2012-01-26qmp: add block_job_cancel commandStefan Hajnoczi
Add block_job_cancel, which stops an active block streaming operation. When the operation has been cancelled the new BLOCK_JOB_CANCELLED event is emitted.

2012-01-26qmp: add block_stream commandStefan Hajnoczi
Add the block_stream command, which starts copy backing file contents into the image file. Also add the BLOCK_JOB_COMPLETED QMP event which is emitted when image streaming completes. Later patches add control over the background copy speed, cancelation, and querying running streaming operations.

2012-01-04Expose drive_add on all architecturesAlexander Graf
All architectures can now use drive_add on the monitor. This of course does not mean that there is hotplug support for the specific platform, so in order to actually make use of the new drives you still need to have a hotplug capable device. Signed-off-by: Alexander Graf <agraf@suse.de>

2011-12-06qapi: Convert blockdev_snapshot_syncLuiz Capitulino
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>

Note that the command being dropped uses the deprecated MONITOR_CMD_ASYNC API, but the new command is a regular synchronous command.

2011-12-05block: add -drive copy-on-read=on|offStefan Hajnoczi
This patch adds the -drive copy-on-read=on|off command-line option: copy-on-read=on|off copy-on-read is "on" or "off" and enables whether to copy read backing file sectors into the image file. Copy-on-read avoids accessing the same backing file sectors repeatedly and is useful when the backing file is over a slow network. By default copy-on-read is off.

2011-10-25spice: turn client_migrate_info to asyncYonit Halperin
RHBZ 737921 Spice client is required to connect to the migration target before/as migration starts. Since after migration starts, the target qemu is blocked and cannot accept new spice client we trigger the connection to the target upon client_migrate_info command. client_migrate_info completion cb will be called after spice client has been connected to the target (or a timeout).

2011-09-01trace: always compile support for controlling and querying trace event statesLluís

2011-07-21QMP: add snapshot-blkdev-sync commandJes Sorensen
Add QMP bits for snapshot_blkdev command. This is the same as snapshot_blkdev in the human monitor. The command is synchronous. In the future async commands and or a break down of the functionality into multiple commands might be added. Also change the 'snapshot_file' argument to 'snapshot-file' in the human monitor, so that it matches QMP.

2011-06-01HMP: Use QMP inject nmi implementationLuiz Capitulino
This **CHANGES** the human monitor "nmi" command behavior. Currently it accepts an CPU argument which, when provided, will send the NMI to the specified CPU. This feature is of discussable value though and HMP shouldn't have more features than QMP, so let's use QMP's instead (it's also simpler). Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>

2011-01-31block: add block_resize monitor commandChristoph Hellwig
Add a monitor command that allows resizing of block devices while qemu is running. It uses the existing bdrv_truncate method already used by qemu-img to do it's work. Compared to qemu-img the size parsing is very simplicistic, but I think having a properly numering object is more useful for non-humand monitor users than having the units and relative resize parsing. For SCSI devices the new size can be updated in Linux guests by doing the following shell command: echo > /sys/class/scsi_device/0:0:0:0/device/rescan For ATA devices I don't know of a way to update the block device size in Linux system, and for virtio-blk the next two patches will provide an automatic update of the size when this command is issued on the host.

2011-01-24spice/vnc: client migration.Gerd Hoffmann
Handle spice client migration, i.e. inform a spice client connected about the new host and connection parameters, so it can move over the connection automatically. The monitor command has a not-yet used protocol argument simliar to set_password and expire_password commands. This allows to add a simliar feature to vnc in the future. Daniel Berrange plans to work on this. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-01-21Add "broadcast" option for mce commandJin Dongming
When the following test case is injected with mce command, maybe user could not get the expected result. DATA command cpu bank status mcg_status addr misc (qemu) mce 1 1 0xbd00000000000000 0x05 0x1234 0x8c Expected Result panic type: "Fatal Machine check" That is because each mce command can only inject the given cpu and could not inject mce interrupt to other cpus. So user will get the following result: panic type: "Fatal machine check on current CPU" "broadcast" option is used for injecting dummy data into other cpus. Injecting mce with this option the expected result could be gotten. Usage: Broadcast[on] command broadcast cpu bank status mcg_status addr misc (qemu) mce -b 1 1 0xbd00000000000000 0x05 0x1234 0x8c Broadcast[off] command cpu bank status mcg_status addr misc (qemu) mce 1 1 0xbd00000000000000 0x05 0x1234 0x8c Signed-off-by: Jin Dongming <jin.dongming@np.css.fujitsu.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
