But those are going to be specific to the HV, the paravirt_ops allows the kernel to smoothly deal with having different HV's. So in a way it's an API interface to allow the kernel to deal with multiple different ABIs that exist today and will in the future. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
