Even though a "QMP bus" could be useful, I don't think there is anything
like that at the moment.
Also considering that each qemu instance takes care of a single guest,
the usefulness of such a mechanism is reduced.
Anyhow in this particular case using QMP seems appropriate: I would
welcome patches to add QMP support to libxenlight, even though I realize
that it is a bigger effort than this single patch.
