For qemu 1.3, libvirt will NOT be reading '-M ?', but instead calling
the 'query-machines' QMP command.  If you want a machine to be avoided
by libvirt, then perhaps it is best to augment the MachineInfo QMP
datatype to add an optional field that says whether a particular machine
type is stable enough for libvirt's use.
