Hi, after the havana to icehouse upgrade VNC is not working. Here what I found in consoleauth.log :

[root@Openstack-controller nova(keystone_admin)]# cat consoleauth.log | grep ERROR
2015-05-28 16:43:55.381 25302 ERROR oslo.messaging.rpc.dispatcher [-] Exception during message handling: Endpoint does not support RPC version 1.2
2015-05-28 16:43:55.400 25302 ERROR oslo.messaging._drivers.common [-] Returning exception Endpoint does not support RPC version 1.2 to caller
2015-05-28 16:43:55.400 25302 ERROR oslo.messaging._drivers.common [-] ['Traceback (most recent call last):\n', '  File "/usr/lib/python2.6/site-packages/oslo/messaging/rpc/dispatcher.py", line 133, in _dispatch_and_reply\n    incoming.message))\n', '  File "/usr/lib/python2.6/site-packages/oslo/messaging/rpc/dispatcher.py", line 185, in _dispatch\n    raise UnsupportedVersion(version)\n', 'UnsupportedVersion: Endpoint does not support RPC version 1.2\n']

Here my controller nova.conf:

novncproxy_host=0.0.0.0
novncproxy_port=6080
novncproxy_base_url=http://CONTROLLER_IP:6080/vnc_auto.html
vncserver_listen=0.0.0.0
vncserver_proxyclient_address=CONTROLLER_IP

Here my compute nova.conf:

novncproxy_base_url=http://CONTROLLER_IP:6080/vnc_auto.html
vncserver_listen=COMPUTE_IP
vncserver_proxyclient_address=COMPUTE_IP
vnc_enabled=True

UPDATE

It is important to know that during the upgrade i passed from qpid to rabbitmq; I changed all related info on config files. Could it be related to this change?

Thanks

UPDATE 2

This is my endpoint list. Do you think there is something missing/wrong?
