Hi Linstor + Cloudstack Appliance/ stack is good and is generally designed to be used as Aggregated setup, here you would see maximum benefits plus as Bryan mentioned, it uses very Low CPU at the background which leaves more CPU for supervisors to use.
Upgrading this setup would have to be done separately, else you might consider contacting Linbit Support for more details.
