ubuntu virtualbox启动不了
原文位置http://blog.sina.com.cn/s/blog_8709e3120101czdr.html
今天更新系统，结果busybox起不来了，一顿折腾啊。运行图形界面的busybox，报出来的错误主要内容是下面让执行这句话：
'/etc/init.d/vboxdrv setup'
结果就是悲剧啊，我根本没找到这个文件，更没什么好执行的了。
命令行运行提示如下：
elta@elta:~$ virtualbox
WARNING: The character device /dev/vboxdrv does not exist.
Please install the virtualbox-ose-dkms package and the appropriate
headers, most likely linux-headers-generic.
You will not be able to start VMs until this problem is fixed.
提示安装
virtualbox-ose-dkms，后来证明这个包对我来说没有意义，不装也OK。第二句话说很可能是我头文件有问题。事实证明确实是这个样子。
elta@elta:~$ sudo dpkg-reconfigure virtualbox
virtualbox virtualbox-dkms virtualbox-ose-dkms virtualbox-qt
elta@elta:~$ sudo dpkg-reconfigure virtualbox
* Stopping VirtualBox kernel modules [ OK ]
* Starting VirtualBox kernel modules * No suitable module for running kernel found
[fail]
invoke-rc.d: initscript virtualbox, action "restart" failed.
错误提示没有找到相应的内核模块。
在这里我说一下我这边的错误原因，其实就是它提示的，没有找到相应的内核模块。
内核需要有：
linux-headers-版本号
linux-headers-版本号-generic
linux-image-版本号-generic
linux-image-extra-版本号-generic
这里几个文件的版本号要一致才行，之前我这边是版本号不一致，导致了无法找到相应的内核。用
sudo aptitude安装相应的模块，我装的是
3.5.0-20
。 警告：操作有风险，行动须谨慎！初学者切记切记

安装完内核之后，要重新config一下。
elta@elta:~$ sudo dpkg-reconfigure virtualbox-dkms

这里可以看到VirtualBox内核模块启动了，Virtualbox可以正常用了。
话说，要是看完了还不理解，可以在下面留言啊~
