Public bug reported: If all compute nodes in some availability zone are disabled, horizon trace at availability zones list.
Steps to reproduce: 1. Create host aggregate and availability zone (nova aggreage-create some some) 2. Add some (at least one) host to that host aggregate (nova aggreage-add-host some compute_host) 3. Disable service at all compute_hosts (nova service-disable compute_host nova-compute) 4. Go to (in dashboard) Admin -> System Info -> Availability Zones Expected result: Output with list of availabilizy zones Actual Result: TemplateSyntaxError at /admin/info/ 'NoneType' object has no attribute 'items' Request Method: GET Request URL: http://78.140.137.204/horizon/admin/info/ Django Version: 1.5.4 Exception Type: TemplateSyntaxError Exception Value: 'NoneType' object has no attribute 'items' Exception Location: /usr/share/openstack-dashboard/openstack_dashboard/wsgi/../../openstack_dashboard/dashboards/admin/info/tables.py in get_hosts, line 60 Python Executable: /usr/bin/python Python Version: 2.7.3 Python Path: ['/usr/share/openstack-dashboard/openstack_dashboard/wsgi/../..', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-linux2', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages', '/usr/share/openstack-dashboard/', '/usr/share/openstack-dashboard/openstack_dashboard'] Server time: Wed, 26 Mar 2014 15:53:32 +0000 P.
