2012-10-24hmp: fix info cpus for sparc targetsAurelien Jarno
On sparc targets, info cpus returns this kind of output: | info cpus | * CPU #0: pc=0x0000000000424d18pc=0x0000000000424d18npc=0x0000000000424d1c thread_id=19460 pc is printed twice, there is no space between pc, pc and npc. With this patch, pc is not printed anymore when has_npc is set. In addition the space is printed before pc/nip/npc/PC instead of after the colon so that multiple prints are possible. This result on the following kind of input on sparc targets: | info cpus | * CPU #0: pc=0x0000000000424d18 npc=0x0000000000424d1c thread_id=19460 Cc: Luiz Capitulino <lcapitulino@redhat.com> Cc: Markus Armbruster <armbru@redhat.com> Cc: Blue Swirl <blauwirbel@gmail.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net> Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
2012-10-24mirror: add support for on-source-error/on-target-errorPaolo Bonzini
Error management is important for mirroring; otherwise, an error on the target (even something as "innocent" as ENOSPC) requires to start again with a full copy. Similar to on_read_error/on_write_error, two separate knobs are provided for on_source_error (reads) and on_target_error (writes). The default is 'report' for both. The 'ignore' policy will leave the sector dirty, so that it will be retried later. Thus, it will not cause corruption.

2012-10-24block: add block-job-completePaolo Bonzini
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. Add a new block job command that manually completes background operations. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2012-09-27qmp: qmp_send_key(): accept key codes in hexLuiz Capitulino
Before the qapi conversion, the sendkey command could be used to send key codes in hex directly to the guest. In HMP, this would be like: (qemu) sendkey 0xdc However, the qapi conversion broke this, as it only supports sending QKeyCode values to the guest. That's a regression. This commit fixes the problem by adding hex value support down the QMP interface, qmp_send_key(). In more detail, this commit: 1. Adds the KeyValue union. This can represent an hex value or a QKeyCode value 2. *Changes* the QMP send-key command to take an KeyValue argument instead of a QKeyCode one 3. Adapt hmp_send_key() to the QMP interface changes Item 2 is an incompatible change, but as we're in development phase (and this command has been merged a few weeks ago) this shouldn't be a problem. Finally, it's not possible to split this commit without breaking the build.

2012-09-27hmp: dump-guest-memory: hardcode protocol argument to "file:"Luiz Capitulino
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.

2012-09-05qapi: convert sendkeyAmos Kong
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.

2012-06-04qapi: convert netdev_addLuiz Capitulino
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.

2012-06-04introduce a new monitor command 'dump-guest-memory' to dump guest's memoryWen Congyang
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.

2012-03-15qapi: Convert migrateLuiz Capitulino
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>
