Facing problem of Authenticity problem of SSH after doing password less ssh.
Error Message: Authenticity can’t be established:

Assuming it’s one of the images made by the opennebula team, it won’t have a password.
The only way to access it is setting your public ssh key in the User settings (or directly in the VM Template) before the VM is created.

Thank you for your reply, After setting public ssh key (Id_dsa.pub) in user
setting of VM before its creation, VM asked for username and password.

Please guide us to solve this problem.
