| * qmp: add block-job-pause and block-job-resumePaolo Bonzini2012-09-281-3/+32
| | | | | | | | | | | | | | | | | | | | | | | | Add QMP commands matching the functionality. Paused jobs cannot be canceled without first resuming them. This ensures that I/O errors are never missed by management. However, an optional force argument can be specified to allow that.

* | hmp: dump-guest-memory: hardcode protocol argument to "file:"Luiz Capitulino2012-09-271-5/+3Star
|/ | | | | | | | | | | | | | | | | | | | Today, it's necessary to specify the protocol you want to use when dumping the guest memory, for example: (qemu) dump-guest-memory file:/tmp/guest-memory This has a few issues: 1. It's cumbersome to type 2. We loose file path autocompletion 3. Being able to specify fd:X in HMP makes little sense for humans Because of these reasons, hardcode the 'protocol' argument to 'file:' in HMP.

* qapi: convert sendkeyAmos Kong2012-09-051-1/+1
| | | | | | | | | | | | | | | | | Convert 'sendkey' to use QAPI. QAPI passes key's index of mapping table to qmp_send_key(), not keycode. So we use help functions to convert key/code to index of key_defs, and 'index' will be converted to 'keycode' inside qmp_send_key(). For qmp, QAPI would check invalid key and raise error. For hmp, invalid key is checked in hmp_send_key(). 'send-key' of QMP doesn't support key in hexadecimal format.

* qapi: convert netdev_addLuiz Capitulino2012-06-041-2/+1Star
| | | | | | | | | | | | | | | | | | | | | 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.

* introduce a new monitor command 'dump-guest-memory' to dump guest's memoryWen Congyang2012-06-041-0/+28
| | | | | | | | | | | | | | | | | | | | | | | | 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 migrateLuiz Capitulino2012-03-151-2/+1Star
| | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
