Hi Sven,

Thanks for your input, see response below.

Good point. Cluster level would be similar in implementation to DC level
(and might be as useful), the point being that both are relatively
complex and out of the scope of this current feature. I'll update the
feature page to mention the cluster level as well.

It might be useful to integrate with Ceilometer, oVirt will definitely
try to leverage OpenStack wherever possible. Specifically for the
billing use case (which relates more to VM QoS than to host QoS), maybe
someone who knows more about SLA than me would care to comment.
