What Hacker News says
5 sourcesYou can extract the drivers from the NetBSD kernel into exactly that, its called rump kernel http://www.rumpkernel.org and it can run on Xen among other places see https://github.com/rumpkernel/rumpuser-xen or just in userspace under Linux say - it is getting easier to run any application on it, there is still a bit more work needed (thread support is not there yet). Working on it though, and it should get easier to build and run application code over the next few months.
One advantage of using a BSD rather than Linux is licensing, as linking Linux kernel code into your application will probably force you to release as GPL. NetBSD also has an initial portability advantage, as you could always cross compile it.
In MirageOS: A Unikernel For The Xen HypervisorBased on "Why ZeroVM?" (http://zerovm.org/wiki/Why_ZeroVM), a large part of the motivation for ZeroVM is based on the premise that regular VMs require a full OS and are therefore unacceptably fat. However, there are multiple platforms for running unmodified applications directly on VMs without requiring a traditional OS, e.g. the work I've been involved with: https://github.com/anttikantee/rumpuser-xen/
Determinism, OTOH, sounds interesting at least on paper. Is there any experience from tests with real applications in real world scenarios?
In ZeroVM: Smaller, Lighter, FasterVery similar to: https://github.com/anttikantee/rumpuser-xen
In Rethinking the guest operating systemIt's already been done with a general purpose OS, see https://github.com/anttikantee/rumpuser-xen/
I agree, it was easy to do.
