I believe that's correct. There used to be some issues with how much memory a single process could mmap, but I think that has been fixed in the later versions of QEMU. But, yes, you can't mmap more memory that you have on the machine.
With later versions of marss, we've been running 16G simulations just fine. Just out of curiosity, how does it fail? Do you get an error message when starting QEMU?
