## Change
You can determine the number of running VMs and reservations that match the properties of a future reservation request. By subtracting this number from the total count specified in a future reservation request, you can determine the number of reserved VMs that an existing future reservation provisions at its start time. For more information, see [Determine the number of provisioned VMs](https://cloud.google.com/compute/docs/instances/view-future-reservations#determine-provisioned-vms).
## Change
You can create a future reservation request by reusing the properties of an existing VM. This lets you consume the auto-created reservations for the future reservation by creating VMs with properties that exactly match the reference VM's properties. For more information, see the following:

* [Create shared future reservation requests](https://cloud.google.com/compute/docs/instances/create-shared-future-reservations)
