> On libcloud/compute/ssh.py we specify password OR public key to ssh to a cloud server. This results in deploy_node to fail to ssh to a server where it allows PubkeyAuthentication only (example HPCloud servers). 
> However there's no need to specify only one of the two, both can be specified. Paramiko's authentication is attempted in the following order of priority: 
> (from paramiko/paramiko/client.py)
> public key(s) passed, 
> any key found through an SSH agent,
> any "id_rsa" or "id_dsa" key discoverable in ~/.ssh/,
> plain username/password auth, if a password was given 
> I've tried the patch on several backends (including HPCloud) and it worked without issues
