I think I found the problem. The regex in 001_validate_network_interfaces.yml really wants there to be a number after the 'bond' identifier, i.e. bond0. However, the regex is as follows:
bond_valid_name="{{ iface_item | regex_search('(^bond[0-9]+)') }}"
which will not return a good value if just 'bond' is passed to it (the output of nmcli -g GENERAL.TYPE device show).
However, I am not an ansible expert, nor am I an expert on how these scripts are called. I humbly request someone else's expert opinion on this.
Thanks again.
I think the main failure reason is about the current bonding mode: balance-rr that is not supported:
Actually here below in hosted engine installation guide:
is stated:
"
If the ovirtmgmt network is not used by virtual machines, the network may use any supported bonding mode.
"
But in 001_validate_network_interfaces.yml there is:
- name: Set variable for supported bond modes
set_fact:
acceptable_bond_modes: ['active-backup', 'balance-xor', 'broadcast', '802.3ad']
and then a when condition with
hostvars[inventory_hostname]['ansible_' + iface_item]['mode'] in acceptable_bond_modes
so that the balance-rr interface is filtered out.
Not digged about the "false" positive regarding messages about only team devices detected...
HIH,
