Hi every one, Can any one spot why the following bug will appear in Openstack leaving all services of Neutron to unusable state....?
To give you an idea that I was trying: "I tried to configure 173.39.237.0 ip to a VM, with the CIDR 173.39.236.0/23, however the OVS gave error and now all the neutron services are completely unusable" 2015-02-04 05:25:06.993 TRACE neutron.plugins.openvswitch.agent.ovs_neutron_agent Traceback (most recent call last): 2015-02-04 05:25:06.993 TRACE neutron.plugins.openvswitch.agent.ovs_neutron_agent File "/opt/stack/neutron/neutron/plugins/openvswitch/agent/ovs_neutron_agent.py", line 1197, in rpc_loop 2015-02-04 05:25:06.993 TRACE neutron.plugins.openvswitch.agent.ovs_neutron_agent port_info = self.scan_ports(ports, updated_ports_copy) 2015-02-04 05:25:06.993 TRACE neutron.plugins.openvswitch.agent.ovs_neutron_agent File "/opt/stack/neutron/neutron/plugins/openvswitch/agent/ovs_neutron_agent.py", line 821, in scan_ports 2015-02-04 05:25:06.993 TRACE neutron.plugins.openvswitch.agent.ovs_neutron_agent updated_ports.update(self.check_changed_vlans(registered_ports)) 2015-02-04 05:25:06.993 TRACE neutron.plugins.openvswitch.agent.ovs_neutron_agent File "/opt/stack/neutron/neutron/plugins/openvswitch/agent/ovs_neutron_agent.py", line 848, in check_changed_vlans 2015-02-04 05:25:06.993 TRACE neutron.plugins.openvswitch.agent.ovs_neutron_agent port_tags = self.int_br.get_port_tag_dict() 2015-02-04 05:25:06.993 TRACE neutron.plugins.openvswitch.agent.ovs_neutron_agent File "/opt/stack/neutron/neutron/agent/linux/ovs_lib.py", line 394, in get_port_tag_dict 2015-02-04 05:25:06.993 TRACE neutron.plugins.openvswitch.agent.ovs_neutron_agent result = self.run_vsctl(args, check_error=True) 2015-02-04 05:25:06.993 TRACE neutron.plugins.openvswitch.agent.ovs_neutron_agent File "/opt/stack/neutron/neutron/agent/linux/ovs_lib.py", line 67, in run_vsctl 2015-02-04 05:25:06.993 TRACE neutron.plugins.openvswitch.agent.ovs_neutron_agent return utils.execute(full_args, root_helper=self.root_helper) 2015-02-04 05:25:06.993 TRACE neutron.plugins.openvswitch.agent.ovs_neutron_agent File "/opt/stack/neutron/neutron/agent/linux/utils.py", line 75, in execute 2015-02-04 05:25:06.993 TRACE neutron.plugins.openvswitch.agent.ovs_neutron_agent raise RuntimeError(m) 2015-02-04 05:25:06.993 TRACE neutron.plugins.openvswitch.agent.ovs_neutron_agent RuntimeError: 2015-02-04 05:25:06.993 TRACE neutron.plugins.openvswitch.agent.ovs_neutron_agent Command: ['sudo', '/usr/local/bin/neutron-rootwrap', '/etc/neutron/rootwrap.conf', 'ovs-vsctl', '--timeout=10', '--format=json', '--', '--columns=name,tag', 'list', 'Port'] 2015-02-04 05:25:06.993 TRACE neutron.plugins.openvswitch.agent.ovs_neutron_agent Exit code: 1 2015-02-04 05:25:06.993 TRACE neutron.plugins.openvswitch.agent.ovs_neutron_agent Stdout: '' 2015-02-04 05:25:06.993 TRACE neutron.plugins.openvswitch.agent.ovs_neutron_agent Stderr: 'Traceback (most recent call last):\n File "/usr/local/bin/neutron-rootwrap", line 4, in <module>\n __import__(\'pkg_resources\').require(\'neutron==2013.2.4.dev32\')\n File "/usr/local/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 3018, in <module>\n working_set = WorkingSet._build_master()\n File "/usr/local/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 614, in _build_master\n return cls._build_from_requirements(__requires__)\n File "/usr/local/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 627, in _build_from_requirements\n dists = ws.resolve(reqs, Environment())\n File "/usr/local/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 805, in resolve\n raise DistributionNotFound(req)\npkg_resources.DistributionNotFound: alembic<0.6.4,>=0.4.1\n' 2015-02-04 05:25:06.993 TRACE neutron.plugins.openvswitch.agent.ovs_neutron_agent
