[PATCH 0/5] Restore vmstate on cancelled/failed migration

[Vladimir Sementsov-Ogievskiy]

Hi all.

The problem I want to solve is that guest-panicked state may be lost
when migration is failed (or cancelled) after source stop.

Still, I try to go further and restore all possible paused states in the
same way. The key patch is the last one and others are refactoring and
preparation.

Vladimir Sementsov-Ogievskiy (5):
  runstate: add runstate_get()
  migration: never fail in global_state_store()
  runstate: drop unused runstate_store()
  migration: switch from .vm_was_running to .vm_old_state
  migration: restore vmstate on migration failure
