ON installed on a virtual machine.
Task: connect a remote node with installed KVM to ON.
Unfortunately, I only found how to do this here https://www.alibabacloud.com/blog/how-to-install-and-configure-opennebula-on-ubuntu-18-04_595917 section “Configure Key-base SSH Authentication on OpenNebula Front-end”
Versions of the related components and OS (frontend, hypervisors, VMs):
Node1 (192.168.10.171): CentOS 8.3, OpenNebula 6
Node2 (192.168.10.169): CentOS 8.3, KVM
Steps to reproduce:
On Node1 in directory /var/lib/one/.ssh has files
[oneadmin@on-test ~]$ ll .ssh
total 40
-rw------- 1 oneadmin oneadmin 1444 Apr 16 00:12 config
-rw------- 1 oneadmin oneadmin 1381 Apr 30 14:32 id_dsa
-rw-r–r-- 1 oneadmin oneadmin 606 Apr 30 14:32 id_dsa.pub

-rw-rw-r-- 1 oneadmin oneadmin 1680 Apr 30 14:35 known_hosts
I do:
ssh-keyscan 192.168.10.171 >> /var/lib/one/.ssh/known_hosts
ssh-keyscan 192.168.10.169 >> /var/lib/one/.ssh/known_hosts
Then I do:
scp -rp /var/lib/one/.ssh root@192.168.10.169:/var/lib/one/
Current results:
Expected results:
I need to be able to connect via SSH without entering a passwordand and then I can connect the KVM to the node
