qemu-char: Saner naming of memchar stuff & doc fixes New device, has never been released, so we can still improve things without worrying about compatibility. Naming is a mess. The code calls the device driver CirMemCharDriver, the public API calls it "memory", "memchardev", or "memchar", and the special commands are named like "memchar-FOO". "memory" is a particularly unfortunate choice, because there's another character device driver called MemoryDriver. Moreover, the device's distinctive property is that it's a ring buffer, not that's in memory. Therefore: * Rename CirMemCharDriver to RingBufCharDriver, and call the thing a "ringbuf" in the API. * Rename QMP and HMP commands from memchar-FOO to ringbuf-FOO. * Rename device parameter from maxcapacity to size (simple words are good for you). * Clearly mark the parameter as optional in documentation. * Fix error reporting so that chardev-add reports to current monitor, not stderr. * Replace cirmem in C identifiers by ringbuf. * Rework documentation. Document the impact of our crappy UTF-8 handling on reading. * QMP examples that even work. I could split this up into multiple commits, but they'd change the same documentation lines multiple times. Not worth it. Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

qapi: Convert blockdev_snapshot_sync Unfortunately, this conversion required an additional change. In the old QMP command, the 'snapshot-file' argument is specified as optional. The idea is to take the snapshot internally if 'snapshot-file' is not passed. However, internal snapshots are not supported yet so the command returns a MissingParamater error if 'snapshot-file' is not passed. Which makes the argument actually required and will cause compatibility breakage if we change that in the future. To fix this the QAPI converted blockdev_snapshot_sync command makes the 'snapshot-file' argument required. Again, in practice it's actually required, so this is not incompatible. If we do implement internal snapshots someday, we'll need a new argument for it. Note that this discussion doesn't affect HMP. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>

block: add block-job-complete While streaming can be dropped as soon as it progressed through the whole image, mirroring needs to be completed manually for two reasons: 1) so that management knows exactly when the VM switches to the target; 2) because for other use cases such as replication, we may leave the operation running for the whole life of the virtual machine.

qapi: Convert migrate The migrate command is one of those commands where HMP and QMP completely mix up together. This made the conversion to the QAPI (which separates the command into QMP and HMP parts) a bit difficult. The first important change to be noticed is that this commit completes the removal of the Monitor object from migration code, started by the previous commit. Another important and tricky change is about supporting the non-detached mode. That is, if the user doesn't pass '-d' the migrate command will lock the monitor and will only release it when migration is finished. To support this in the new HMP command (hmp_migrate()), it is necessary to create a timer which runs every second and checks if the migration is still active. If it is, the timer callback will re-schedule itself to run one second in the future. If the migration has already finished, the monitor lock is released and the user can use it normally. All these changes should be transparent to the user. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>

introduce a new monitor command 'dump-guest-memory' to dump guest's memory The command's usage: dump-guest-memory [-p] protocol [begin] [length] The supported protocol can be file or fd: 1. file: the protocol starts with "file:", and the following string is the file's path. 2. fd: the protocol starts with "fd:", and the following string is the fd's name. Note: 1. If you want to use gdb to process the core, please specify -p option. The reason why the -p option is not default is: a. guest machine in a catastrophic state can have corrupted memory, which we cannot trust. b. The guest machine can be in read-mode even if paging is enabled. For example: the guest machine uses ACPI to sleep, and ACPI sleep state goes in real-mode. 2. If you don't want to dump all guest's memory, please specify the start physical address and the length.

qapi: convert netdev_add This is not a full QAPI conversion, but an intermediate step. In essence, do_netdev_add() is split into three functions: 1. netdev_add(): performs the actual work. This function is fully converted to Error (thus, it's "qapi-friendly") 2. qmp_netdev_add(): the QMP front-end for netdev_add(). This is coded by hand and not auto-generated (gen=no in the schema). The reason for this it's a lot easier and simpler to with QemuOpts this way 3. hmp_netdev_add(): HMP front-end. This design was suggested by Paolo Bonzini.
