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 include/migration/global_state.h | 2 +- include/sysemu/runstate.h | 2 +- migration/global_state.c | 23 +++++++------ migration/migration.c | 56 +++++++++++++++----------------- migration/migration.h | 9 +++-- migration/savevm.c | 6 +--- softmmu/runstate.c | 25 +++++++------- 7 files changed, 59 insertions(+), 64 deletions(-) -- 2.34.1
