[Bug 2072623] [NEW] os-hypervisors detail api throws 500

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:


Summary:
os-hypervisors detail api throws 500

Description
===========

After stopping compute service in one of the compute node, if we look
for hypervisor list for compute status, its returning 500, howerever it
should tell which hypervisor is up and down.

The API wait and try to retrieve (polling), but eventually its fails
with 500, as it could not get info on particular node.


Steps to reproduce
==================
- stop a compute service in one of the compute node
- run openstack hypervisor list


Expected result
===============

Service status should be shown down

$ openstack hypervisor list
