Description
===========
I did live-migration for an instance, error occured by libvirt process.
Then I found field of 'cleaned' was '1' in instances table, but this instance
was not deleted.
Steps to reproduce
==================
* I did live-migrate instance:
$ nova live-migration --block fa0b2b1e-4e00-43bf-bb5d-13ba86277846
* then I found this instance's vm_state was active and instance's host was
still on source compute node.
log is as follow:
