This document provides instructions for using Vagrant with VirtualBox to install and configure a virtual machine image. It describes how to install prerequisites, add a VM image, start and connect to the VM, provision it by running configuration scripts, configure resources like CPU, RAM and networking, copy files to the VM, enable the GUI, and includes references for further configuration.

1. Vagrant
Virtualbox provider guide

2. Install
Prerequisites
apt-get -y install virtualbox virtualbox-dkms vagrant
VM image
vagrant box add trusty64 https://oss-
binaries.phusionpassenger.com/vagrant/boxes/latest/ubuntu-14.04-amd64-
vbox.box

3. Operate
Start image
vagrant init && vagrant up
Connect
vagrant ssh
Suspend or shutdown
vagrant suspend && vagrant halt

4. Provisioning
Create bootstrap.sh with all the configuration
Modify Vagrantfile
config.vm.provision :shell, path: "bootstrap.sh"
Provision
vagrant provision

5. Bootstrap as a regular user
By default script is run as root, to run as a different user do the following.
case $(id -u) in
0) # doing root tasks
sudo -u vagrant -i $0
;;
*) # doing user tasks
;;
esac

6. Configure CPU and RAM
Modify Vagrantfile
config.vm.provider "virtualbox" do |vb|
vb.customize ["modifyvm", :id, "--memory", "1024"]
vb.customize ["modifyvm", :id, "--cpuexecutioncap", "50"]
vb.customize ["modifyvm", :id, "--ioapic", "on"]
vb.customize ["modifyvm", :id, "--cpus", "4"]
end

7. Configure network
Modify Vagrantfile
config.vm.network "public_network", bridge: "br-1", ip: "192.168.56.2"
config.vm.network "public_network", bridge: "br-2", ip: "192.168.57.2"
config.vm.network "public_network", bridge: "br-3", ip: "192.168.58.2"

8. Copy files to VM
Vagrant.configure("2") do |config|
# ... other configuration
config.vm.provision "file", source: "~/.gitconfig", destination: ".gitconfig"
end

9. GUI
config.vm.provider "virtualbox" do |vb|
vb.gui = true
end
