Hint: Do NOT use "free". Use "xm list".
If you want, you can also run "xm mem-set 0 ..." later to assign the
unused memory back to dom0.

Note that Xen is different from Vmware/virtualbox w.r.t. memory
management. In Xen, you're actually recommended to set dom0's memory
as small as it'll ever be from the start. See
