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 that blueprint to a subset of available reservations.

You can use a reservation policy to collect resources into groups for different service levels, or to make a specific type of resource easily available for a particular purpose. When a user requests a machine, it can be provisioned on any reservation of the appropriate type that has sufficient capacity for the machine. The following scenarios provide a few examples of possible uses for reservation policies:

  • To ensure that provisioned machines are placed on reservations with specific devices that support NetApp FlexClone.

  • To restrict provisioning of cloud machines to a specific region containing a machine image that is required for a specific blueprint.

  • As an additional means of using a Pay As You Go allocation model for machine types that support that capability.

Note:

vCloud Air endpoints and vCloud Director endpoints do not support network profiles in a machine deployment.

You can add multiple reservations to a reservation policy, but a reservation can belong to only one policy. You can assign a single reservation policy to more than one blueprint. A blueprint can have only one reservation policy.

A reservation policy can include reservations of different types, but only reservations that match the blueprint type are considered when selecting a reservation for a particular request.

Reservation policies provide an optional means of controlling how reservation requests are processed. You can apply a reservation policy to a blueprint to restrict the machines provisioned from that blueprint to a subset of available reservations.
