Aria Automation VM resize failed with error "The operation Resize failed. Error from vCenter: Invalid virtual machine configuration."


Issue/Introduction

Symptoms:

  • trying to increase memory to a much larger amount, for an existing running VM is failing with "The operation Resize failed. Error from vCenter: Invalid virtual machine configuration."
  • increasing the memory to a smaller amount is working fine
  • increasing the memory on a running VM, step by step is also failing once hitting a multiple of 16 times of the original RAM
  • attempting to increase the memory on the running VM directly in vCenter is not allowing more then multiple of 16 times of the original RAM
  • the VM task in vCenter does not provide any detailed information to why the task has failed

Environment

  • Aria Automation 8.x
  • vSphere 7.x
  • vSphere 8.x

Cause

The maximum amount of hot add memory is x16 the initial amount of memory provisioned for the VM.

For example, if a VM has 4 GB of RAM, this amount can be increased up to 64 GB.

Resolution

To increase the memory further then 16 times a VM reboot is required, please select the reboot tick box when requesting the VM resize from Aria Automation.
