Is it feasible (or even useful) to create a library or utility called
"qemu-capabilities", who's sole purpose is to interrogate a qemu
installation and then provide us a list of its capabilities?
This doesn't really solve anything. libvirt already has such a
"library", it is simply part of oura internal API. The problem
is that QEMU itself needs to expose information that does not
currently exist clearly anywhere.
