The instance is serialized into the build_requests table:
https://github.com/openstack/nova/blob/14.0.1/nova/db/sqlalchemy/api_models.py#L243
From the nova-api log attached to this bug, it looks like the user_data is blowing it up:
https://github.com/openstack/nova/blob/14.0.1/nova/db/sqlalchemy/models.py#L281
Looking at the models, the build_requests.instance column is Text and the instances.user_data is MediumText, so that needs to change.
