Title:
Traceback is logged when delete an instance.
Status in OpenStack Compute (Nova):
Fix Released
Bug description:
OpenStack version: Icehouse
Issue: traceback is logged in nova-compute.log when delete an
instance.
Setup: 3 nodes, namely Controller, Compute and Network; with nova-
compute running solely on Compute node.
Steps to reproduce:
1. Create an instance using image cirrus 0.3.2.
2. Verify instance is running: nova list
3. Delete the instance: nova delete <name>
4. Check nova-compute.log at Compute node.
