Probably some structure not set up correctly -- my guess might be the
phys-to-machine mapping info that is supposed to get poked into the
shared_info page by the unprivileged guest. It is a list of the page
frames that make up the guest's p2m table. If you haven't init'ed it
then the xm_save tool will probably try to map NULL and hence the
error (Xen has low 1MB of memory marked as being an I/O page).

There should be a safety catch on this. DOM0 is definitely not
saveable!
