In the v3 series: - Add back the ->shutdown fix Dave found the problem, we need to setup an error if we do shutdown. - Make iotests to work back (we need to setup ->active for savevm) - So postcopy/recovery is fixed again. Please review, if there are not outstanding issues, I plan to push it. Thanks, Juan In the v2 series: - get the multifd test patch - drop the ->shutdown fix it break postcopy recovery test. Still trying to determine if the problem is inside the recover test or the recover code. - upgrade the migrate_cancel test Please review. [v1] This series: - create a test that does: launch multifd on target migrate to target cancel on source create another target migrate again - And fixes the cases that made it fail: * Make sure that we don't try ever IO after shutdown/error Please, review. Juan Quintela (6): migration-test: Use g_free() instead of free() multifd: Make sure that we don't do any IO after an error qemu-file: Don't do IO after shutdown migration-test: Make sure that multifd and cancel works migration: Create migration_is_running() migration: Don't send data if we have stopped migration/migration.c | 29 +++++++-- migration/migration.h | 1 + migration/qemu-file.c | 22 ++++++- migration/ram.c | 23 ++++--- migration/savevm.c | 4 +- tests/qtest/migration-test.c | 114 ++++++++++++++++++++++++++++++++++- 6 files changed, 173 insertions(+), 20 deletions(-) --=20 2.24.1
