Your demos show impressive speed in booting, machine resizing, and snapshotting. Kudos.
With that said, several hypervisors do support hot-resizing, snapshotting, and cross machine migration. Xen has excellent hot resize support, where VMWare has pushed hard for live migration and proper snapshotting over the years.
