I don't know how many of our users use boot= today, but it's certainly still in the code, and supported. I honestly wouldn't mind to carry a SUSE specific patch that implements boot= for now until we can deem it deprecated enough that we can drop it. > cpu_set command for CPU hotplug which is known broken in qemu-kvm. > > testdev which is nice but only used for development > > Default nic is rtl8139 vs. e1000. Couldn't we have a machine option that tells us that -M pc-1.2 is really -M pc-kvm-1.2? That way we could implement the device difference, right?
