Comment 2 for bug 1539342

Where is the compute manager code converting an object to a dict?

If _do_live_migration does not get an object for migrate_data, it converts it to one here:

https://github.com/openstack/nova/blob/2d7a851199b12355b36a3982ea0fc7bb5a7cd11f/nova/compute/manager.py#L5174

And then migrate_data (as an object) should be passed down to _rollback_live_migration here:

https://github.com/openstack/nova/blob/2d7a851199b12355b36a3982ea0fc7bb5a7cd11f/nova/compute/manager.py#L5195

And even if _rollback_live_migration gets a dict for migrate_data, it should convert it to an object here:

https://github.com/openstack/nova/blob/2d7a851199b12355b36a3982ea0fc7bb5a7cd11f/nova/compute/manager.py#L5486

Are you saying it's the call to compute rpcapi that's converting it to a dict?
