django.db.utils.OperationalError: (1118, 'Row size too large. The maximum row size for the used table type, not counting BLOBs, is 65535. This includes storage overhead, check the manual. You have to change some columns to TEXT or BLOBs')

Start by reproducing the failure with python ./manage.py migrate and review the ec2spotmanager.0013_add_gce_fields migration where MySQL reports the row-size limit. Done means the migration completes without the 65535-byte row-size error; the issue does not identify a target file or prescribed schema change.
