By default, tsung restrict itself to 800 users on a single VM (beam).
Moreover, if you add "use_controller_vm=true", it will restrict itself to a
single VM


So you can either (or simultaneously)
- increase maxusers for each <client> (warn: each 'user' consume a file
descriptor, so if you raise this limit over 1024, you may have to tune your
OS, see 'ulimit -n')
- remove the  'use_controller_vm' option. In this case, tsung will start a
new VM as soon as maxusers is reached.

I have already started several thousands users on a single machine.
