Ah.
I think that the paravirt drivers for HVM guests that are shipped in the 3.1
source tree do allow you to use mem-set with HVM guests. So you should be
able to make this sort-of work if you install those...
I'd think you'll only be able to shrink an HVM guest relative to its original
allocation. I could be wrong though, maybe the mem= trick Denny mentioned
for PV guests would work on HVM as well.
In any case, you could work around this by creating HVM guests with the
largest memory you ever want them to have, then shrinking them down to
something more reasonable.
Cheers,
Mark
