I just installed CentOS 6.4 on my VirtualBox and now I need to install the VirtualBox Guest Additions on my CentOS 6.4. We need to install several packages in order to install the Guest Additions. without it, the installation will failed because of the mismatch of the Kernel version. So, before installing Guest Additions, I do the following on Terminal (as root)
yum install kernel-headers make gcc
yum update kernel*
reboot
After reboot, I go to Devices | Install Guest Additions and follow the wizard. When done, reboot is required and viola, my CentOS 6.4 is now equipped with VirtualBox Guest Additions so I can get a full screen and seamless mode enabled.
