Open Stack

Thank you for clarifying it.

But in my SLES environment, following the suse install guide:

# openstack-config --set /etc/nova/nova.conf DEFAULT
notification_driver nova.openstack.common.notifier.rpc_notifier
# openstack-config --set /etc/nova/nova.conf DEFAULT
notification_driver ceilometer.compute.nova_driver

the nova.openstack.common.notifier.rpc_notifier is overwrite by
ceilometer.compute.nova_notifier, but ceilometer meter-list still can
show instance and instance.flavor. I'm confused.
