The custom script is currently the only option to add files via Cloud-Init

Hi Shahar,

Granted. But the example in python http://www.ovirt.org/Features/Cloud-Init_Integration uses custom script :) I just want to know how to do the same thing in case when I want to write more than one file to a VM - and yes  - all those multiple files that I want to write are specified via custom scripts.

From the link - (The "Python SDK" paragraph: scontent object holds the custom script):
 scontent = "write_files:\n-   content: |\n        search example.com\n        nameserver 10.10.10.1\n        nameserver 10.10.10.2\n    path: /etc/resolv.conf"
For example (and just for example), I want to write to /etc/issue and /etc/hosts not only /etc/resolv.conf. In essence, when vm goes to run-once mode I want to write more than one file to a vm via Python (using CloudInit) in automated fashion (and not touching oVirt GUI at all).

Thanks in advance!

Best regards,

Branimir
