[ovirt-users] the difference to set the cloud-init via api/sdk between 3.5 and 3.6

[pc]

Hi there,
I upgraded ovirt from 3.5.4 to 3.6.0 last weekend.  Here is  what I found: cloud-init relatied api/sdk failed to work which was effective on 3.5
[conclusion]the difference is whether to use this:  <use_cloud_init>true</use_cloud_init>

[what I want] 1) How to find more docs for api/sdk?2) Is there anything (such as change log, tutorials ) for ovirt api/sdk upgrade?3) How to use cloud-init in ovirt-engine-sdk-python-3.6.0.3 ?
