Hi Marko,
it seems like an issue in ovirt_host_network Ansible module, Martin just posted a fix for that issue:

Subject: Ansible setup host network fails on comparing sorted dictionaries
Dear oVirt,
While deploying ovirt_infra , the role oivrt.networks fails on Setup Host Networks, with following error:
TypeError: '<' not supported between instances of 'dict' and 'dict'

Looking further into ovirt_host_network.py I found that issue is reported after following is executed:
return sorted(get_dict_of_struct(opt) for opt in new_options) != sorted(get_dict_of_struct(opt) for opt in old_options)
It seemed to be failing due to not getting the key value to sort the dicts, so I added sorting based on name, to test, and it worked in single test run:
return sorted((get_dict_of_struct(opt) for opt in new_options), key=lambda x: x["name"]) != sorted((get_dict_of_struct(opt) for opt in old_options), key=lambda x: x["name"])
After rerun of the play, with changes above:

Changes resulted in applying configuration exactly as intended.
