It depends on functions like > qemu_ram_map() which are not present in qemu.git (and are present in > qemu-kvm.git). It is against qemu-kvm.git. Is qemu_ram_map() going into qemu.git? Another function I use (and virtio in qemu-kvm uses as well) is kvm_set_irqfd() that is not qemu.git either. Do I need ifdef these functions with CONFIG_KVM? Please advise as to how to handle these two functions and then I can rebase against qemu.git.
