Hi list,
I was wondering is there a way to add multiple files to a vm via cloud-init using python SDK. I was able to add /etc/resolv.conf and additionally I would like to add config files for NICs (ifcfg-ethX) with appropriate values (ip,gw,netmask). I used an example given here: http://www.ovirt.org/Features/Cloud-Init_Integration . But unfortunately I cannot do the same thing If I want to write multiple files to a vm in params.Action class.
Thank you in advance! you can use the custom script text box in oVirts cloud-init
there you can add any cloud-init section - adding files examples can be found here:

Hi Shahar,
Thank you for the reply.
To be honest I knew for those scripts but I want to do it in automate fashion just like in that example that I put in my original message. I have tried to specify in params.Files class multiple files:
vm_file1 = params.Files(file=[params.File(name = 'file1', content = file1_content, type_= 'PLAINTEXT')]) vm_file2 = params.Files(file=[params.File(name = 'file2', content = file2_content, type_= 'PLAINTEXT')])
and then give them as arguments to params.CloudInit _init_ constructor (files=...) just like in that example above but it seems that I am doing something wrong because it does not write multiple files - it writes only when you specify one file all right. The exception is "Error: 'list' object has no attribute 'export'" (I tried to specify those files as a list
files=[vm_file1,vm_file2]).
Thanks for any help. The custom script is currently the only option to add files via Cloud-Init
Thanks, Shahar Havivi.
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). You don't need to use the GUI,

Hi Shahar, Thanks! I will try this one. I was not aware of this feature. Although I can see that it was mentioned on the list (my bad). Thank you for your effort! I really do appreciate it! Best regards, Branimir
