Subject Re: Problem in adding Ceph RBD as primary storage for CloudStack 4.1.0
Date Fri, 12 Jul 2013 06:56:35 GMT
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.

See here: https://cwiki.apache.org/confluence/x/FgPMAQ
