Indeed, cloudstack will go through the allocation to startup the system VMs too. So that process is failing to recognize the volume (.qcow2) present on your NFS storage.
Can you check if your cloudstack agent service is running with the KVM host? And it should've created the user cloud. $id cloud to check if there is a user. Did you see what's happening in the agent logs? These are under /var/log/cloud/ on your host when the systemVMs are coming up. If the logs are not showing any useful information you can turn on debug level for more verbosity.
