I *just* ran into a problem today triggered by some code moving around in nova and common. I had to set my driver to "nova.openstack.common.notifier.rabbit_notifier" (in both files).

I didn't see any errors from that until I tried to launch an instance, so it doesn't seem to prevent any of the nova services from starting up.

I'm having the same problem.  I'm running against nova trunk and I have rabbit notifier enabled.

Dear Doug,
    I`m use Qpid instead of Rabbit .
    Did it cause the error ?
    In addition,my nova.conf,mongodb.conf and ceilometer-collector.conf are here:
    http://pastebin.com/sW5d8eRv
    http://pastebin.com/D5GMkLsb
    http://pastebin.com/u5vH22Lh
    Were there some errors in my config files?

    Waiting your reply. Thanks.

Dear all,

    As the project named ceilometer appeared,I paid close attention to it.
    According to the docs of ceilometer,I deploied it in openstack exsse environment.
    While,I cannot start the ceilometer collector and agent.

    The follows are my operations.

    1.Install openstack nova ,mongodb and ceilometer.
    2.configurate nova ,mongodb and ceilometer

    The /etc/nova/nova.conf file is here:
    http://pastebin.com/sW5d8eRv

    Here is the /etc/ceilometer-collector.conf file is here:
    http://pastebin.com/u5vH22Lh

    And the /etc/mongodb.conf is here:
    http://pastebin.com/D5GMkLsb

    3.Start openstack nova ,mongodb

    4.Then I start the ceilometer-collector
    /usr/bin/ceilometer-collector start
    While,some errors occurred:

    If anyone can help me ? Waiting your reply. Thanks !

It looks like we have a problem with the way we are loading nova's settings under Essex. I know some of the flags and cfg code was moved around and changed between Essex and Folsom as part of it moved into openstack-common. Julien, you're more familiar with Essex than I am, do you have any ideas about this problem?

I think I left out a configuration step in the instructions at http://ceilometer.readthedocs.org/en/latest/install.html.

Did you configure your system to use the Rabbit notifier?

Doug
