[Qemu-devel] [PATCH 00/22] Migration next

[Juan Quintela <quintela@redhat.com>]

Hi

This includes ram_save_live split + XBZRE changes.

Changes for the previous posts of this series:

ram_save_split:
- recalculate expected_time (Igor).
- Use PRIu64 consistently everywhere

XBZRE:
- rebased on top of previous series
- remove stage3 optimization, now XBZRE don't know about stages
  (code is much simpler)
- reintroduce the stage3(complete) optimization.  We now sent the page
  compressed if the page is on the cache, otherwise, we sent the page
  uncompressed without putting it on the cache.  This is better than
  the previous optimization.

Please review, Juan.

  savevm: Use a struct to pass all handlers
  savevm: Live migration handlers register the struct directly
  savevm: remove SaveSetParamsHandler
  savevm: remove SaveLiveStateHandler
  savevm: Refactor cancel operation in its own operation
  savevm: introduce is_active method
  savevm: split save_live_setup from save_live_state
  savevm: split save_live into stage2 and stage3
  ram: save_live_setup() don't need to sent pages
  ram: save_live_complete() only do one loop
  ram: iterate phase
  ram: save_live_setup() we don't need to synchronize the dirty bitmap.
  ram: save live optimization
