[PATCH 1/2] tests: add migrate-during-backup |
Date: |
Fri, 10 Sep 2021 14:00:59 +0300 |
Add a simple test which tries to run migration during backup.
bdrv_inactivate_all() should fail. But due to bug (see next commit with
fix) it doesn't, nodes are inactivated and continued backup crashes
on assertion "assert(!(bs->open_flags & BDRV_O_INACTIVE));" in
bdrv_co_write_req_prepare().
