[Qemu-devel] [PATCH v3 09/10] iotests: Add @has_quit to vm.shutdown()

[Max Reitz]

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.
