Step 1: Add Required Yum Repositories

Firstly we need to add VirtualBox yum repository in our system. To add VirtualBox repository add below content to /etc/yum.repos.d/virtualbox.repo .

# vim /etc/yum.repos.d/virtualbox.repo

[virtualbox]
name=Oracle Linux / RHEL / CentOS-$releasever / $basearch - VirtualBox
baseurl=http://download.virtualbox.org/virtualbox/rpm/el/$releasever/$basearch
enabled=1
gpgcheck=1
gpgkey=http://download.virtualbox.org/virtualbox/debian/oracle_vbox.asc

CentOS/RHEL Users also need to add EPEL yum repository using one of following command.

CentOS/RHEL 7, 64 Bit (x86_64): 
# rpm -Uvh http://ftp.jaist.ac.jp/pub/Linux/Fedora/epel/7/x86_64/e/epel-release-7-5.noarch.rpm

CentOS/RHEL 6, 32 Bit (i386): 
# rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm 

CentOS/RHEL 6, 64 Bit (x86_64): 
# rpm -Uvh http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm 

CentOS/RHEL 5, 32 Bit (i386): 
# rpm -Uvh http://dl.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm

# yum install gcc make patch  dkms qt libgomp 
# yum install kernel-headers kernel-devel fontforge binutils glibc-headers glibc-devel

Step 3: Setup Environment Variable

VirtualBox installation required kernel source code to install required modules, So we need to configure environment variable KERN_DIR to which VirtualBox get kernel source code. In my case latest kernel source is available in 2.6.32-504.3.3.el6.x86_64 directory under /usr/src/kernels/ . Make sure you are using correct source path.

# export KERN_DIR=/usr/src/kernels/2.6.32-504.3.3.el6.x86_64

# yum install VirtualBox-4.3

After installation we need to rebuild kernel modules using following command.

# service vboxdrv setup
