Amier,
Yes, each KVM node will need to be able to authenticate with each other
directly, so you'll need to do one of the following:
* Create a key on each node and ssh-copy-id to each kvm node
* Use the same key/pair that is used to communicate from OpenNebula to the
nodes between nodes (i.e. copy the /var/lib/one/.ssh directory to each node).
We use the second one and it works well, but either should work.

the VM is still RUNNING (will poll VM).
Do I need to do ssh-key to each other for each worker node? I have no issue to
deploy vm from my frontend to each of the worker node.
I also have make it all the node into the cluster with same datastore. but
still doesn work. same error log.
Thanks you.
