Should be unconditionally printed during Xen boot. Not when memory sharing
is first used.

I think you run the xenpaging daemon manually on each domain you want to
have paged to disc. The daemon is probably under /usr/sbin/xenpaging. It
takes two arguments: domain-id and memory allocated to the domain, in 4kB
pages (e.g., memory in MB, multiplied by 256).
