Kevin Wolf f27a9bb3e9 qmp: Fail gracefully if chardev is already in use ... Trying to attach a QMP monitor to a chardev that is already in use results in a crash because monitor_init_qmp() passes &error_abort to qemu_chr_fe_init(): $ ./x86_64-softmmu/qemu-system-x86_64 --chardev stdio,id=foo --mon foo,mode=control --mon foo,mode=control Unexpected error in qemu_chr_fe_init() at chardev/char-fe.c:220: qemu-system-x86_64: --mon foo,mode=control: Device 'foo' is in use Abgebrochen (Speicherabzug geschrieben) Fix this by allowing monitor_init_qmp() to return an error and passing any error in qemu_chr_fe_init() to its caller instead of aborting.
