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 userswget http://download.virtualbox.org/virtualbox/rpm/fedora/virtualbox.repo## CentOS 7.3/6.9 and Red Hat (RHEL) 7.3/6.9 userswget 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

Check that that you are running latest installed kernel version
Output of following commands version numbers should match:

Bash

rpm -qa kernel |sort -V |tail -n 1uname -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 5.1.26)

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

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

Troubleshooting

If you have problems with KERN_DIR parameter or your kernel directory is not automatically detected then set KERN_DIR environment variable manually, using following method:

Bash

## 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_D
