Oracle VM: Error 1011

When you add a server pool you can see the following error.


OVM 1011 OVM Manager communication with [server's IP] for operation pre-check root for server pool failed: 
,'ofs2.local.cluster2'] >


=> you could see this if there is no shared storage in OVM servers. If you don't have any shared storage like SAN, you can use NFS instead. Import NFS server into OVM servsers. 


1) Add the NFS to the repository using repos.py script.   
/opt/ovs-agent-2.3/utils/repos.py -n source


2) Register the NFS as the primary repository.
/opt/ovs-agent-2.3/utils/repos.py -r uuid


3) Delete original local disk
/opt/ovs-agent-2.3/utils/repos.py -d uuid


# list
/opt/ovs-agent-2.3/utils/repos.py -l
# add new one   
/opt/ovs-agent-2.3/utils/repos.py -n source
# delete
/opt/ovs-agent-2.3/utils/repos.py -d uuid
# register as a primary.
/opt/ovs-agent-2.3/utils/repos.py -r uuid
