migrate_fd_cleanup will usually close the file descriptor via buffered_file_close's call to migrate_fd_close. However, in the case of s->file == NULL it is "inlining" migrate_fd_close (almost: there is a direct close() instead of using s->close(s)). To fix the inconsistency and clean up the code, allow multiple calls to migrate_fd_close and use the function in migrate_fd_cleanup. Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com>

At the end of migration the machine has started already, and cannot be destroyed without losing the guest's data. Hence, prelaunch is the wrong state. Go to the paused state instead. QEMU would reach that state anyway (after running the guest for the blink of an eye) if the "stop" command had been received after the start of migration.

Error propagation is already there for socket backends. Add it to other protocols, simplifying code that tests for errors that will never happen. With all protocols understanding Error, the code can be simplified further by removing the return value. Unfortunately, the quality of error messages varies depending on where the error is detected, because no Error is passed to the NonBlockingConnectHandler. Thus, the exact error message still cannot be sent to the user if the OS reports it asynchronously via SO_ERROR. If NonBlockingConnectHandler received an Error**, we could for example report the error class and/or message via a new field of the query-migration command even if it is reported asynchronously. Before: (qemu) migrate fd:ffff migrate: An undefined error has occurred (qemu) info migrate (qemu) After: (qemu) migrate fd:ffff migrate: File descriptor named 'ffff' has not been found (qemu) info migrate capabilities: xbzrle: off Migration status: failed total time: 0 milliseconds Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com>

The migration code is using errp to detect "internal" errors, this means that it relies on errp being non-NULL. No impact so far because our only QMP clients (the QMP marshaller and HMP) never pass a NULL Error **. But if we had others, this patch would make sure that migration can work with a NULL Error **.

Use help functions in qemu-socket.c for tcp migration, which already support ipv6 addresses. Currently errp will be set to UNDEFINED_ERROR when migration fails, qemu would output "migration failed: ...", and current user can see a message("An undefined error has occurred") in monitor. This patch changed tcp_start_outgoing_migration()/inet_connect() /inet_connect_opts(), socket error would be passed back, then current user can see a meaningful err message in monitor. Qemu will exit if listening fails, so output socket error to qemu stderr. For IPv6 brackets must be mandatory if you require a port. Referencing to RFC5952, the recommended format is: [2312::8274]:5200 test status: Successed listen side: qemu-kvm .... -incoming tcp:[2312::8274]:5200 client side: qemu-kvm ...
