I really disliked all the stupid hacks we had both mine and Kent's solution. So I wrote a proper modern devops environment for Linux kernel development which is agnostic to from an architectural pespective to your OS, and virtualization environment, whether that be local or cloud. Addressing cloud and local virtual environment proved more diffcult and took a bit of time. But with a bit of patience, I found something suitable, and better than just hacks put together. It relies on ansible, vagrant and terraform. The later two unfortunately rely on Ruby... Let me be clear though, I have my own reservations about relying on solutions which rely on Ruby... but I find that startups *should* do a better job than a few kernel developers writing shell hacks for their own prefferred virtual environment. With a bit of proper ... nudging... I think we can steer things in the right direction. vagrant / terraform are at least perhaps more usable and popular then a few shell hacks. oscheck now embraces this solution, and you don't need to know much about setting up qemu, and even supports running on OS X. I've announced the effort through lkml as it turns out the nuts and bolts about the generic setup is actually a more common goal than for filesystems.
