Hi Trinath,
One possibility is that you've mismatched versions of nova core
(specifically the DB schema) and nova volume.
The volumes.instance_id column exists in the Essex schema, but was
later dropped and replaced with an instance_uuid column (to reflect
the foreign key type changing from int to UUID-as-varchar).
Have you run a DB sync to up the schema version beyond Essex (i.e.
past migration index 82)?
Cheers,
Eoghan
