Failed delete SecurityGroupRule if fail during 'Delete secgroup rule in Nova'

[Yitao Jiang]

Bug Reproduce:
firstly, create secgroup rule using trove-cli add_rule;
secondly, delete the secgroup rule using nova secgroup-delete-rule;
lastly, using trove-cli secgroup delete_rule to delete the same rule,
and in trove-api.log, you can see the exceptions below:

I dont't know whether it is a bug.

It's not a bug, since you can interact with any of OS components you could do anything you want. That is why i think it's a wrong resource management.
