Install Procedure for VirtualBox 6.0

Requirements

To install VirtualBox you will need the following:
  • a installed and supported operating system (e.g. CentOS 8.x)
  • root-access
  • a fast internet connection
  • EPEL
  • VirtualBox - Repo

Preliminary Note

This procedure is based on a documentation supplied by www.proclos.com.

You may also find additional information at

a possible solution to get the autostart-service up and running finally is found here:
http://nathangiesbrecht.com/centos-7-virtualbox-vboxautostart-service-setup

Install Virtual Box

Install DKMS

Install Dynamic Kernel Module System: (automatically installs appropriate kernel modules per
selected version)

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

Install VirtualBox

yum install VirtualBox-6.0

Rebuild kernel modules with following command:

/usr/lib/virtualbox/vboxdrv.sh setup

Setup vboxusers

The Linux installers create the system user group vboxusers during installation. Any system user who is going to use USB devices from VirtualBox guests must be a member of that group. A user can be made a member of the group vboxusers through the GUI user/group management or at the command line with

usermod -a -G vboxusers username

Note that adding an active user to that group will require that user to log out and back in again. This should be done manually after successful installation of the package.

Start virtual box.

GNOME-Menu->Applications->System Tools->Oracle VM VirtualBox

Install VirtualBox-Extension

Download the extension from the virtualbox homepage www.virtualbox.org.
Add the extension (VirtualBox 6.0.x Oracle VM VirtualBox Extension Pack) using Preferences->Extensions->Add. This extension is needed to attach usb devices to the guest machines and to be
able to connect to guest machines using WindowsRemote Desktop-Client, which is very handy, if you need graphical access.

VBextpack_update.sh

#!/bin/bash
version=$(vboxmanage -v)
echo $version
var1=$(echo $version | cut -d 'r' -f 1)
echo $var1
var2=$(echo $version | cut -d 'r' -f 2)
echo $var2
file="Oracle_VM_VirtualBox_Extension_Pack-$var1-$var2.vbox-extpack" 
echo $file
wget http://download.virtualbox.org/virtualbox/$var1/$file -O /tmp/$file
VBoxManage extpack uninstall "Oracle VM VirtualBox Extension Pack" 
VBoxManage extpack install /tmp/$file --replace

Automatic Start/Stop of virtual machines systemd-style

this is taken from http://www.ericerfanian.com/automatically-starting-virtualbox-vms-on-archlinux-using-systemd/

Add a file called vboxvmservice.service@ in /etc/systemd/system/.

[Unit]
Description=VBox Virtual Machine %i Service
Requires=systemd-modules-load.service
After=systemd-modules-load.service

[Service]
User=user
Group=vboxusers
ExecStart=/usr/bin/VBoxHeadless -s %i
ExecStop=/usr/bin/VBoxManage controlvm %i savestate

[Install]
WantedBy=multi-user.target

Replace the user after user= with the username you want to run the VMs. Make sure that the user is in the vboxusers group. If you need to delay the start of the VMs until after your network is started or a network share is mounted, locate the service you want to wait for using ‘systemctl’ and then substitute the service, mount, or network behind ‘After=’.

You can also replace ‘savestate’ in ‘ExecStop=’ with ‘poweroff’ or ‘acpipowerbutton’ to hard-stop the VM, or ask for a clean shut-down, respectively.

To enable one or more VMs at boot, enter:

systemctl enable vboxvmservice@vm_name.service

h2. 5 Automatic Start/Stop of virtual machines SystemV-style

As an alternative to the following solution, someone might find https://sourceforge.net/projects/vboxtool/ interesting to investigate.

To automatically run the guest machines in headless mode on host machine startup, do the following((A new feature of VirtualBox 4.2 is a supplied init-script to automatically start/stop virtual-machines. This I've not tested yet. The old 4.1 way is still working fine. So this section remains as 4.1 until something better is tested.
)):

add the list of names of the virtual machines that should be started / stopped automatically in following files:
/etc/virtualbox/machines_enabled_start and /etc/virtualbox/machines_enabled_stop

Each virtual machine name has to in a separate line. You can create and fill the files by the use of vim or any other text-editor.

cd /etc
mkdir virtualbox
vim /etc/virtualbox/machines_enabled_start

vim /etc/virtualbox/machines_enabled_stop

Afterwards you can check the file-content by

cat /etc/virtualbox/machines_enabled_start

the content should look like:
firewall-pfsense
clusterOne
clusterTwo
postgresql-solo
windows7-janus

As the machines are started and stopped in the same order as in the files being listed you maybe want to stop the machines in reverse order.
cat /etc/virtualbox/machines_enabled_stop

the content could look like:
windows7-janus
postgresql-solo
clusterTwo
clusterOne
firewall-pfsense

Also create a file /etc/init.d/vboxcontrol with following content:

Don't forget to set the correct user VM_USER

#! /bin/sh
# vboxcontrol   Startup script for VirtualBox Virtual Machines
#
# chkconfig: 345 98 02

To make the file executeable do

chmod +x /etc/init.d/vboxcontrol

Add vboxcontrol as service:
cd /etc/init.d
chkconfig --add vboxcontrol

Manually start the service
service vboxcontrol start

you can check the runlevels by
chkconfig --list vboxcontrol

you should get an output like:
vboxcontrol     0:off   1:off   2:off   3:on   4:on   5:on   6:off

With this setup, guest machines are also automatically shutdown cleanly in a host shutdown
process. The shell-script vboxcontrol processes the file machines_enabled_stop. The first machines is sent a ACPI-Poweroff-Signal, after 10 seconds the second machine and so on. After the last machine have got the ACPI-Poweroff-Signal the script waits until all machines have reached power-off-status. By doing so a crashed or hanging virtual machine will prevent a shutdown of the host-system.

At boot-time each virtual machine being listed in the file machines_enabled_start is being started according to the order within the file. The time gap between each machine is 20 seconds.

Problem

KVM and Virtualbox side by side

VirtualBox might not work while KVM extensions are active
