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.
n
If multiple storage paths have the same priority, machines are distributed among storage paths by
using round-robin scheduling.
Create an Amazon EC2 Reservation
You must allocate resources to machines by creating a reservation before members of a business group
can request machine provisioning.
You can work with Amazon reservations for Amazon Virtual Private Cloud or Amazon non-VPC.
Amazon Web Services users can create a Amazon Virtual Private Cloud to design a virtual network
topology according to your specifications. If you plan to use Amazon VPC, you must assign an
Amazon VPC to a vRealize Automation reservation. See .
When you create an Amazon reservation or configure a machine component in the blueprint, you can
choose from the list of security groups that are available to the specified Amazon region. Security groups
are imported during data collection.
Note After you create a reservation, you cannot change the business group or compute resource
associations.
For information about creating an Amazon VPC by using the AWS Management Console, see
Amazon Web Services documentation.
