             Summary: Unable to add KVM host 
                 Key: CLOUDSTACK-1648
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-1648
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
          Components: KVM
    Affects Versions: 4.0.0, 4.1.0
            Reporter: Harikrishna Patnala


Trying to add a kvm host in basic zone.
Failed after time out occured.
Checked the agent log in KVM host, seems like conflict occurring with storage 
pool.
Tried removing the storage pool and re-installing the cloudstack agent.
Even then failing on the same error.
Here is the cloudstack agent log in kvm:
