Is failed on step 3 with error ROLLBACK_FAILED.
Stack is created with following template:
description: 'Template which creates single instance
'
heat_template_version: '2013-05-23'
outputs:
servers:
value: {get_resource: Server}
parameters:
ImageId: {type: string}
InstanceType: {type: string}
network: {type: string}
resources:
port:
type: OS::Neutron::Port
properties:
network: {get_param: network}
Server:
properties:
flavor: {get_param: InstanceType}
flavor_update_policy: REPLACE
image: {get_param: ImageId}
name: ost1-test_heat
networks:
- network: {Ref: port}
type: OS::Nova::Server
During update the instance type is changed from tiny to small

The same bug was reproduced with template, where used just network property. In this case nova will create port in neutron.
During update replace heat detaches ports and it has downside for nova created ports - they will be deleted by nova during this detach operation.
So we need to handle this case separately and try to attach new port after cancel-update as it was done by nova.
