求助，VirtualBox不能建立虚拟系统？

我是Fedora 14
我安装了这个，用yum   ，VirtualBox-OSE.i686                 3.2.10-1.fc14 ，但是不能建立虚拟系统啊，下面是提示

我安装的是这个系统CentOS-5.5-i386-LiveCD-Release2。iso，光盘安装fedora也不能用


Kernel driver not installed (rc=-1908)

The VirtualBox Linux kernel driver (vboxdrv) is probably not loaded.

If you installed or VirtualBox OSE package recently you need to restart the computer for the driver to load.

Alternatively, you may attempt to load the driver by issuing the following command with system administrator (root) privileges:

'/etc/sysconfig/modules/VirtualBox-OSE.modules'



不能为虚拟电脑 centos5.5 打开一个新任务.
The virtual machine 'centos5.5' has terminated unexpectedly during startup with exit code 1.

Kernel driver not installed (rc=-1908)

我输入/etc/sysconfig/modules/VirtualBox-OSE.modules，显示如下信息，那我应该怎么做才能使用这个程序呢

ERROR: modinfo: could not find module vboxdr
ERROR: modinfo: could not find module vboxnetflt
ERROR: modinfo: could not find module vboxnetadp

sudo yum list virtualbox
已安装的软件包
VirtualBox-4.0.i686         4.0.0_69151_fedora14-1 @/VirtualBox-4.0-4.0.0_69151_fedora14-1.i686
可安装的软件包
VirtualBox-OSE.i686         3.2.10-1.fc14          rpmfusion-free-updates      
VirtualBox-OSE-devel.i686   3.2.10-1.fc14          rpmfusion-free-updates      
VirtualBox-OSE-guest.i686   3.2.10-1.fc14          rpmfusion-free-updates      
VirtualBox-OSE-kmodsrc.i686 3.2.10-1.fc14          rpmfusion-free-updates   

不知道这个OSE是干什么的，我只安装了VirtualBox，没有安装VirtualBox-OSE，所以上面缺少的东西不是太了解

经过搜索，知道了OSE就是 "Open Source Edition" ，开放源代码版本。
另外我是从官方网站上下载了rpm包安装的4.0版本。

检查一下你是否安装了kernel对应的开发包kernel-headers和kernel-devel。virtualbox需要
他们生成对应的内核模块。
像我的这样：
kernel-devel-2.6.35.11-83.fc14.x86_64
kernel-2.6.35.11-83.fc14.x86_64
kernel-headers-2.6.35.11-83.fc14.x86_64

centos用KVM虚拟太好用了。比那个好用。
