It is not practical to use QMP with any 0.12.x version of QEMU. The
0.13.x release series will be the first where it is complete enough
to use. Current GIT code is getting reasonably complete - waiting for
netdev_add/del to be merged, and then blockdev_add/del will complete
the functionality for device hotplug use cases.
