Hello, I am running into an issue creating a VM instance (RPC message timeout in nova-network). I have a few questions about the following entires in nova-api.log file:
1) 2012-11-18 15:50:27 DEBUG nova.openstack.common.rpc.amqp [-] Making asynchronous call on network ... from (pid=1688) multicall /usr/lib/python2.7/dist-packages/nova/openstack/common/rpc/amqp.py:351 2) 2012-11-18 15:50:27 DEBUG nova.openstack.common.rpc.amqp [-] MSG_ID is 4b1f8e549f1448589d9d35b7eb4b6364 from (pid=1688) multicall /usr/lib/python2.7/dist-packages/nova/openstack/common/rpc/amqp.py:354 3) 2012-11-18 15:50:28 DEBUG nova.compute.api [req-f2b4df1f-6c29-48dc-991b-93fb5eb29d08 ce016bb05df949ebbafcc7c165359d7c ce1e819636744dc680fa5515f6475e87] Going to run 1 instances... from (pid=1688) _create_instance /usr/lib/python2.7/dist-packages/nova/compute/api.py:490 4) 2012-11-18 15:50:28 DEBUG nova.openstack.common.rpc.amqp [-] Making asynchronous cast on scheduler... from (pid=1688) cast /usr/lib/python2.7/dist-packages/nova/openstack/common/rpc/amqp.py:376 Questions: - Is log message 1 and 4 related to nova-api sending a message to nova-network and nova-scheduler through the rabbitmq queue server? - I have a two node setup, one controller-node (on which no nova-compute running) and one compute-node (on which nova-compute is running). Who/which service on which node is printing log message 3. The reason I ask is because log message 3 is prefixed with "nova.compute.api", but I feel at this point no message has reached nova-compute service on compute-node. - The MSG_ID in log message 2 pertains to which message? - Out of curiosity, what is the difference between "Making asynchronous call" (log message 1) vs. "Making asynchronous cast" (log message 2). Any info in understanding the log messages would be highly appreciated. Thank you, Ahmed.
