[Bug 1794647] [NEW] unnecessary inst_base was created
Public bug reported:
Description
===========
When migrating to other hosts, if inst_base is on shared storage, it will recreate inst_base after moving inst_base to inst_base_resize. But rbd backend is treated as shared storage too, it will create inst_base on source host also. In this situation, even if the resize finished, the inst_base on source host will still exist. This wll trigger errors when live-migration to the source host.
