Once created, you can edit, delete, add, or remove VMs from the resource pools:

• Edit a resource pool: From vSphere Client, right-click the object and select Edit Resource Settings. Change the CPU and RAM settings then click OK to confirm.
• Delete a resource pool: From vSphere Client, right-click the resource pool and select Delete. Click OK to confirm deletion. Deleting a resource pool doesn't delete the VM it contains.
• Adding a VM: A VM can be added to a resource pool during the creation process, using the Migrate... functionality or using the drag and drop feature.
• Removing a VM: From a resource pool, right-click the VM to remove, and select the option Migrate... to move it to another resource pool. Use the drag and drop feature to move a VM off the resource pool instead.
