The QEMUMachine VM has a monitor setup on which an QMP connection is always attempted on _post_launch() (executed by launch()). In case the QEMU process immediatly exits then the qmp.accept() (used to establish the connection) stalls until it reaches timeout and consequently an exception raises. That behavior is undesirable when, for instance, it needs to gather information from the QEMU binary ($ qemu -cpu list) or a test which launches the VM expecting its failure. This patch adds the set_qmp_monitor() method to QEMUMachine that allows turn off the creation of the monitor machinery on VM launch.
