Title:
Bug: migrate instance after delete flavor
Status in OpenStack Compute (nova):
Expired
Bug description:
Error occured when migrate instance after delete flavor.
Reproduce step :
1. create flavor A
2. boot instance using flavor A
3. delete flavor A
4. migrate instance (ex : nova migrate [instance_uuid])
5. Error occured

This Error is occured when resize_instance method is called as below code:
/opt/openstack/src/nova/nova/compute/manager.py
def resize_instance(self, context, instance, image,
reservations, migration, instance_type,
clean_shutdown=True):
....
if (not instance_type or
not isinstance(instance_type, objects.Flavor)):
instance_type = objects.Flavor.get_by_id(
context, migration['new_instance_type_id'])
....
context parameter has this data:

When objects.Flavor.get_by_id method is called, error is occurred because the
default value of read_deleted is "no".
So, I think context.read_deleted attribute should be set to "yes" before
objects.Flavor.get_by_id method is called.
I've tested this using stable/kilo and I think liberty, mitaka has
same problem.
Thanks.
