Install Dependency Packages for VirtualBox

VirtualBox uses vboxdrv kernel module to control and allocate physical memory for execution of guest operating systems. Without this module, you can still use the VirtualBox to create and configure virtual machines, but they will not work. So, to make VirtualBox fully functional you will need to update your system first, then install some additional modules like DKMS, kernel-headers and kernel-devel and some dependency packages.

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

Install VirtualBox 4.3

Once you’ve installed all the needed dependency packages, you can install latest version ofVirtualBox using following command.

# yum install VirtualBox-4.3

Rebuild Kernel Modules for VirtualBox 4.3

The below command will automatically create vboxusers group and user and also search and automatically rebuild required kernel modules. If the below build process fails, you will get a warning messages. Please have a look at /var/log/vbox-install.log to trace why the build process failed.

# /etc/init.d/vboxdrv setup
OR 
# service vboxdrv setup

Troubleshooting

If you get any error message like KERN_DIR or if your kernel source directory not detected automatically by build process, you can set it by using following command. Make sure you change kernel version according to your system as shown in red color.

## RHEL / CentOS / Fedora ##
KERN_DIR=/usr/src/kernels/2.6.18-194.11.1.el5-x86_64

## Export KERN_DIR ##
export KERN_DIR
