Open Stack

You're missing a package I'm guessing, although this is working for us and I don't think we've made any major mods to puppet-neutron. Unfortunately its one of the areas I've not worked on re: puppet. Based on the python2.6 below I guess you're on RedHat? so my packages and experience may not translate well. Maybe python-neutron is needed?

Subject: [Openstack-operators] neutron wont start

hi guys,

am working on installing neutron (via puppet) but it just wont start and fails, when I try to track down the culprit, I end up with :

 # neutron-db-manage --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/plugin.ini current
No handlers could be found for logger "neutron.common.legacy"
Traceback (most recent call last):
  File "/usr/bin/neutron-db-manage", line 10, in <module>
    sys.exit(main())
  File "/usr/lib/python2.6/site-packages/neutron/db/migration/cli.py", line 143, in main

    importutils.import_class(class_path)

    traceback.format_exception(*sys.exc_info())))
ImportError: Class openvswitch cannot be found (['Traceback (most recent call last):\n', '  File "/usr/lib/python2.6/site-packages/neutron/openstack/common/importutils.py", line 30, in import_class\n    __import__(mod_str)\n', 'ValueError: Empty module name\n'])


The puppet module currently does :


  class { 'neutron':
    rabbit_host     => $amqhost,
    rabbit_user     => $amquser,
    rabbit_password => $amqpass,
  }

  class { 'neutron::server':
    database_connection => "mysql://${neutrondbuser}:${neutrondbpass}@${neutrondbhost}/ovs_neutron?charset=utf8",
    auth_host           => $auth_host,
    auth_user           => $neutronadminuser,
    auth_password       => $neutronadminpass,
  }

  class { 'neutron::plugins::ovs':
    tenant_network_type => 'local',
    network_vlan_ranges => 'br100:1:1',
  }

  class { 'neutron::agents::ovs':
    bridge_mappings => ['br100:br100'],
  }

Anyone know what I'm missing ?

Thanks for your help!
Alex
