`nova migrate` do not preserve the data within instance. It start fresh instance on destination compute node.
Issue
- When using
nova migrateto move an instance from a node that is backed by a filesystem to a node that is backed by CEPH, the command completes successfully. However, the actual instance no longer contains the correct data - it is replaced with the data from a fresh copy of the image the instance was built with. The file that backed the VM was correctly migrated (via rsync), but then left on the filesystem of the Ceph-backed node, and not uploaded into the Ceph pool.
