Vagrant is a tool for managing and configuring virtualised development environments.
Vagrant has a concept of 'providers', which map to the virtualisation engine and its API. The most popular and well-supported provider is Virtualbox; plugins exist for
vmware and more.
Vagrant uses a mostly declarative
Vagrantfile to define virtualised machines. A single Vagrantfile can define multiple machines.

Install the package.
Vagrant has a middleware architecture providing support for powerful plugins.
Plugins can be installed with Vagrant's built-in plugin manager. You can specify multiple plugins to install:
$ vagrant plugin install vagrant-vbguest vagrant-share
To install the plugin, make sure
libvirtd.service has been started.
$ vagrant plugin install vagrant-libvirt
Once the plugin is installed the
libvirt provider will be available:
$ vagrant up --provider=libvirt
First installfrom the official repositories, then:
$ vagrant plugin install vagrant-lxc
Next, configure lxc as directed in the official repository. The plugin can now be used with a
Vagrantfile like so:
VAGRANTFILE_API_VERSION = "2" Vagrant.configure("2") do |config| config.vm.define "main" do |config| config.vm.box = 'http://bit.ly/vagrant-lxc-wheezy64-2013-10-23' config.vm.provider :lxc do |lxc| lxc.customize 'cgroup.memory.limit_in_bytes', '512M' end config.vm.provision :shell do |shell| shell.path = 'provision.sh' end end end
provision.sh file should be a shell script beside the
Vagrantfile. Do whatever setup is appropriate; for example, to remove puppet, which is packaged in the above box:
rm /etc/apt/sources.list.d/puppetlabs.list apt-get purge -y puppet facter hiera puppet-common puppetlabs-release ruby-rgen
Provisioners allow you to automatically install software, alter and automate configurations as part of the vagrant up process. The most common provisioner is.
Base Boxes for Vagrant
Here is a list of places to get all sorts of vagrant base boxes for different purposes: development, testing, or even production.
- The official Arch Linux vagrant boxes. The corresponding Arch-boxes project contains the packerfile and provisioning scripts used for building.
- A well maintained up-to-date Arch Linux x86_64 base box for Vagrant.
- Vagrant Cloud is HashiCorp's official site for Vagrant boxes. You can browse user-submitted boxes or upload your own. A single Vagrant Cloud box can support multiple providers with versioning.
- vagrantbox.es—A List of vagrant base boxes. Initiated by Gareth Rushgrove @garethr hosted on Heroku using Nginx. See the story here: The Vagrantbox.es Story.
- Bento is a project that encapsulates Packer templates for building Vagrant base boxes. A subset of templates are built and published to the bento org on Vagrant Cloud.
- Puppet Labs Vagrant Boxes—Pre-rolled vagrant boxes, ready for use. Made by the folks at Puppet Labs.
- Vagrant Ubuntu Cloud Images—It has been there since Jan, 2013. For some reason Canonical has NOT officially promoted it yet, may be still in beta. Remember these are vanilla images, NOT very useful without Chef or Puppet.
- packer-arch project on Github provides configuration files to build light Arch Linux Vagrant images from the official iso image, using .
No ping between host and vagrant box (host-only networking)
Sometimes there are troubles with host-only networking not functioning. Host have no ip on vboxnet interface, host cannot ping vagrant boxes and cannot be pinged from them. This is solved by installing good old this thread by kevin1024as mentioned in
Virtual machine is not network accessible from the Arch host OS
As of version 1.8.4, Vagrant appears to use the deprecated
route command to configure routing to the virtual network interface which bridges to the virtual machine(s). If
route is not installed, you will not be able to access the virtual machine from the host OS due to the lack of suitable route. The solution, as mentioned above, is to install the package, which includes the route command.
Installingpackage may solve this problem.
Install the package. Enable (v3 and) UDP support by editing
/etc/nfs.conf and uncommenting the following lines:
[nfsd] vers3=y udp=y
nfs-server.service to apply the changes immediately.
Error starting network 'default': internal error: Failed to initialize a valid firewall backend
Unable to ssh to vagrant guest
Check that virtualization is enabled in your BIOS. Because vagrant reports that the vm guest is booted, you would think that all was well with virtualization, but some vagrant boxes (e.g. tantegerda1/archlinux) allow you to get all the way to the ssh stage before the lack of cpu virtualization capabilities bites you.
Could not get preferred machine for domain
Error while creating domain: Error saving the server: Call to virDomainDefineXML failed: could not get preferred machine for domain
