You can use the balloon driver - xm mem-set (or something like that)

It allows you to grow / shrink domains on request. If you want to grow 
beyond the initial allocation, I think you still need to pass an extra 
argument to the guest kernel at boot time telling it how large it might 
grow (otherwise it doesn't make its memory management structures big 
enough), but that's it.
