Hi,<br>
<br>
The OpenNebula user creation must be done by oneadmin. If you don't<br>
want to use the OpenNebula CLI commands you should implement an<br>
application for managing the account creation, for example a portal or<br>
maybe extend the Sunstone implementation [1].<br>
<br>
Also you could extend one of the Public Cloud implementation (OCCI<br>
[2,3] and EC2 [4,5] interfaces). The users will be able to access the<br>
cloud using a client that will interact with OpenNebula through a<br>
server, allowing multiple users at the same time<br>
