Unless there is an known *architectural* limit in Xen on the lower bound of the memory for a guest DomU, then I agree - xend shouldn't impose an arbitrary one simply to act as 'hard hint' to prevent stupid users from doing stupid things (give 'em all the rope they want I say! :-) Care-and-feeding of naive users is best left to tools higher up the mgmt stack (IMO).

I agree with this. I'm also not sure about putting a lower bound in the balloon driver, but at least there we know that shrinking to <2% of original allocation is a very bad idea with very high probability.
