Table Of Contents
The reservation for which a machine is provisioned must satisfy the following criteria:
n
The reservation must be of the same platform type as the blueprint from which the machine was
requested.
n
The reservation must be enabled.
n
The reservation must have capacity remaining in its machine quota or have an unlimited quota.
The allocated machine quota includes only machines that are powered on. For example, if a
reservation has a quota of 50, and 40 machines have been provisioned but only 20 of them are
powered on, the reservation’s quota is 40 percent allocated, not 80 percent.
n
The reservation must have the security groups specified in the machine request.
n
The reservation must be associated with a region that has the machine image specified in the
blueprint.
n
The reservation must have sufficient unallocated memory and storage resources to provision the
machine.
In a Pay As You Go reservation, resources can be unlimited.
n
For Amazon machines, the request specifies an availability zone and whether the machine is to be
provisioned a subnet in a Virtual Private Cloud (VPC) or a in a non-VPC location. The reservation
must match the network type (VPC or non-VPC).
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.
