Virtualization and its live migration is becoming an innovation blocker. Recall that the original problem that we are trying to solve is "How does an application get access to resources on demand?" In other words, how do we get an operating system that scales to an entire datacenter. Even with virtualization my application is contrained to an operating system.
What we need is a language run-time like JVM that talks to a hypervisor directly. What we need is a hypervisor that abstracts resource for an application at a level that the application understands i.e. tables, databases, files, serversockets and clientsockets, IO etc.
JeOS (Just enough OS) is a slow-start in a wrong direction. What we need is JNOS (Just No OS!).
