Hello, I am trying to deploy openstack on three nodes - (1) controller node, (2) compute node and (3) network node. I am working on CentOS and following this tutorial https://access.redhat.com/site/documentation/en-US/Red_Hat_OpenStack/3/pdf/I... Now I am configuring Network Node. Network configuration starts at page 92. Firstly I would like to run quantum-server so I did everything from page 92 to 105. But something is not working. When I do " service quantum-server restart" the result is Stopping quantum: [FAILED] Starting quantum: [ OK ] And it happens all the time, that means that quantum-server works only a short period of time and it comes dead. *When I do* quantum-server --config-file /etc/quantum/quantum.conf --debug --verbose *the logs are as follows* INFO [quantum.service] Quantum service started, listening on 0.0.0.0:9696 2013-08-21 17:50:14 DEBUG [qpid.messaging.io.raw] SENT[2775e60]: '\x0f\x01\x00\x19\x00\x01\x00\x00\x00\x00\x00\x00\x04\n\x01\x00\x07\x00\x010\x01\xff\xff\xff\xff\x0f\x01\x00\ x19\x00\x01\x00\x00\x00\x00\x00\x00\x04\n\x01\x00\x07\x00\x010\x00\x00\x00\x00\x01' 2013-08-21 17:51:13 DEBUG [qpid.messaging.io.ops] SENT[2775e60]: ConnectionHeartbeat() 2013-08-21 17:51:13 DEBUG [qpid.messaging.io.raw] SENT[2775e60]: '\x0f\x00\x00\x10\x00\x00\x00\x00\x00\x00\x00\x00\x01\n\x00\x00' 2013-08-21 17:51:13 DEBUG [qpid.messaging.io.raw] READ[2775e60]: '\x0f\x00\x00\x10\x00\x00\x00\x00\x00\x00\x00\x00\x01\n\x00\x00' 2013-08-21 17:51:13 DEBUG [qpid.messaging.io.ops] RCVD[2775e60]: ConnectionHeartbeat() 2013-08-21 17:52:13 DEBUG [qpid.messaging.io.ops] SENT[2775e60]: ConnectionHeartbeat() 2013-08-21 17:52:13 DEBUG [qpid.messaging.io.raw] SENT[2775e60]: '\x0f\x00\x00\x10\x00\x00\x00\x00\x00\x00\x00\x00\x01\n\x00\x00' 2013-08-21 17:52:13 DEBUG [qpid.messaging.io.raw] READ[2775e60]: '\x0f\x00\x00\x10\x00\x00\x00\x00\x00\x00\x00\x00\x01\n\x00\x00' 2013-08-21 17:52:13 DEBUG [qpid.messaging.io.ops] RCVD[2775e60]: ConnectionHeartbeat() **that means that something is working.
