CPU/Memory Hot-Add Parameters failing to apply from Aria Automation cloud template to vSphere

Products

• VMware Aria Suite

Issue/Introduction

When attempting to enable the CPU/Memory Hot-Add feature in vSphere through Aria Automation cloud template, the configuration may not be successfully applied.

Environment

Aria Automation 8.x

Cause

CPU/Memory Hot-Add is a VMX-level setting. OOB(Out-of-Box) Aria Automation Cloud Template canvas can't modify any other parameters apart from OS configurations.

Resolution

To enable the CPU/Memory Hot-add feature during VM deployment, follow these steps:

Create a Custom Workflow: Utilize Aria Automation extensibility features to create a custom workflow that modifies the VMX file during deployment. This workflow can configure the necessary properties to pass the Hot-add feature to vCenter.

For more details on how to configure such workflows, refer to the following documentation:
Extensibility in Cloud Assembly - Creating an Extensibility Subscription

This solution leverages the Aria Automation extensibility framework to modify VM hardware settings at the VMX level.
