title: how to start the test in parallel with selenium grid 2
body: <p>I am new at this.
  What I want to do is start the test cases on multiple browsers at the same time.
  This is the xml file that I use to run:</p>
  
  <pre><code>&lt;suite name="Selenium Grid with webdriver" verbose="3" parallel="tests" thread-count="2"&gt;
      &lt;test name ="Selenium Grid demo"&gt;
          &lt;parameter name ="browser" value = "iexplore"/&gt;
          &lt;classes&gt;
              &lt;class name="test.GridWithWebdriver"/&gt;
  
          &lt;/classes&gt;
      &lt;/test&gt;
  
      &lt;test name ="Selenium Grid demo2"&gt;
          &lt;parameter name ="browser" value = "firefox"/&gt;
          &lt;classes&gt;
              &lt;class name="test.GridWithWebdriver"/&gt;
          &lt;/classes&gt;
      &lt;/test&gt;
  
  &lt;/suite&gt;
  </code></pre>
  
  <p>The problem is the second test which runs on firefox only run after the one runs on IE finishes.
  I tried to run the hub with max instances = 5 by this command:</p>
  
  <pre><code>java -jar selenium-server-standalone-2.24.1.jar -role hub -maxInstances=5
  </code></pre>
  
  <p>But then I still see the warning max instance not specified, using default = 1
  So maybe this is why it's not running in parallel?
  Also if I want to start the same test case on 3 IE browsers how can I do it?
  Please help me with the setup.
  Thank you</p>
