Hello folks I am following the opennebula 6.2 kvm [installation guide](https://docs.opennebula.io/6.2/open_cluster_deployment/kvm_node/kvm_node_installation.htm) on Debian Buster and am running into some issues. The front-end nodes have a full `oneadmin` account with ssh credentials/keys. The installation of the kvm nodes using `apt-get -y install opennebula-node-kvm` also give a `oneadmin` account but the .ssh directory is not created, no keys in `/var/lib/one/.ssh` It seems the installation guide is incomplete, since `oneadmin@kvmnode~:# ssh front-end` does not have a key, so a password is required. How do i go about that? Thank you fd0 ---

Hi, You must be missed the installation guide. Details about configuring Passwordless SSH can be followed in this link [configure passwordless SSH](https://docs.opennebula.io/6.2/open_cluster_deployment/kvm_node/kvm_node_installation.html#step-4-configure-passwordless-ssh). Also take a look at [how to populate SSH keys](https://docs.opennebula.io/6.2/open_cluster_deployment/kvm_node/kvm_node_installation.html#a-populate-host-ssh-keys) Please make sure about this can established: - from Front-end to Front-end, - from Front-end to hypervisor Node, - from Front-end to hypervisor Node with another connection within to another Node (for migration operations), - from Front-end to hypervisor Node with another connection within back to Front-end (for data copy back). Regards, H Suryapambagya ---

Thank you for your response @Harry_Suryapambagya I have done things differently, result is the same though. fd0 ---

For the interested I handled things this way: - KVM node installation comes without ssh-key for user _ **oneadmin** _. On first node i created ssh credentials for _ **oneadmin** _ - All front-end nodes come with different ssh credentials for _ **oneadmin** _ - Added public key of _oneadmin_ on first front-end node to first KVM node’s _authorized\_keys_ file - Added public key of _oneadmin_ on first KVM node to first front-end node’s _authorized\_keys_ file - copied .ssh of first KVM node to all othe KVM nodes - copied .ssh of first front-end to all other front-end nodes - tested works as intended ---
