If you need to append -config bla, you can also specify the desired NIC
explicitly - I see no value in the former. If we decide to mangle a
qemu-kvm command line before calling QEMU binaries, we can adjust this
variation there. Otherwise it's the same as with all those -kvm*:
Scripts/management tools will need adjustment.
