vagrant-vbguest

vagrant-vbguest is a Vagrant plugin which automatically installs the host's VirtualBox Guest Additions on the guest system.

Installation

Requires vagrant 0.9.4 or later (including 1.x)

Vagrant ≥ 1.1

$ vagrant plugin install vagrant-vbguest

Vagrant 1.0 and older

Since vagrant v1.0.0 the preferred installation method for vagrant is using the provided packages or installers. If you installed vagrant that way, you need to use vagrant's gem wrapper:

$ vagrant gem install vagrant-vbguest

If you installed vagrant using RubyGems, use:

$ gem install vagrant-vbguest

Compatibly for vagrant 0.8 is provided by version 0.0.3 (which lacks a bunch of new options)

Configuration / Usage

If you're lucky, vagrant-vbguest does not require any configuration. However, here is an example of Vagrantfile:

Vagrant::Config.run do |config|
  # we will try to autodetect this path. 
  # However, if we cannot or you have a special one you may pass it like:
  # config.vbguest.iso_path = "#{ENV['HOME']}/Downloads/VBoxGuestAdditions.iso"
  # or
  # config.vbguest.iso_path = "http://company.server/VirtualBox/%{version}/VBoxGuestAdditions.iso"
  
  # set auto_update to false, if you do NOT want to check the correct 
  # additions version when booting this machine
  config.vbguest.auto_update = false
  
  # do NOT download the iso file from a webserver
  config.vbguest.no_remote = true
end

Config options

iso_path : The full path or URL to the VBoxGuestAdditions.iso file.
The iso_path may contain the optional placeholder %{version} replaced with detected VirtualBox version (e.g. 4.1.8). The default URI for the actual iso download is: http://download.virtualbox.org/virtualbox/%{version}/VBoxGuestAdditions_%{version}.iso
vbguest will try to autodetect the best option for your system. WTF? see below.
auto_update (Boolean, default: true) : Whether to check the correct additions version on each start (where start is not resuming a box).
auto_reboot (Boolean, default: true when running as a middleware, false when running as a command) : Whether to reboot the box after GuestAdditions has been installed, but not loaded.
no_install (Boolean, default: false) : Whether to check the correct additions version only. This will warn you about version mis-matches, but will not try to install anything.
no_remote (Boolean, default: false) : Whether to not download the iso file from a remote location. This includes any http location!
installer (VagrantVbguest::Installers::Base, optional) : Reference to a (custom) installer class
installer_arguments (Array, default: []) : List of additional arguments to pass to the installer. eg: %w{--nox11 --force} would execute VBoxLinuxAdditions.run install --nox11 --force

Global Configuration

Using Vagrantfile Load Order you may change default configuration values. Edit (create, if missing) your ~/.vagrant.d/Vagrantfile like this:

For Vagrant >= 1.1.0 use:

Vagrant.configure("2") do |config|
  config.vbguest.auto_update = false
end

For older versions of Vagrant:

# vagrant's autoloading may not have kicked in
require 'vagrant-vbguest' unless defined? VagrantVbguest::Config
VagrantVbguest::Config.auto_update = false

Settings in a project's Vagrantfile will overwrite those setting. When executed as a command, command line arguments will overwrite all of the above.

Running as a middleware

Running as a middleware is the default way of using vagrant-vbguest. It will run automatically right after the box started. This is each time the box boots, i.e. vagrant up or vagrant reload. It won't run on vagrant resume (or vagrant up a suspended box) to save you some time resuming a box.

You may switch off the middleware by setting the vm's config vbguest.auto_update to false. This is a per box setting. On multi vm environments you need to set that for each vm.

When vagrant-vbguest is running it will provide you some logs:

[...]

[default] Booting VM...
[default] Waiting for VM to boot. This can take a few minutes.

The plugin's part starts at [default] Installing Virtualbox Guest Additions 4.1.14 - guest's version is 4.1.1, telling you that:

the guest addition of the box default is outdated (or mismatching)
which guest additions iso file will be used
which installer script will be used
all the VirtualBox Guest Additions installer output.

No worries on the Installing the Window System drivers ...fail!. Most dev boxes you are using won't run a Window Server, thus it's absolutely safe to ignore that error.

When everything is fine, and no update is needed, you see log like:

...
[default] Booting VM...
[default] Waiting for VM to boot. This can take a few minutes.
[default] VM booted and ready for use!
[default] GuestAdditions 4.2.6 running --- OK.
...

Running as a Command

When you switched off the middleware auto update, or you have a box up and running you may also run the installer manually.

$ vagrant vbguest [vm-name] [--do start|rebuild|install] [--status] [-f|--force] [-b|--auto-reboot] [-R|--no-remote] [--iso VBoxGuestAdditions.iso]

For example, when you just updated VirtualBox on your host system, you should update the guest additions right away. However, you may need to reload the box to get the guest additions working.

If you want to check the guest additions version, without installing, you may run:

$ vagrant vbguest --status

Telling you either about a version mismatch:

[default] GuestAdditions versions on your host (4.2.6) and guest (4.1.0) do not match.

or a match:

[default] GuestAdditions 4.2.6 running --- OK.

The auto-reboot is turned off by default when running as a command. Vbguest will suggest you to reboot the box when needed. To turn it on simply pass the --auto-reboot parameter:

$ vagrant vbguest --auto-reboot

You can also pass vagrant's reload options like:

$ vagrant vbguest --auto-reboot --no-provision

ISO autodetection

vagrant-vbguest will try to autodetect a VirtualBox GuestAdditions iso file on your system, which usually matches your installed version of VirtualBox. If it cannot find one, it downloads one from the web (virtualbox.org).
Those places will be checked in order:

Checks your VirtualBox "Virtual Media Maganger" for a DVD called "VBoxGuestAdditions.iso"
Guess by your host operating system:

for linux : /usr/share/virtualbox/VBoxGuestAdditions.iso
for Mac : /Applications/VirtualBox.app/Contents/MacOS/VBoxGuestAdditions.iso
for Windows : %PROGRAMFILES%/Oracle/VirtualBox/VBoxGuestAdditions.iso

Automatic reboot

The VirtualBox GuestAdditions Installer will try to load the newly built kernel module. However the installer may fail to load, just as it is happening when updating GuestAdditions from version 4.1 to 4.2.

Hence, vbguest will check for a loaded kernel module after the installation has finished and reboots the box, if it could not find one.

Advanced Usage

vagrant-vbguest provides installers for generic linux and debian/ubuntu.
Installers take care of the whole installation process, that includes where to save the iso file inside the guest and where to mount it.

class MyInstaller < VagrantVbguest::Installers::Linux

  # use /temp instead of /tmp
  def tmp_path
    '/temp/VBoxGuestAdditions.iso'
  end

  # use /media instead of /mnt
  def mount_point
    '/media'
  end

  def install(opts=nil, &block)
    communicate.sudo('my_distos_way_of_preparing_guestadditions_installation', opts, &block)
    # calling `super` will run the installation
    # also it takes care of uploading the right iso file into the box
    # and cleaning up afterward
    super
  end
end

Vagrant::Config.run do |config|
  config.vbguest.installer = MyInstaller
end

Known Issues

The installer script, which mounts and runs the GuestAdditions Installer Binary, works on Linux only. Most likely it will run on most Unix-like platforms.
The installer script requires a directory /mnt on the guest system
On multi vm boxes, the iso file will be downloaded for each vm
The plugin installation on Windows host systems may not work as expected (using vagrant gem install vagrant-vbguest). Try C:\vagrant\vagrant\embedded\bin\gem.bat install vagrant-vbguest instead. (See issue #19)
