Translations:Managing your cloud resources with OpenStack/29/en

There are a number of ways to approach this, but basically what is needed is to add another public ssh key to the VM (see ssh keys about working with and creating keys). This could be done by adding to the authorized_keys of the primary user account provided for the VM, usually named after the operating system, or it could be added to a newly created user account. In Ubuntu, when logged in with the primary user's account this can be accomplished with the command

[name@server ~]$ sudo adduser USERNAME

Then add the supplied public key to that user's .ssh/authorized_keys file as described in ssh keys and linked pages.
