Hi Florian I observed this kind of issue when there is race condition.
1. RabbitMQ is NOT running on controller-node 2. You issue nova-network from compute-node. Now this step hangs. 3. Just see what is happening in nova-api.log on controller(tail -f /var/log/nova/nova-api.log) 4. Now you start the RabbitMQ on the controller node. 5. nova-network command compute returns the error. Also you will see 'timeout' error in nova-api.log. >From your log I suspect this because initially RabitMQ was not up. Looks like you started it afterwards. Did you try to run the same 'nova-network' command for the second time ? i.e after restarting the rabbitMQ ? -Dheerendra On Wed, Oct 30, 2013 at 3:47 PM, Florian Lindner <[email protected]>wrote: > Am Dienstag, 29.
