I have another question about memory sharing among domains(domUs). I know that
grant table can be used for memory sharing. But my question is if it is possible
to setup memory sharing before domain starts. For example, suppose
I have 2 domUs: A and B. Before A and B are booted, is it possible to map
certain physical pages of A and B into the same machine pages? Any comment?

(btw, an unrelated question, if I do printk in Xen HVM, what's an easy
way to read that message?)
