Within the standard Vagrant project configuration file, we can tell Vagrant that we wish to assign a name to a virtual machine being managed by the project. Within this subconfiguration, we provide the information Vagrant needs that is specific to that VM.

The syntax for the subconfigurations is as follows:

    #configuration specific to the virtual machine
end

This is applied to a project that requires two virtual machines, named server1 and server2, both running the precise64 box:

VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|

  config.vm.define :server1 do |server1|
