If the value of the custom property VRM.Datacenter.Policy is Exact and there is no reservation for a
compute resource associated with that location that satisfies all the other criteria, then provisioning
fails.
If the value of VRM.Datacenter.Policy is NotExact and there is no reservation for a compute resource
associated with that location that satisfies all the other criteria, provisioning can proceed on another
reservation regardless of location. This option is the default.
n
If the blueprint or request specifies the custom property VirtualMachine.Host.TpmEnabled, trusted
hardware must be installed on the compute resource for the reservation.
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, 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.
