      monitor: Decouple terminals (Jan Kiszka) · 731b0364
      aliguori authored
      Currently all registered (and activate) monitor terminals work in
      broadcast mode: Everyone sees what someone else types on some other
      terminal and what the monitor reports back. This model is broken when
      you have a management monitor terminal that is automatically operated
      and some other terminal used for independent guest inspection. Such
      additional terminals can be multiplexed device channels or a gdb
      frontend connected to QEMU's stub.
      
      Therefore, this patch decouples the buffers and states of all monitor
      terminals, allowing the user to operate them independently. It finally
      starts to use the 'mon' parameter that was introduced earlier with the
      API rework. It also defines the default monitor: the first instantance
      that has the MONITOR_IS_DEFAULT flag set, and that is the monitor
      created via the "-monitor" command line switch (or "vc" if none is
      given).
      
      As the patch requires to rework the monitor suspension interface, it
      also takes the freedom to make it "truely" suspending (so far suspending
      meant suppressing the prompt, but inputs were still processed).

      monitor: Rework API (Jan Kiszka) · 376253ec
      aliguori authored
      Refactor the monitor API and prepare it for decoupled terminals:
      term_print functions are renamed to monitor_* and all monitor services
      gain a new parameter (mon) that will once refer to the monitor instance
      the output is supposed to appear on. However, the argument remains
      unused for now. All monitor command callbacks are also extended by a mon
      parameter so that command handlers are able to pass an appropriate
      reference to monitor output services.
      
      For the case that monitor outputs so far happen without clearly
      identifiable context, the global variable cur_mon is introduced that
      shall once provide a pointer either to the current active monitor (while
      processing commands) or to the default one. On the mid or long term,
      those use case will be obsoleted so that this variable can be removed
      again.
      
      Due to the broad usage of the monitor interface, this patch mostly deals
      with converting users of the monitor API. A few of them are already
      extended to pass 'mon' from the command handler further down to internal
      functions that invoke monitor_printf.
      
      At this chance, monitor-related prototypes are moved from console.h to
      a new monitor.h. The same is done for the readline API.

      Introduce TCP live migration protocol · 34c9dd8e
      aliguori authored
      This patch introduces a tcp protocol for live migration.  It can be used as
      follows:
      
      qemu-system-x86_64 -hda ~/images/linux-test.img -monitor stdio
       <vm runs for a while>
      (qemu) migrate tcp:localhost:1025
      
      On the same system:
      
      qemu-system-x86_64 -hda ~/images/linux-test.img -incoming 
      tcp:localhost:1025
      
      The monitor can be interacted with while waiting for an incoming live 
      migration.
