<DIV>we are running Havana (2013.2.3 )(provider network/ovs bridge/dhcp/dnsmasq)¡£</DIV>
<DIV>It is running well in the past .</DIV>
<DIV>But today something broken , when creating a new vm , the vm was created successfully , but vm network failed.</DIV>
<DIV> </DIV>
<DIV>I see "cloud-init-nonet waiting 120 seconds for a network device." via nova console-log vmid.</DIV>
<DIV>vm did not get ip via dhcp.</DIV>
<DIV>I tried to ifconfig the vm manually via vnc , but it did not work either. </DIV>
<DIV> </DIV>
<DIV>There is error log in /var/log/neutron/openvswitch-agent.log:</DIV>
<DIV>ERROR neutron.plugins.openvswitch.agent.ovs_neutron_agent [-] Error in agent event loop</DIV>
<DIV>Timeout while waiting on RPC response - topic: "q-plugin", RPC method: "security_group_rules_for_devices" info: "<unknown>"</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>There are lots of message which are not comsumed in q-plugin queue in rabbitmq.</DIV>
<DIV>The numbers of message in q-plugin queue is getting more and more .</DIV>
<DIV>root@rise-mq-27:~# rabbitmqctl list_queues -p /13fa9ce55 name durable messages |grep q-plugin </DIV>
<DIV>q-plugin false 135269</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>My questions are :</DIV>
<DIV>1. Does the q-plugin lead to the vm network failture?</DIV>
<DIV>2. if so , who are the comsumer of q-plugin , how I can make them comsume again?</DIV>
<DIV>3. it is said that it will skip "q-plugin" RPC timeout issue if disabling security group .</DIV>
<DIV> I've read this post https://ask.openstack.org/en/question/9592/disabling-security-groups-in-horizon/</DIV>
<DIV> and wonder whether I should edit both(nova and neutron) configuration files only in HV </DIV>
<DIV> or also in nova/neutron server (controller)?</DIV>
<DIV> </DIV>
<DIV>Thank you .</DIV></DIV>
