Perhaps you need to enable xenfs in your kernel build and mount it
on /proc/xen in order to gain access to /proc/xen/xsd*?

pvops only supports balloon via a sysfs interface not proc. There is a
patch in xen-unstable.hg from Jeremy Fitzhardinge which fixes this but
you'll either need to use xen-unstable or backport it to whatever you
are using (it's pretty simple, IIRC).
