Configure ESX resource pools

The ESX server has a default resource pool called Resources that defines normal resources for a virtual machine.

Before you begin

Role required: admin

About this task

Resource levels are dynamically generated from shares of the total resources allocated to virtual machines on the ESX server. For details about how these resources are calculated, review the VMware Knowledge Base ServiceNow Discovery finds this default resource pool and adds a record to the ESX Resource Pools module automatically. If Discovery is not running on the ServiceNow instance, create a record for the Resources pool. Ensure that the Owner field is correct and leave the resource fields blank. If a provisioner selects the Resources pool when provisioning a virtual server, the ESX server will create a virtual machine for use under a normal load.


  1. Navigate to VMware Cloud > Configuration > ESX Resource Pools.
  2. Click New in the list.
  3. Create a new record for each resource pool in the ESX server, ensuring that the Name and Owner fields are correct.
  4. Select the CPU expandable and Memory expandable check boxes to allow for expansion of the CPU and memory limits when needed, if those resources are available on the ESX server.

    When granted, these extra resources can be revoked if needed to provision other virtual machines. The additional fields on the form are for display purposes only.

  5. Click Submit.
