CentOS 7 VirtualBox Guest Additions Installation

CentOS 7 VirtualBox Guest Additions Installation Tutorial

In the following tutorial, I’ll demonstrate how to install Guest Additions on your VirtualBox hosted CentOS 7 Minimal machine.

Although this tutorial is intended for CentOS 7 minimal, it’s will probably also work on other CentOS releases.

Update your VirtualBox

VirtualBox 4.3.12 or later is required for support in CentOS 7.x, So if you’re using older version of VirtualBox – it’s time for you to upgrade.

Update and Reboot system

After successful installation of your new and shining CentOS box, CentOS-7-installation-VirtualBox

Important Before anything!, I’d advice you to update your CentOS & reboot:

yum update
reboot

After, also try to update your kernel and reboot:

yum update kernel
reboot

You will need to be the root user for the following routine or “su -”

Prerequisities

In order to compile the guest additions you have to install make, gcc, kernel-devel in order to Install VirtualBox Guest Additions installation script.

yum install gcc make kernel-devel

OR, I’ll recommend installing the entire “Developer tools” group which will help you to avoid a lot of trouble later:

yum groupinstall "Development tools"
yum install kernel-devel

Install VirtualBox Guest Additions

Mount your guest additions:

VirtuallBox-MountGuestAdditions

Type at command::

cd /mnt
mkdir cdrom && mount /dev/cdrom /mnt/cdrom
cd cdrom && ./VBoxLinuxAdditions.run

centos-7-guest-additions

If everything “OK” – You have Guest Additions properly installed on your Centos (Minimal) machine. now Reboot:

reboot

 

That’s it!
