3. Reproduce steps:
create a new instance from image in cells, then resize or migrate the instance.

Expected result:
resize success

Actual result:
resize failed , Log in the second quarter

4, In the process of the resize/migrate, _resize_cells_support will be
call in nova/compute/api.py. in this func, a migration object will be
create ,but now this object create failed because "without a
migration_type", and leading to the resize/migate fail.

So this is a serious bug If build and use cell environment
