1. Change to root User

Bash

su -
## OR ##
sudo -i

2. Install Fedora or RHEL Repo Files

Bash

cd /etc/yum.repos.d/

## Fedora 26/25/24/23/22/21/20/19/18/17/16 users
wget http://download.virtualbox.org/virtualbox/rpm/fedora/virtualbox.repo

## CentOS 7.4/6.9 and Red Hat (RHEL) 7.4/6.9 users
wget http://download.virtualbox.org/virtualbox/rpm/rhel/virtualbox.repo

3. Update latest packages and check your kernel version

Update packages

Bash

## Fedora 26/25/24/23/22 ##
dnf update

## Fedora 21/20/19/18/17/16 and CentOS/RHEL 7/6/5 ##
yum update


While executing yum update if you get any dependency errorfor glibc use the following to resolve it:

rpm -qa | grep glibc
You may see duplicates for either glibc or glibc common. There might be a common version in between any two packages of glibc and glibc-common. Remove the package which has uncommon version.

You can also check for duplicates with the following command:
yum list –showduplicates glibc

rpm -e glibc-common-2.17-196.el7

rpm -qa kernel |sort -V |tail -n 1

uname -r

Note: If you got kernel update or run older kernel than newest installed then reboot:

Bash

reboot

4. Install following dependency packages

CentOS 7/6/5 and Red Hat (RHEL) 7/6/5 needs EPEL repository, install it with following command:

Bash

## CentOS 7 and RHEL 7 ##
rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

## CentOS 6 and RHEL 6 ##
rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm

## CentOS 5 and RHEL 5 ##
rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-5.noarch.rpm
Bash

## Fedora 26/25/24/23/22 ##
dnf install binutils gcc make patch libgomp glibc-headers glibc-devel kernel-headers kernel-devel dkms

## Fedora 21/20/19/18/17/16 and CentOS/RHEL 7/6/5 ##
yum install binutils gcc make patch libgomp glibc-headers glibc-devel kernel-headers kernel-devel dkms

## PAE kernel users install ##
## Fedora 24/23/22 ##
dnf install binutils gcc make patch libgomp glibc-headers glibc-devel kernel-headers kernel-PAE-devel dkms

## Fedora 21/20/19/18/17/16 and CentOS/RHEL 7/6/5 ##
yum install binutils gcc make patch libgomp glibc-headers glibc-devel kernel-headers kernel-PAE-devel dkms

5. Install VirtualBox Latest Version 5.1 (currently 5.1.28)

Bash

## Fedora 26/25/24/23/22 ##
dnf install VirtualBox-5.1

## Fedora 21/20/19/18/17/16/15/14 and CentOS/RHEL 7/6/5 ##
yum install VirtualBox-5.1

Note:
This command create automatically vboxusers group and VirtualBox user must be member of that group.
This command also build needed kernel modules.
Package is VirtualBox-5.1 not VirtualBox.

Rebuild kernel modules with following command:

Bash

## Fedora 26/25/24/23/22/21/20/19 and CentOS/RHEL 7 ##
/usr/lib/virtualbox/vboxdrv.sh setup

## Fedora 18/17/16 and CentOS/RHEL 6/5 ##
/etc/init.d/vboxdrv setup
## OR ##
service vboxdrv setup

You might get the following error:

vboxdrv.sh: Stopping VirtualBox services.
vboxdrv.sh: Building VirtualBox kernel modules.
This system is not currently set up to build kernel modules (system extensions).
Running the following commands should set the system up correctly:

yum install kernel-devel-3.10.0-327.28.2.el7.x86_64
(The last command may fail if your system is not fully updated.)
yum install kernel-devel
vboxdrv.sh: failed: Look at /var/log/vbox-install.log to find out what went wrong.

Execute the following: yum install kernel-devel

If the error still persists look in the log: /var/log/vbox-install.log
If you find the following error: Error: unable to find the sources of your current Linux kernel. Specify KERN_DIR=<directory> and run Make again. Stop.

## Current running kernel on Fedora ##
KERN_DIR=/usr/src/kernels/`uname -r`
 
## Current running kernel on CentOS and Red Hat (RHEL) ##
KERN_DIR=/usr/src/kernels/`uname -r`-`uname -m`
 
## Fedora example ##
KERN_DIR=/usr/src/kernels/2.6.33.5-124.fc13.i686
 
## CentOS and Red Hat (RHEL) example ##
KERN_DIR=/usr/src/kernels/2.6.18-194.11.1.el5-x86_64
 
## Export KERN_DIR ##
export KERN_DIR

Make sure your system is rebooted.

6. Add VirtualBox User(s) to vboxusers Group

Replace user_name with your own user name or some another real user name.

Bash

usermod -a -G vboxusers user_name

7. Start VirtualBox

Use launcher from menu or simply run:

Bash

VirtualBox
