Troubleshoot your cloudpipe instance
A periodic task disassociates the fixed ip address for the cloudpipe instance. Into
/var/log/nova/nova-network.log, the following line should appear :Running periodic task VlanManager._disassociate_stale_fixed_ips from (pid=21578) periodic_tasks /usr/lib/python2.7/dist-packages/nova/manager.py:152
Once the job has been run,
$nova cloudpipe-listshould not return anything ; but if the cloudpipe instance is respawned too quickly; the following error could be encountered :ERROR nova.rpc.amqp Returning exception Fixed IP address 192.168.22.34 is already in use.
In order to resolve that issue, log into the mysql server and update the ip address status :
(mysql) use nova;
(mysql) SELECT * FROM fixed_ips WHERE address='192.168.22.34';

Nova stores cloudpipe keys into
/var/lib/nova/keys.Certificates are stored into
/var/lib/nova/CA.Credentials are stored into
/var/lib/nova/CA/projects/Automate the cloudpipe image installation
You can automate the image creation by download that script and running it from inside the instance : Get the script from Github
