On this subject, we've had a lot of luck doing a potentially-paravirtualized GENERIC on powerpc, where you can boot the same GENERIC kernel on real hardware, on IBM's POWER hypervisor (in a project branch) and under Sony's Cell hypervisor on the PS3. Perhaps some of the infrastructure for that can be reused on x86. -Nathan
