It's not free if the only "free" way to access all qemu's capabilities
from Python requires you to switch all your config files to libvirt's
format and libvirt's way of doing things. There's quite a big jump
from the qemu/kvm way of doing things and the libvirt way, and the
latter isn't well matched to all uses of qemu.

But if libvirt exposes the same QMP as direct to qemu, or something
very similar (it could wrap it, and add it's own libvirt events,
commands and properties), that would be great for scripts that could
then work with either with minimal change.
