Agreed. Not relying on Mata Hari and reinventing a dbus/WMI interface
would be yet another case of QEMU NIH. The same argument also works on
the backend BTW, it can be virtio serial but also a Xen pvconsole and
that wheel should not be reinvented either.

The guest agent should be a pluggable architecture, and QEMU can provide
plugins for sync, spice, "info balloon" and everything else it needs.
