If a test has issued a quit command already (which may be useful to do explicitly because the test wants to show its effects), QEMUMachine.shutdown() should not do so again. Otherwise, the VM may well return an ECONNRESET which will lead QEMUMachine.shutdown() to killing it, which then turns into a "qemu received signal 9" line.
