The thinking with Matahari is that there is significant overlap between
agent requirements for a physical and virtual host, so it aims to provide
an agent that works everywhere, whether virtualized or not. All that need
change is the communication transport (TCP vs VirtIO Serial vs legacy
serial vs some other data channel), and enable/disable certain agent
services according to deployment scenario. Once you go to a more general
purpose agent in this way, then it doesn't make such sense to put it all
in the QEMU tree.
