[ovirt-users] Re: hosted-engine-setup --deploy fail on Centos Stream 8

Hy, I am trying to install ovirt 4.5 on a 4-host cluster running Centos Stream 8, but the engine does not start and the whole process fails. Here is my procedure dnf install centos-release-ovirt45 dnf module reset virt dnf module enable virt:rhel dnf install ovirt-engine-appliance dnf install ovirt-hosted-engine-setup The latest version of ansible [ansible-core 2.13] uses python3.9 and the installation fails because some python3.9 modules are missing [python39-netaddr, python39-jmespath] and cannot be installed [conflict python3-jmespath]. So I downgraded ansible to ansible-core 2.12 dnf downgrade ansible-core

Now hosted-engine-setup --deploy --4 goes proceed further but stops because it cannot start the engine [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Wait for the host to be up] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Notify the user about a failure] [ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "Host is not up, please check logs, perhaps also on the engine machine"}

I looked into the log file /var/log//ovirt-hosted-engine-setup/ovirt-hosted-engine-setup-ansible-bootstrap_local_vm-20221007132728-yp7cd1.log and I found the following error: 2022-10-07 13:28:30,881+0200 ERROR ansible failed { "ansible_host": "localhost", "ansible_playbook": "/usr/share/ovirt-hosted-engine-setup/he_ansible/trigger_role.yml", "ansible_result": { "_ansible_no_log": false, "changed": false, "cmd": [ "virsh", "net-undefine", "default" ], "delta": "0:00:00.039258", "end": "2022-10-07 13:28:30.710401", "invocation": { "module_args": { "_raw_params": "virsh net-undefine default", "_uses_shell": false, "argv": null, "chdir": null, "creates": null, "executable": null, "removes": null, "stdin": null, "stdin_add_newline": true, "strip_empty_ends": true, "warn": false } }, "msg": "non-zero return code", "rc": 1, "start": "2022-10-07 13:28:30.671143", "stderr": "error: failed to get network 'default'\nerror: Network not found: no network with matching name 'default'", "stderr_lines": [ "error: failed to get network 'default'", "error: Network not found: no network with matching name 'default'" ], "stdout": "", "stdout_lines": [] }, "ansible_task": "Update libvirt default network configuration, undefine",

Has anyone had similar problems?
