I cant install virtualbox on my fedora..?

When you update your kernel you have to recompile VirtualBox’s kernel module to make it work again.

Let’s see how to recompile VirtualBox’s kernel module…

Requisites

First of all, you have to make sure you have installed the compilation tools (gcc and other stuff). If you haven’t (or you aren’t sure) just install the build-essential package:

yum install build-essential

You will also need your current kernel headers. In order to know what kernel you’re running type this:

uname -r

In my case, my PC is running kernel 2.6.29-4-686. Now install let’s the headers

yum install linux-headers-2.6.29-4-686

If you want it more generic, you can combine commands:

yum install linux-headers-$(uname -r)

This way will work no matter what kernel version you are running

Recompiling VirtualBox’s kernel module

 

Now it’s time to recompile the module. Just type this:

/etc/init.d/vboxdrv setup

Some Fedora FAQ (Frequently Asking Questions)

Q:I Cant Play *.Mp3 Files,*.MPG,*.Avi files on my fedora OS ?


Ans: Hi Friends, Fresh Fedora OS,cant play anything of the above,You want 2 install some additional packages in order to play the above files.

For that you want to download 2 additional rpms from rpmfusion.org

link: http://rpmfusion.org/Configuration

the rpms are

1)rpmfusion-free-release-stable.noarch.rpm
2)rpmfusion-non-free-release-stable.noarch.rpm

(rpm installation is quite simple,double click on the rpm file,enter root password to authenticate

otherwise take terminal from applications-->system tools-->terminal,

type su
then enter root password,
after dat type

rpm -ivh /home/username/Downloads/rpmfusion-free-release-stable.noarch.rpm
rpm -ivh /home/username/Downloads/rpmfusion-non-free-release-stable.noarch.rpm

)


after that try to play one mp3 file,then our system automatically checking for plug-ins from the repository which added above, same as in the case of
*.avi,*.mpg files
