Problem is, without a libqemu, libvirt cannot return a QMPContext that
can be used by python bindings. This is the problem that all high
level languages have with respect to RPC transports.
You need libqemu to deal with establishing the transport. That code
needs to be common and shared across languages.
We can't libvirt talk QMG with Python over a pipe or local socket?
So that the Python can talk to native qemu and via libvirt with the
same code.
That would be much easier from Python person than writing a wrapper
around the C library. Multiplied by each high-level language...
