+
+domain/400-block-pull-abort-info.t - verify the lifecycle of block job:
+block pull, set block job speed, get block job info and abort block job
+
+=head1 DESCRIPTION
+
+The test case validates that it is fine to block pull, set block job speed
+, get block job info and abort block job for domain using qed img with
+qed backing img
