<br>
I'm looking for the most convenient setting to be able to
passwordlessly ssh between the VM's created by OpenNebula.
I've noticed that the settings which provide passwordless
ssh from the Front-end (or Hosts) into VM's do not deal
with this, the system is still asking for a password if I
want to ssh from VM into VM. So, did I do something wrong,
and in theory, the exact same steps would need to be
followed in case of VM's too, or is there some trick?<br>

To enable password less communication between VMs you need top
create a SSH key for a user (root?) that will be in all you VMs.<br>
You should also disable in ssh_config the know_hosts feature (or
redirect it to /dev/null).<br>
<br>
For SSH there are multiple means. You create a VM with a SSH key
inside, the drawback is the SSH key is the same for all VMs e.g. all
users, this is not secure but for test only it would fit.<br>
At boot time you load the ssh key for a file set in CONTEXT
template, with a key dedicated per user. Or, still at boot time, you
trigger a server (you made) to get a SSH key from the VM ip.<br>
