title: How to spread VUsers across multiple test agents when running load test
body: <p>I'm trying to run a load test in visual studio 2015. I have 1 test controller with 3 test agents setup. I have set the weighting of the agents to 33 each as I would like to spread the userload evenly across them. When I run the test I see evidence that it tries log in with the same user on all 3 agents, and as the tests are running I'm observing that there is 1 successfull login and 2 failed / user, which I assume is happening because they all try to log in at once.</p>
  
  <p>How can I make sure that 1 Vuser is assigned to one agent only? (1 agent can have multiple users of course)</p>
