Do you REALLY need to suspend the application, instead of shutting it down?

It will be impossible. Moving the machine state requires identical
condition on both source and target. For example, when moving between
two Xen dom0s, the CPUs need to be the same (or at least same-enough),
that even live migrate between AMD <-> intel doesn't always work.

You want to live-migrate between a full-virtualization/PV setup (that
can run full-blown OS, with their own kernel) to something that only
supports binary translation for running a single application. It's
simply can't work.
