Note that at step 3 the ssh-copy-id command is just one possible method of uploading your public key to the server and it may or may not be applicable depending on the type of server and what sort of access you already have to that server. The example command I provided will work if you have ordinary ssh access to the server using password-based authentication.

Unable to connect to the AWS EC2 instance - “Host key verification failed”. But when I try to do SSH, it's not allowing me for the remote login and throws errors like: Host key verification failed. A new instance with the same IP your computer will complain of 'Host verification failed' as its previously stored pair no longer matches. May 06, 2016 Failed Verification of Client Public Key.

Thank you, @newzen . I've encountered similar issues when importing KVM virtual machines from libvirt via ovrit webUI. Your approach works well. On the host into which the KVM virtual machines will be imported, run |
