Oh, interesting.

I have a tentative fix for this in rebase/master.

I've found that's fairly erratic even on native.  But I guess its likely
to be something to do with ACPI.  Though I would have thought that Xen
would have the responsibility for poweroff when the dom0 kernel
terminates itself.

I think you should continue using rebase/master rather than xen-tip/.
