fc5安装virtualbox出错

可可熊

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 {1dea5c4b-0753-4193-b909-22330f64ec45}


按装网上找到的解决办法使用：sudo modprobe vboxdrv

结果：
[cocobear@cocobear ~]$ sudo modprobe vboxdrv
FATAL: Error inserting vboxdrv (/lib/modules/2.6.20-1.2316.fc5/misc/vboxdrv.ko): Invalid module format

这是怎么回事，有什么解决办法？
