7.2

Reservation policies are a way to guarantee that the selected reservation satisfies any additional
requirements for provisioning machines from a specific blueprint. For example, you can use
reservation policies to limit provisioning to compute resources with a specific template for cloning.
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
If the blueprint or request specifies a storage reservation policy, the storage path must belong to that
storage reservation policy.
If the value of the custom property VirtualMachine.DiskN.StorageReservationPolicyMode is NotExact
and there is no storage path with sufficient capacity within the storage reservation policy, then
provisioning can proceed with a storage path outside the specified storage reservation policy. The
default value of VirtualMachine.DiskN.StorageReservationPolicyMode is Exact.
n
A storage path with a lower priority value is selected before a storage path with a higher priority value.
n
If multiple storage paths have the same priority, machines are distributed among storage paths in
round-robin fashion.
Creating a vSphere Reservation for NSX Network and Security Virtualization
You can create a vSphere reservation to assign external networks and routed gateways to network
profiles for networks, specify the transport zone, and assign security groups to machine components.
If you have configured VMware NSX, and installed the NSX plug-in for vRealize Automation, you can
specify NSX transport zone, Edge and routed gateway reservation policy, and app isolation settings when
you create or edit a blueprint. These settings are available on the NSX Settings tab on the New
Blueprint and Blueprint Properties pages.
The network and security component settings that you add to the design canvas are derived from your
NSX configuration and require that you have installed the NSX plug-in and run data collection for the NSX
inventory for vSphere clusters. Network and security components are specific to NSX and are available
for use with vSphere machine components only. For information about configuring NSX, see NSX
Administration Guide.
