2012-04-27block: add 'speed' optional parameter to block-streamStefan Hajnoczi
Allow streaming operations to be started with an initial speed limit. This eliminates the window of time between starting streaming and issuing block-job-set-speed. Users should use the new optional 'speed' parameter instead so that speed limits are in effect immediately when the job starts.

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>

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>

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.

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.
