如何用Vagrant配置win7¢os盒？

Question

如何使用Vagrant配置win7＆centos框。

我的Vagrantfile：

# -*- mode: ruby -*-
# vi: set ft=ruby :
VAGRANTFILE_API_VERSION = "2"
Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
   config.vm.box = "opensky/windows-7-professional-sp1-x64"
   config.vm.box_version = "0.1.0"
  config.vm.define :win7 do |win7|
   config.vm.provider "virtualbox" do |v|
    v.memory = 4096
   end
      win7.vm.network :private_network, ip: "192.168.22.167"
      win7.vm.network "forwarded_port", guest: 3389, host: 33890
  end
  config.vm.define :linux do |linux|
   config.vm.provider "virtualbox" do |v|
    v.memory = 2048
   end  
      linux.vm.box = "bento/centos-7.5"
      linux.vm.network "private_network", ip: "192.168.22.166"
      linux.vm.network :forwarded_port, host: 2201, guest: 22
      linux.vm.memory = "4096"
  end
end
