文件

不能为虚拟电脑admin 打开一个新任务.

Virtual machine 'admin' has terminated unexpectedly during startup.

Kernel driver not installed (rc=-1908)

返回 代码:
NS_ERROR_FAILURE (0x80004005)
组件:
Machine
界面:
IMachine {99404f50-dd10-40d3-889b-dd2f79f1e95e}


Kernel driver not installed (rc=-1908)

Please install the virtualbox-ose-dkms package and execute 'modprobe vboxdrv' as root.

根据网上的解决方法
sudo aptitude update
sudo aptitude install dkms
sudo /etc/init.d/vboxdrv setup
问题还是出现,～～
