虚拟机迁移（LiveMigration）时无报错，但虚拟机Host没有变化

Live-Migration时命令行显示正常。
limingfu@control-node:/opt/stack/logs/screen$ vim screen-n-sch.log
limingfu@control-node:/opt/stack/logs/screen$ vim screen-n-sch.log
limingfu@control-node:/opt/stack/logs/screen$ nova live-migration vm1 compute-node-3
limingfu@control-node:/opt/stack/logs/screen$

但虚拟机没有迁移。
