So usage metrics on CPU / RAM / DISK / Network (over provisioned or not is another story) There is an aspect on actual usage versus provisioned usage. {vm provisioned 10 GB of RAM bus os+app uses just 5 GB of them etc) But let's keep it simple. Should we have the usage reference then a GUI that the can define the cost plans, would be ideal. A way to query if possible that database, would ease existing ERPs and invoicing software to produce / send invoices. This is for mostly post paid use cases. For prepaid situations, there must be some regular accounting that will stop the service through our current API. It sounds a bit scaring to actually shutdown the provisioned vm. So at least on first step stop the networking .... I guess that the base is to create a separate database that will keep the consumed metrics, so that customers could actually use it to enforce some business logic. (as explained above). Should there be a minimal gui that could a small hoster create his owns plans and perhaps issue some "invoice" would be ideal. Since there are a number of open source billing systems out there, perhaps the integration is not that complicated. A second thought would be to extend the data ware house gui to create the "invoice" outputs as most of the usage info is there. I know that ovirt is supposed to be a virtualization solution and not a full monty billing system. Thanks for reading so far.
