it's limited by the physical resources that you have available, there should 
be no other hardcoded limit (or at least only a very high and more 
theoretical limit).

If you have assigned all of your memory to guests, then you will not be able 
to create another new guest. Same if you run out of harddisk. CPU shouldn't 
be a problem at all, even it doesn't make sense to have hundreds of guests 
running on just one physical cpu.

My "biggest" setup was a dual xeon server with 4gb ram and 24 domUs running 
(without any problems). If you have more ram available then even 50 domUs 
should be possible on such a server (if you have more or less just tiny 
domU's at least).
