Description
===========
We spawn VM with port-id ,the value of preserve_on_delete is True ,When we lose some ports from instance_info_caches ,after periodic task _heal_instance_info_cache the instance_info_caches are recovery from neutron, however the value of preserve_on_delete became False,not the original value False
Steps to reproduce
==================
1.Spawn VM with command :nova boot --flavor xx --nic port-id xx --image xx instance_name
2.nova interface-list instance_name(Preserve On Delete is True)
3.Update nova db row, drop one interface from interfaces,such as
Update instance_info_caches set network_info='[]' where instance_uuid='xxx';
4.nova show instance_name (we can see ,vm lost network info )
5.after periodic task _heal_instance_info_cache , interface is added to the instance
6.nova interface-list instance_name (Preserve On Delete became False ,not the original value) |
