```

Start by reproducing the failure with demos/example_aliyun_ecs.py using Libcloud 3.5.1, then inspect the create_node call in libcloud/compute/drivers/ecs.py and the instance-type parameters it sends. Done means determining whether the example or Aliyun ECS driver is responsible for the InstanceType.Offline response and identifying the relevant change.
