Here's a little thing I've been hacking on. I was pretty amazed I could even get it working, let alone being so small and not too horrible to look at. A few people thought it would be useful for prototyping and hacking and running kvm tests, etc. So, thoughts on the overall idea and code structure?
There's possibly a few layering violations there with me short-cutting and not calling vhc method for checking cpu in nested at least, and a bit of cleanup and few loose ends, but hopefully nothing fundamentally terrible. It works and boots an L2 into a distro with unmodified Linux kernels running in the L1 and L2.
