Hi, this is my first post on this blog. Here I want to share about How to install VirtualBox Guest Additions on CentOS 6.4 Linux. After installing CentOS on VirtualBox, the first thing to do is to install the Guest Additions. The VirtualBox Guest Additions will improve the virtual machine guest performance and we can get full screen or seamless display for the guest. See how to install VirtualBox Guest Additions on CentOS 6.4 below.
First, boot your CentOS and open Terminal. Login as root and type the following command to update the kernel first.
yum update kernel*
Next, reboot upon completion.
Next is to install several things. Execute this command:
yum install kernel-headers kernel-devel gcc
When finished, you can start installing the Guest Additions. Go to Devices | Install Guest Additions from the VirtualBox menu. Now on your guest machine you should see the GuestAdditions mounted on your Desktop.
Double click the VOXADDITIONS icon and then press Open Autorun Prompt. Provide your root password and CentOS will install and finish the rest. Reboot when finished and now your VirtualBox Guest Additions should be enabled after reboot.
