As I said in previous posts I used this Python example http://www.ovirt.org/Features/Cloud-Init_Integration to set root password, hostname and resolv.conf. It worked without any problems for 3.4 oVirt version and equivalent Python SDK (ovirt-engine-sdk-python-3.4.x.noarch). Then, I have tried to write through yuml scripts more conf files than just resolv.conf to configure guest. I also saw this post on the list: http://lists.ovirt.org/pipermail/users/2014-October/028539.html. So based on that, I decided to upgraded oVirt and SDK (ovirt-engine-sdk-python-3.5.0.7-1.el6.noarch) to 3.5 version. The upgrade itself passed without any problem. >From that point forward I tried to use custom_script parameter (as suggested by Shahar) inside Initialization class and CloudInit class without any luck. Can somebody please provide a simple Python code to submit yaml script to cloud-init? Also after the upgrade the example script I mentioned above can only change hostname. It does not write resolv.conf anymore nor it sets root password. I don't know if something is changed inside methods? For example, customization of virtual machine (memory,cpu,high availability, pinning to a certain host etc works without any problems). Thank you! Best regards, Branimir
