Title:
Nova-compute raise exception when vcpu_pin_set is set to None or"".
Status in OpenStack Compute (nova):
Fix Released
Status in OpenStack Compute (nova) newton series:
In Progress
Bug description:
Description
===========
In Mitaka, Nova-compute raise exception when vcpu_pin_set is set to None
or"".And nova-compute fails to start.
Steps to reproduce
==================
Edit vcpu_pin_set=None or vcpu_pin_set=""
then restart nova-compute service
Expected result
===============
Get_vcpu_total returns total_pcpus, and nova-compute service starts
successfully.
Actual result
=============
When set vcpu_pin_set to None, raise following exception and nova-compute
service fails to start:
