[one-users] Live migration fail

[Campbell, Bill]

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.

​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. 



Regards & Best Wishes,
