The on_boot parameter that you pass when creating the NIC is completely
ignored, like all the other IP configuration parameters.

But looking at your screenshot it looks like you are already using
cloud-init to solve this. Are you using those <nic>...</nic> XML
documents as part of larger request to create a VM? In that case we need
to check the complete XML document in order to see if there is something
wrong. Can you share it?
