I think you are hitting the issue described in
http://blog.xen.org/index.php/2012/04/30/memory-where-it-has-not-gone/

As it says towards the end you need to manually balloon up to the
target. This was fixed in Linux 3.5 according to the blog post and you
are using 3.2 from Wheezy.

IIRC the fix was too big/complex to be backportable.

Ian.
