Normally, you add an ssh key and instruct VM to boot with that SSH key. When VM
is booted, cloud-init gets the metadata information about the vm (including the
SSH key you specify) add the ssh key to the user's .ssh/authorized_keys file.
You can look at the page below for managing ssh key via CLI tools. It would be
easier for you to manage them if you had dashboard. I would suggest you to
install it. It's as easy as installing other components of Openstack and it
makes management easier.


Please make sure that your networking components are working properly and you
have metadata proxy running. Otherwise, the VM will not be able to get your ssh
key and it will boot with empty ssh key. The usernames for the cloud images can
vary. For ubuntu, you need to login as "ubuntu" user, not "root".
