I admit that I don't have any answers, especially since this whole thing is new to me. Like I said, I don't know much about KVM internals, so I just don't understand why KVM guests need to have access to these kernel header files as if they're user header files. The guests are still Linux kernels (or other OSes that think they're running as privileged code). -- Timur Tabi Linux kernel developer at Freescale
