FWIW: I rather see postcopy as a way of migrating guests forcibly and I know a service in which such a way is needed: emergency migration. There is also a product which does live migration when some hardware problems are detected (as a semi-FT solution) -- in such cases, we cannot wait until the guest becomes calm. Although I am not certain whether QEMU can be used for such products, it may be worth thinking about.
