Steps to reproduce
==================
Attached iscsi volume to an instance. Do live_migration and restart libvirt after nova's pre_live_migration.

Expected result

Aborted live_migration, rollback nova's bdm info and cinder's attachment.

Actual result
=============
nova's bdm and cinder's attachment record destination node connection_info.
