I figured it out: I noticed that the cockpit was running this command: /usr/bin/python3.8 /usr/bin/ansible-playbook /usr/share/ovirt-hosted-engine-setup/ansible/trigger_role.yml --tags=get_network_interfaces --skip-tags=always -e he_just_collect_network_interfaces=True --module-path=/usr/share/ovirt-hosted-engine-setup/ansible --inventory=localhost ERROR! the playbook: /usr/share/ovirt-hosted-engine-setup/ansible/trigger_role.yml could not be found The directory "/usr/share/ovirt-hosted-engine-setup/ansible" doesn't exist. It looks like it was renamed to "/usr/share/ovirt-hosted-engine-setup/he_ansible" This command that I ran on all three nodes worked around the bug: ln -s /usr/share/ovirt-hosted-engine-setup/he_ansible/ /usr/share/ovirt-hosted-engine-setup/ansible I created a pull request https://github.com/oVirt/cockpit-ovirt/pull/27/commits Thanks, Dax Kelson On Wed, Jul 6, 2022 at 3:03 PM Dax Kelson <daxkelson@gmail.com> wrote:

TL;DR hyperconverged install. Gluster install works, hosted engine fails with "no valid network interface has ben found"

I have a three node hyperconverged cluster that had previously been running oVirt 4.4 successfully.

A fully wipe and clean install of 4.5.1 was attempted with:

ovirt-node-ng-installer-4.5.1-2022062306.el8.iso

On each node, there are two statically configured 10Gb ethernet interfaces (and some unused 1Gb interfaces)

enp5s0f0 - ovirt management/VM network (default gateway is on this network) enp5s0f1 - gluster network (isolated network)

Name resolution is done via /etc/hosts on each node:

100.64.0.7 node1-ovirt node1-ovirt.local 100.64.0.8 node2-ovirt node2-ovirt.local 100.64.0.9 node3-ovirt node3-ovirt.local 100.79.192.1 node1-ovirt-storage node1-ovirt-storage.local 100.79.192.2 node2-ovirt-storage node2-ovirt-storage.local 100.79.192.3 node3-ovirt-storage node3-ovirt-storage.local

Attempting to install the hosted engine fails with:

*System data could not be retrieved!* *No valid network interface has been found* *If you are using Bonds or VLANs Use the following naming conventions:* - VLAN interfaces: physical_device.VLAN_ID (for example, eth0.23, eth1.128, enp3s0.50) - Bond interfaces: bond*number* (for example, bond0, bond1) - VLANs on bond interfaces: bond*number*.VLAN_ID (for example, bond0.50, bond1.128) * Supported bond modes: active-backup, balance-xor, broadcast, 802.3ad * Networking teaming is not supported and will cause errors Here is the network setup on node1:

My troubleshooting is that the failure is /probably/ coming from this file, but I'm not sure why:

/usr/share/ansible/collections/ansible_collections/ovirt/ovirt/roles/hosted_engine_setup/tasks/pre_checks/001_validate_network_interfaces.yml

Help?
