This only applies to our Cloud VM plans.
If you are seeing anything other than €0 in the Price per hour then that means you have something enabled on the VM that is billable at an extra cost to the basic price for the plan you are on.
That could be that you have a Windows template selected, or have an extra IP address enabled for example.
Don't worry though, you won't be charged €1 an hour for those services! The billing for all services in relation to the Cloud VM plans is handled by our external billing system that you can log in to at http://cp.blacknight.com. So you can essentially ignore any figures in Onapp.
