n
For vCloud Air or vCloud Director, if the request specifies an allocation model, the virtual datacenter
associated with the reservation must have the same allocation model.
n
For vCloud Director or vCloud Air, the specified organization must be enabled.
n
Any blueprint templates must be available on the reservation. If the reservation policy maps to more
than one resources, the templates should be public.
n
If the cloud provider supports network selection and the blueprint has specific network settings, the
reservation must have the same networks.
If the blueprint or reservation specifies a network profile for static IP address assignment, an IP
address must be available to assign to the new machine.
n
If the request specifies an allocation model, the allocation model in the reservation must match the
allocation model in the request.
n
If the blueprint specifies a reservation policy, the reservation must belong to that reservation policy.
Reservation policies are a way to guarantee that the selected reservation satisfies any additional
requirements for provisioning machines from a specific blueprint. For example, if a blueprint uses a
specific machine image, you can use reservation policies to limit provisioning to reservations
associated with the regions that have the required image.
If no reservation is available that meets all of the selection criteria, provisioning fails.
If multiple reservations meet all of the criteria, the reservation from which to provision a requested
machine is determined by the following logic:
n
A reservation with a lower priority value is selected before a reservation with a higher priority value.
n
If multiple reservations have the same priority, the reservation with the lowest percentage of its
machine quota allocated is selected.
n
If multiple reservations have the same priority and quota usage, machines are distributed among
reservations in round-robin fashion.
Note While round-robin selection of network profiles is not supported, round-robin selection of
networks (if any) is supported, which can be associated with different network profiles.
If multiple storage paths are available on a reservation with sufficient capacity to provision the machine
volumes, storage paths are selected according to the following logic.
n
A storage path with a lower priority value is selected before a storage path with a higher priority value.
n
If the blueprint or request specifies a storage reservation policy, the storage path must belong to that
storage reservation policy.
If the custom property VirtualMachine.DiskN.StorageReservationPolicyMode is set to Not
Exact, and no storage path with sufficient capacity is available in the storage reservation policy, then
provisioning proceeds with a storage path outside the specified storage reservation policy. The
default value of VirtualMachine.DiskN.StorageReservationPolicyMode is Exact.
