vRA-Lab-12-Create Reservations

Before members of a business group can request machines, fabric administrators must allocate resources to them by creating a reservation.

Each business group must have at least one reservation for its members to provision machines of that type.


Log in to the vRealize Automation console as a fabric administrator. In my case, I have created one already in my Active Directory with name “vmexpo-fadmin@vcaplab.local” and gave permission to configure fabric group during “create Fabric Group” Configuration. Enter the “credentials” and click “Login”



Once you login. At left side, you may choose the “My Goal” Configuration Wizard or go to “infrastructure” tab->Reservations-> Reservations > Click “New Reservations-> Virtual-> vSphere (vCenter)”.


1-Specify Reservation Information

Each reservation is configured for a specific business group to grant them access to request machines on a specified compute resource.

1-Select a compute resource “RG-Cluster (vc01)” on which to provision machines from the Compute resource drop-down menu.

NOTE: Only templates located on the cluster you selected are available for cloning with this reservation.

2-Enter the reservation name “RG-Cluster-Res-1” and Select a tenant “vmexpo” from the Tenant drop-down menu..

3-Select a business group “VMExpo-IT-Prod” from the Business group drop-down menu.

NOTE: Only users in this business group can provision machines by using this reservation.

 4- Select a reservation policy (Optional) from the Reservation policy drop-down menu. I don’t created one. I will come back and configure it later.

5- Type a number in the Machine quota (optional) text box to set the maximum number of machines that can be provisioned on this reservation.

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

6- Type a number in the Priority “1” in text box to set the priority for the reservation.

NOTE: The priority is used when a business group has more than one reservation. A reservation with priority 1 is used for provisioning over a reservation with priority 2.

7-Check the “Enable this reservation” to make it active and Add any custom properties (Optional).


2-Specify Memory, Storage, and Network Resources

Configure the memory, storage, and network paths available to machines provisioned through this reservation.

NOTE: 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.

1-Click the “Resources tab”. Specify the amount of memory “10”, in GB, to be allocated to this reservation from the Memory table.

2-Configure a storage path in the Storage table. Select a storage path “NFS-Datastore” from the Storage Path column and Type “10” value in This Reservation Reserved to specify how much storage to allocate to this reservation.

3-Specify the Priority “1” for the storage path.

4-Choose the “Resource pool” from the Resource Pool drop down.

NOTE: The priority is used for multiple storage paths. A storage path with priority 0 is used before a path with priority 1. Repeat this step to configure clusters and datastores as needed.


Next click the “Network” tab to configure a network path for machines provisioned by using this reservation.

1-Select a network path for machines provisioned “PG-VM-External” on this reservation from the Network table. I already created this in my vCAC network baseline section.

2-Select a network profile (optional) from the Network Profile drop-down menu. I leave it blank because I did not configure any network profile yet. I will come back here later for configuration.


Next go to “Alerts” tab.

1-Set capacity alerts to “On”. Use the sliders to set thresholds for resource allocation according to your needs, I leave it as default.

2-Type one/more user email addresses “vmexpo-admins@vmexpo.local” or group names to receive alert notifications in the Recipients text box.

3-Select “Send alerts to group manager” to include group managers in the email alerts and Choose a reminder frequency “1” (days).

4-Click “OK”.


Verify your first created reservation as shown below.


Similarly create other reservations, if you want to.

Little TIP:

Some time you need to change/add the configure at Hypervisors which are using vCAC for Compute resources, such as “vSphere” and you will notice your changes are not reflected to the vCAC interface. It is because vCAC pull the inventory data by default after 1 day. But it is possible to run it manually or change the interval as you required.

To run the data collection manually go to “Infrastructure-> Compute Resources -> Select your Computer resources and choose “Data Collection”


In data Collection. Go to “Inventory” Section -> you may change the inventory pulling “interval frequency” or click “request now” to run it manually. Once you Click “Request Now”.

Check the “Last Complete status” of inventory collection process to verify when its last time ran. If latest status is not reflecting then you may click “Refresh” button from bottom. 

One done -> Click “OK”
