Centos 5.2 with VirtualBox Guest Additions

Installing CentOS typically Requires > 4GB Hard Disk.
I suffered with the full hard disks when I started with 4.0GB HDD at the first time.

# yum install gcc kernel-headers kernel-devel autoconf automake

Press y if it asks something.

# cd /usr/src/kernels
# mv 2.6.18-92.1.22.el5-i686 2.6.18-92.el5-i686

Specific number can be differ; just remove the last two version number.

Insert the Guest Additions Disk from the menu "Devices"-"Install Guest Additions",

Move to mounted CDROM directory. Again, the specific version number can be differ.

# cd /media/VBOXADDITIONS_2.1.2_41185
# cp VBoxLinuxAdditions-x86.run ~
# cd ~
# ./VBoxLinuxAdditions-x86.run

It will install the additions. If successful, reboot.

# reboot

Now edit /etc/X11/xorg.conf file to enable various screen resolutions

Edit the SubSection "Display" in the Section "Screen",

SubSection "Display"

Viewport  0,0
Depth      24
Modes    "1920x1200" "1680x1050" "1440x900" "1280x800" "1024x768" "800x600" "640x480"

EndSubSection

You may add other screen additions as you like.

Then logout, and login.
