This guide shows howto install VirtualBox 5.1 (currently 5.1.26) on Fedora 26/25/24/23/22, CentOS 7.3/6.9, Red Hat (RHEL) 7.3/6.9/5.11. This guide uses Virtual Box own yum repositories.

Note: Fedora 21/20/19/18 users can install VirtualBox 5.0, Fedora 17 users can install VirtualBox 4.3 and Fedora 16 users can install VirtualBox 4.2.

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 7.3/6.9 and Red Hat (RHEL) 7.3/6.9 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

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 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 5.1.26) 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
