[Qemu-devel] [PATCH v2 00/12] Migration events + optional sections

[Juan Quintela <quintela@redhat.com>]

Hi

At the end, Daved asked for a couple of things on previous series.

[v2]
- Ensure that we start in NONE even after failed/canceled migration
- move printf's to traces
- make sure that we can migrate the new states like guest-panicked
 (not sure if it is a good idea to enable migrate a guest-panicked, but
 it is not this series the place to forbid it)
- address all comments from Dave and Eric.

Please, review.

[v1]
As the beggining of both series have been accepted, I merged both here.  Changes:
- answered all comments on list and applied suggested changes
- Use migrate_set_state() consistently
- we were misusing atomic_cmpxchg(), it didn't matter until now because
  we were missing only traces, but it showed with events missing.
- Reorganized how the migration events are generated, now only on migrate_set_state.

Please review.




Juan Quintela (12):
  runstate: Add runstate store
  runstate: migration allows more transitions now
  migration: create new section to store global state
  global_state: Make section optional
  vmstate: Create optional sections
  migration: Add configuration section
  migration: Use cmpxchg correctly
  migration: ensure we start in NONE state
  migration: Use always helper to set state
  migration: No need to call trace_migrate_set_state()
  migration: create migration event
  migration: Add migration events on target side
