Hi Mike, I have setup ~3 cloudstack clusters on KVM and have never needed to manually run the cloud(stack)-setup-agent, as this is preformed by the management server on first connect. I setup a long password for root on each of my hypervisors which I use for the cloudstack management when entering the host details into cloudstack interface.
