Menginstall VBox Guest Additions on CentOS

At the beginning, I was confused to install the VirtualBox Guest Addition on my CentOS 5.6. But now, I can install the VBox Guest Additions and CentOS 5.6 run smoothly on my Windows 7 host. Hmm…please read my guide below to install the VBox Guest Additions non CentOS 5.6. This tutorial require an active internet connection on your system. Because you still need to download and install some packages from the internet. I am using VirtualBox version 4.0.8 on Windows 7 64 bit edition.

How to install VBox Guest Additions :

1. Change to root

su

2. Mount VirtualBox Guest Additions

Click Devices | Install Guest Additions…from your VirtualBox. See screenshot below:

3. Mount VirtualBox Guest Additions:

mkdir /media/VBoxGuestAdditions

mount -r /dev/cdrom /media/VBoxGuestAdditions

4. Now Install the packages below

yum install gcc kernel-devel kernel-headers

5. Add KERN_DIR environment variable

KERN_DIR=/usr/src/kernels/`uname -r`-`uname -m`

export KERN_DIR

6. Install Guest Additions

cd /media/VBoxGuestAdditions

sh ./VBoxLinuxAdditions.run

7. Up to this point, in some computer the VirtualBox Guest Additions may installed correctly. But if you got this message below, you may proceed to the next tutorial.

The headers for the current running kernel were not found. If the following
module compilation fails then this could be the reason.
The missing package can be probably installed with
yum install kernel-devel-2.6.18-238.el5
[FAILED]
Your system does not seem to be set up to build kernel modules.
Look at /var/log/vboxadd-install.log to find out what went wrong.
Once you have corrected it, you can run

/etc/init.d/vboxadd setup

to build them.

8. Still on Terminal, paste the command below

yum install kernel-devel-2.6.18-238.el5

9. Then start the step on point 6. And I got this message instead:

[root@localhost VBOXADDITIONS_4.0.8_71778]# sh ./VBoxLinuxAdditions.runVerifying archive integrity… All good.
