Not related to the topic, but Ceilometer doesn't have this issue
anymore. Since Nova writes the uuid of the instance inside the libvirt
instance metadata. We just associate libvirt metrics to the instance
uuid. And then correlate them with the full metdata we receive via
notification. We don't poll nova at all anymore.
