First of all we need to switch to root. We then add the virtualbox repo, with the below commands.
sudo dnf config-manager --add-repo=https://download.virtualbox.org/virtualbox/rpm/el/virtualbox.repo
yum install VirtualBox-6.0
For the exercises i have been following as part of RHEL 8 certification, by https://github.com/rdbreak/rhcsa8env i will also be installing the virtualbox extension pack, which is a requirement of these exercises
sudo VBoxManage extpack install Oracle_VM_VirtualBox_Extension_Pack-6.0.14.vbox-extpack
Virtualbox is now installed, you can start virtualbox by typing “virtualbox” or via the GUI
For the purpose of the exercise i am going to install the relevant dependencies for the lab.
vagrant plugin install vagrant-guest_ansible ; sudo dnf install -y git binutils gcc make patch libgomp glibc-headers glibc-devel kernel-headers kernel-devel dkms libvirt libvirt-devel ruby-devel libxslt-devel libxml2-devel
Before VirtualBox would start i had to install the below depencies.
yum install elfutils-libelf-devel yum install kernel-devel kernel-devel-4.18.0-80.11.2.el8_0.x86_6
I then needed to configure the virtualbox vagrant kernel driver.
sudo /sbin/rcvboxdrv setup
*NOTE* Virtualbox 6.0 is not supported by Vagrant if you install you will see the below error *
As part of the RHEL RHCE certification. I will be working through some labs created by the awesome rdbreak the labs can be found at.
When i initially installed the latest version of Virtualbox for the Labs i had an error code below when running.
vagrant up --provider=virtualbox
The error was
dean@dean:~/Downloads/rhcsa8env$ vagrant up --provider=virtualbox The provider 'virtualbox' that was requested to back the machine 'system' is reporting that it isn't usable on this system. The reason is shown below: Vagrant has detected that you have a version of VirtualBox installed that is not supported by this version of Vagrant. Please install one of the supported versions listed below to use Vagrant: 4.0, 4.1, 4.2, 4.3, 5.0, 5.1, 5.2 A Vagrant update may also be available that adds support for the version you specified. Please check www.vagrantup.com/downloads.html to download
To get around this i removed Virtual Box 6.0 and installed 5.2 with the below commands. A newer version of Vagrant for my OS was not available.
dean@dean:~/Downloads/rhcsa8env$ sudo apt remove VirtualBox-6.0 Reading package lists... Done
dean@dean:~/Downloads/rhcsa8env$ sudo apt install VirtualBox-5.2 Reading package lists... Done Building dependency tree
The labs are built using virtualbox and created using a Vagrant file, an ansible playbook is also used to build the lab environment.
If we have a look inside the vagrant file we can view what will be built along with the ip addressing scheme for the lab.
VAGRANTFILE_API_VERSION = "2" VAGRANT_DISABLE_VBOXSYMLINKCREATE = "1" file_to_disk1 = './disk-0-1.vdi' Vagrant.configure(VAGRANTFILE_API_VERSION) do |config| # Use same SSH key for each machine config.ssh.insert_key = false config.vm.box_check_update = false config.vm.define "system" do |system| system.vm.box = "rdbreak/rhel8node" # system.vm.hostname = "system.eight.example.com" system.vm.network "private_network", ip: "192.168.55.151" system.vm.network "private_network", ip: "192.168.55.175" system.vm.network "private_network", ip: "192.168.55.176" system.vm.synced_folder ".", "/vagrant", type: "rsync", rsync__exclude: ".git/" system.vm.provider "virtualbox" do |system| system.memory = "1024" if not File.exist?(file_to_disk1) system.customize ['createhd', '--filename', file_to_disk1, '--variant', 'Fixed', '--si$ end system.customize ['storagectl', :id, '--name', 'SATA Controller', '--add', 'sata', '--po$ system.customize ['storageattach', :id, '--storagectl', 'SATA Controller', '--port', 1,$ end
This will build three virtual machines they can be accessed via SSH which is my preferred method, as i will be accessing the labs from a different machine. The labs build the below machines
repo.eight.example.com ipa.eight.example.com system1.eight.example.com

I am now ready to take the exercises and work towards my RHCE Certification.
