Re: [ovirt-users] cloud-init options under python-sdk

hello Juan|guys, I still have problems with cloud-init options on python-sdk... now I'm trying to reset root password and according to xml available at http://www.ovirt.org/Features/Cloud-Init_Integration and specifically for user/pw: ... <users> <user> <user_name>root</user_name> <password>myPass</password> </user> </users> ... I've changed action object with this example: action = params.Action( vm=params.VM( initialization=params.Initialization( cloud_init=params.CloudInit( host=params.Host(address="rheltest025"), users=params.Users( user=params.User(user_name="root", password="pippo")

) ) ) ) ) but when i try to start a vm I got this error: "TypeError: 'User' object is not iterable" somebody has some hints for resetting root password?
