I found communications over UDP:6081, which were fine by themselves. However, this helped to craft more targeted search requests which lead me to this discussion: https://lists.ovirt.org/archives/list/users@ovirt.org/thread/PVJJPK7MQOFL... Some suggestions there were helpful to at least become slightly more familiar with how the things work. Anyway, lack of documentation on this matter (I know that there are high-level old docs) does not help to resolve such cases.
