You can create a project scenario that uses an existing virtual machine profile as a model to simulate the resource requirements if you add one or more virtual machines to a host or cluster.

To configure the settings in a project scenario that adds virtual machines to your planned capacity, you can populate the resource values for the planned virtual machine from an existing profile, or you can copy the values from an existing virtual machine.

To calculate the capacity metrics values for the virtual machine, vRealize Operations Manager partitions the capacity for CPU, memory, and disk dimensions, according to the profile that you select.

For information about CPU and memory maximums, see the VMware vSphere documentation.


In the vRealize Operations Manager navigation tree, click the host or cluster where the planned virtual machine would reside, and click Projects.


Click Add New Project.


In the Projects workspace, enter a name and description for the project.


For the Status, select Planned - no badges affected.


In the workspace, click Scenarios.


Under Add Demand, drag the scenario named add Virtual Machine to the Scenarios pane.


In the Configuration pane, enter the general parameters for the project scenario.


Select the date and time to implement the project scenario.


Click Populate metrics from, select an existing profile or an existing virtual machine, and click OK.



Copy metric values from a pre-defined profile.

From the Profile drop-down menu, select an existing profile to populate the metrics values for the planned virtual machine.

Copy metric values from an existing object.

From the Existing Virtual Machine drop-down menu, select a virtual machine to populate the metrics values for the planned virtual machine. The list displays the virtual machines that reside on the selected object.


(Optional) To duplicate virtual machines, increase the virtual machine count.


To see the effect of the planned virtual machines in the visualization chart, click Save project and continue editing.

With the Capacity Container set to Most Constrained, the visualization chart might indicate that you would have a CPU shortfall when you implement the project scenario, because the CPU allocation would be greater than the available capacity. In this case, you would need to add CPU capacity before you implement the project scenario.


When you are satisfied with the capacity forecast based on your settings, click Save to add the scenario to the project.


In the Projects view, click your project in the list and drag it to the pane just above the project list.

vRealize Operations Manager applies your project and scenario to the visualization chart. The capacity forecasted in the project appears as a gray line in the chart.

In the visualization chart, evaluate the current available capacity with the actual capacity required if you make the changes defined in your project. Then, determine whether to commit the project so that it reserves the capacity required for the new virtual machines.
