I could understand the reasoning and it could be done, however you lose a lot of what makes Cloudstack the orchestration software it is. Here are a few disadvantages to doing it this way:
1. You could not manage the ACS control node through ACS which means you couldn’t migrate it add disks to it, get to the console, etc via ACS. You would have to do it all via the hypervisor management. 2. Since ACS doesn't know about it, it can't report on the hyper-visor usage or storage usage which means your usage graphs and records will always be "off" a little. 3. Simple tasks such as putting hosts in maintenance and hypervisor upgrades now become more tedious since you have a guest on the hypervisor that ACS doesn't know about to work around. I could write a few more but as you can see, it really is not a good idea. I do the same as the other responder. I run my ACS management nodes on another cluster that is not part of the ACS cluster. This allows me to let ACS fully control those hypervisors.
