Create a vSphere, KVM (RHEV), or SCVMM create, clone, or FlexClone blueprint that uses a storage
reservation policy. See Choosing a Storage Scenario.
Procedure
1 Select Infrastructure > Blueprints > Blueprints.
2 Point to the blueprint for which you want to allow alternative datastores and click Edit.
3 Click the Properties tab.
4 Click New Property.
5 Type VirtualMachine.DiskN.StorageReservationPolicyMode in the Name text box.
N is the index (starting at 0) of the volume.
6 Type the Not Exact in the Value text box.
Exact restricts provisioning to the datastores in the storage reservation policy. This is the default.
7 (Optional) Select the Encrypted check box to encrypt the custom property in the database.
8 (Optional) Select the Prompt user check box to require the user to provide a value when they
request a machine.
If you choose to prompt users for a value, any value you provide for the custom property is presented
to them as the default. If you do not provide a default, users cannot continue with the machine
request until they provide a value for the custom property.

Reservation Policies
When a user requests a machine, it can be provisioned on any reservation of the appropriate type that
has sufficient capacity for the machine. You can apply a reservation policy to a blueprint to restrict the
machines provisioned from a that blueprint to a subset of available reservations.
Reservation policies provide an optional and helpful means of controlling how reservation requests are
processed. A reservation policy is often used to collect resources into groups for different service levels,
or to make a specific type of resource easily available for a particular purpose. The following scenarios
provide a few examples of possible uses for reservation policies:
n
To ensure that machines provisioned from a virtual blueprint are placed on reservations with storage
devices that support NetApp FlexClone
n
To restrict provisioning of cloud machines to a specific region containing a machine image that is
required for a specific blueprint
n
To restrict provisioning of Cisco UCS physical machines to reservations on endpoints on which the
selected service profile template and boot policy are available
n
As an additional means of using a Pay As You Go allocation model for vApps
