cgroups help solve the same problem, for tasks. I suspect running properly isolated JVMs directly on host kernel would be faster than going through the hypervisor. I would love to see benchmarking numbers. But there are two problems on why people keep reinventing the wheel: - Current solution Isn't Sexy Enough, aka Not Invented Here. - Current corporate culture drives acquisitions of tech startups based on a) business, i.e. number of users, and b) innovative technology that doesn't exist anywhere else, reinforcing previous point. All this work to come up to yet another solution to the same old problems (IBM solved machine partitioning around 70s ?) is happening because engineers love to work on their specific pet projects and not solve other people's problems. Not that there's anything wrong with that.
