VirtualBox Ruby Gem

The VirtualBox ruby gem is a library which allows anyone to control VirtualBox from ruby code! Create, destroy, start, stop, suspend, and resume virtual machines. Also list virtual machines, list hard drives, network devices, etc.

Installation and Requirements

First you need to install VirtualBox which is available for Windows, Linux, and OS X. After installation, install the gem:

sudo gem install virtualbox

The gem assumes that VBoxManage will be available on the PATH. If not, before using the gem, you must set the path to your VBoxManage binary:

VirtualBox::Command.vboxmanage = "/path/to/my/VBoxManage"

Basic Usage

The virtualbox gem is modeled after ActiveRecord. If you've used ActiveRecord, you'll feel very comfortable using the virtualbox gem.

There is a quick getting started guide to get you acquainted with the conventions of the virtualbox gem.

Complete documentation can be found at

Below are some examples:

require 'virtualbox'

vm = VirtualBox::VM.find("my-vm")

# Let's first print out some basic info about the VM
puts "Memory: #{vm.memory}"

vm.storage_controllers.each do |sc|
  sc.attached_devices.each do |device|
    puts "Attached Device: #{device.uuid}"

# Let's modify the memory and name...
vm.memory = 360 = "my-renamed-vm"

# Save it!

Or here is an example of creating a hard drive:

require 'virtualbox'

hd =
hd.location = "foo.vdi"
hd.size = 2000 # megabytes

Known Issues or Uncompleted Features

VirtualBox has a ton of features! As such, this gem is still not totally complete. You can see the features that are still left to do in the TODO file.

Reporting Bugs or Feature Requests

Please use the issue tracker.


If you'd like to contribute to VirtualBox, the first step to developing is to clone this repo, get bundler if you don't have it already, and do the following:

bundle install
bundle lock

This will run the test suite, which should come back all green! Then you're good to go!
