Once the game has loaded quckly pick your gun, If the timer is about 10 seconds press select and if your the one with full green bars or the only one connected then your the host
In the old Modern Warfare/ Cod4 before the game started in the lobby everyone names would dissapear quickly but you could still see the ranks; that's how you knew you were the host on that.
1) Choose you gun quickly, press select and find the only person with 4 bars.
2) Leave and you will migrate :p
3) Lag and see if just yours, or everyone elses connections goes down
