I'm using Create Server Api ( to create an instance. This api creates the instance successfully, and returns the response as below :

{ "server": { "security_groups": [ { "name": "default" } ], "OS-DCF:diskConfig": "MANUAL", "id": "c6d04159-9bfc-4ab8-823d-0d5ca2abe152", "links": [ { "href": "", "rel": "self" }, { "href": "", "rel": "bookmark" } ], "adminPass": "aabbccddeeff" } }

In response, we recieve a password as adminPass. I tried logging into the instance from console using that password, but none of the username like admin,root or server name works. So I'm unable to log into the instance.

Can anyone please help me with which username to be used?

Advance thanks for any help provided.

Thank You, Guru Prasad.K.V

Just because the api generates an admin password does not mean that the instance you are booting is going to take advantage of that password. What operating system are you booting? If Linux, which distribution?

I don't believe cloud-init, the tool that Ubuntu and other distributions use to configure instances from OpenStack metadata, has any support for adminPass. What cloud-init does is read the ssh key you provided when you booted the instance and provisions that into the ubuntu user account (for Ubuntu; cloud-user or ec2-user for various CentOS/Fedora/RedHat versions).

If you have properly configured an ssh key when booting your instance, you should then be able to:

ssh ubuntu@your.instance.ip

And have access without a password. From this account you can use sudo to gain root privileges.
