Specify resource and network settings for provisioning machines from this vRealize Automation reservation.

You can select a FlexClone datastore in your reservation if you have a vSphere environment and storage devices that use Net App FlexClone technology. SDRS is not supported for FlexClone storage devices.

To provision successfully, the reservation must have sufficient available storage. The reservation's storage availability depends on:

  • How much storage is available on the datastore/cluster.

  • How much of that storage is reserved for that datastore/cluster.

  • How much of that storage is already allocated in vRealize Automation

For example, even if the vCenter Server has storage available for the datastore/cluster, if sufficient storage is not reserved in the reservation then provisioning fails with a "No reservation is available to allocate..." error. The allocated storage on a reservation depends on the number of VMs (regardless of their state) on that specific reservation. See the VMware Knowledge Base article Machine XXX: No reservation is available to allocate within the group XXX. Total XX GB of storage was requested (2151030) at http://kb.vmware.com/kb/2151030 for more information.


  1. Click the Resouces tab.
  2. Select a compute resource on which to provision machines from the Compute resource drop-down menu.

    Only templates located on the cluster you select are available for cloning with this reservation.

    During provisioning, machines are placed on a host that is connected to the local storage. If the reservation uses local storage, all the machines that are provisioned by the reservation are created on the host that contains that local storage. However, if you use the VirtualMachine.Admin.ForceHost custom property, which forces a machine to be provisioned to a different host, provisioning fails. Provisioning also fails if the template from which the machine is cloned is on local storage, but attached to a machine on a different cluster. In this case, provisioning fails because it cannot access the template.

  3. (Optional) Enter a number in the Machine quota text box to set the maximum number of machines that can be provisioned on this reservation.

    Only machines that are powered on are counted towards the quota. Leave blank to make the reservation unlimited.

  4. Specify the amount of memory, in GB, to be allocated to this reservation from the Memory table.

    The overall memory value for the reservation is derived from your compute resource selection.

  5. Select one or more listed storage paths.

    The available storage path options are derived from your compute resource selection.

    For integrations that use Storage Distributed Resource Scheduler (SDRS) storage, you can select a storage cluster to allow SDRS to automatically handle storage placement and load balancing for machines provisioned from this reservation. The SDRS automation mode must be set to Automatic. Otherwise, select a datastore within the cluster for standalone datastore behavior. SDRS is not supported for FlexClone storage devices.

    You can select either individual disks in the cluster or a storage cluster, but not both. If you select a storage cluster, SDRS controls storage placement and load balancing for machines that are provisioned from this reservation.

  6. If available for the compute resource, select a resource pool in the Resource Pool drop-down menu.
  7. Click the Network tab.
  8. Configure a network path for machines provisioned by using this reservation.
    1. (Optional) If the option is available, select a storage endpoint from the Endpoint drop-down menu.

      The FlexClone option is visible in the endpoint column if a NetApp ONTAP endpoint exists and if the host is virtual. If there is a NetApp ONTAP endpoint, the reservation page displays the endpoint assigned to the storage path. When you add, update, or delete an endpoint for a storage path, the change is visible in all the applicable reservations.

      When you add, update, or delete an endpoint for a storage path, the change is visible in the reservation page.

    2. Select a network paths for machines provisioned by this reservation from the Network Paths list.
    3. (Optional) Select a listed network profile from the Network Profile drop-down menu.

      This option requires that one or more network profiles exists.

    You can select more than one network path on a reservation, but only one network is used when provisioning a machine.


You can save the reservation now by clicking Save. Or you can add custom properties to further control reservation specifications. You can also configure email alerts to send notifications when resources allocated to this reservation become low.
