multi-host unable to connect.

asked 2013-01-21 11:16:33 -0600

I have one cloud-controller and one compute-node.

Cloud-controller ip address : 192.168.4.75 compute-node 1 : 192.168.4.72

Normally cloud-controller and compute-node can connect but now it can't connect.

When i use command "nova-manage service list" in cloud-controller ;

root@devstack:/# nova-manage service list 2012-08-20 17:54:00 DEBUG nova.utils [req-331af51e-38ba-4bc5-9007-d8f38745a062 None None] backend <module 'nova.db.sqlalchemy.api'="" from="" '="" usr="" lib="" python2.7="" dist-packages="" nova="" db="" sqlalchemy="" api.pyc'=""> from (pid=5660) __get_backend /usr/lib/python2.7/dist-packages/nova/utils.py:658 Binary Host Zone Status State Updated_At nova-compute devstack nova enabled :-) 2012-08-20 10:53:54 nova-cert devstack nova enabled :-) 2012-08-20 10:53:59 nova-consoleauth devstack nova enabled :-) 2012-08-20 10:53:58 nova-console devstack nova enabled :-) 2012-08-20 10:53:59 nova-scheduler devstack nova enabled :-) 2012-08-20 10:53:56 nova-volume devstack nova enabled :-) 2012-08-20 10:53:52 nova-network devstack nova enabled :-) 2012-08-20 10:53:56 nova-compute openstackagent nova enabled XXX 2013-01-21 11:04:49 nova-network openstackagent nova enabled XXX 2013-01-21 11:04:52

When you say can't connect can you explain further?

Can you also post logs, and we can have a look for errors?
