Vagrantutil is a toolset for managing Vagrant boxes via an idiomatic Go (Golang) API. The package is work in progress, so please vendor it. Checkout the examples below for the usage.
go get github.com/koding/vagrantutilpackage main
import (
	"log"
	"github.com/koding/vagrantutil"
)
func main() {
	vagrant, _ := vagrantutil.NewVagrant("myfolder")
	vagrant.Create(`# -*- mode: ruby -*-
# vi: set ft=ruby :
VAGRANTFILE_API_VERSION = "2"
Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
  config.vm.box = "ubuntu/trusty64"
  config.vm.hostname = "vagrant"
  config.vm.provider "virtualbox" do |vb|
    # Use VBoxManage to customize the VM. For example to change memory:
    vb.customize ["modifyvm", :id, "--memory", "2048", "--cpus", "2"]
  end
end
`)
	status, _ := vagrant.Status() // prints "NotCreated"
	// starts the box
	output, _ := vagrant.Up()
	// print the output
	for line := range output {
		log.Println(line)
	}
	// stop/halt the box
	vagrant.Halt()
	// destroy the box
	vagrant.Destroy()
}
