Vagrant Multi-Machine Parallel Start : <p>I'm trying to provision a master-master MySQL pair and they can only be configured correctly if both of them are up.</p>

<pre><code>Vagrant.configure("2") do |config|
  web.vm.box = "centos/7"

  config.vm.define "primary" do |primary|
    .......
  end

  config.vm.define "secondary" do |secondary|
    .......
  end
end
</code></pre>

<p>I've run thru this multiple times and Vagrant only starts the second vm after the first one is up.</p>

<p>Is there any way to force Vagrant to start up two VM's at the same time? </p>
