So all the current docs say that everything except static-max is
unused, however this is not my experience as I mentioned, in that when
running a cooperative kernel with a ballooning driver you actually
will change the amount of memory the guest says is available (via top,
etc). Can someone comment on the changes that have been made in XCP
with the static min and dynamic min/max now being used?

Thanks,
David
