I been trying to install 4.5.5 testing and used the node installer iso. I cant login what is the username and password I have tried what others have done in the forums with no luck admin@ovirt . root admin . Also can the engine be installed from the node via the cockpit still? How can I get logged in to do this? I have used 4.3 and didnt have any of these problems. It was really simple to do. Any suggestions? grazie

Hi, I have 1 problem when using the Python SDK to make backups of virtual machine images, after updating to Ovirt 4.5. Before the update and with Ovirt 4.4 and Centos 8 everything worked. Scenario: Ovirt-engine - installed standalone, centos 9 Stream Host -> Centos 9 Strem - ISO used was ovirt-node-ng-installer-lastest-el0.iso Storage -> Iscsi Ovirt-backup -> Vm runnnig on host with centos 8 Stream with python3-ovirt-engine-sdk4 installed Versions: Version 4.5.6-1.el9 To reproduce the error, do the following: 1 -> Create a snapshot via interface GUI 2 -> Run this script to find my snaphot id ``` #!/bin/python import sys import printf import ovirtsdk4 as sdk import time import configparser import re cfg = configparser.ConfigParser() cfg.readfp(open("/opt/VirtBKP/default.conf")) url=cfg.get('ovirt-engine', 'api_url') user=cfg.get('ovirt-engine', 'api_user') password=cfg.get('ovirt-engine', 'api_password') ca_file=cfg.get('ovirt-engine', 'api_ca_file') connection = None try: connection = sdk.Connection(url,user,password,ca_file) # printf.OK("Connection to oVIrt API success %s" % url) except Exception as ex: print(ex) printf.ERROR("Connection to oVirt API has failed") vm_service = connection.service("vms") system_service = connection.system_service() vms_service = system_service.vms_service() vms = vm_service.list() for vm in vms: vm_service = vms_service.vm_service(vm.id) snaps_service = vm_service.snapshots_service() snaps_map = { snap.id: snap.description for snap in snaps_service.list() } for snap_id, snap_description in snaps_map.items(): snap_service = snaps_service.snapshot_service(snap_id) print("VM: "+vm.name+": "+snap_description+" "+snap_id) # Close the connection to the server: connection.close() ``` When i run the script i have the result of VM name + snap ID, so connection with api is OK. ``` [root@ovirt-backup-lab VirtBKP]# ./list_machines_with_snapshots_all VM: ovirt-backup: Active VM d9631ff9-3a67-49af-b6ae-ed4d164c38ee VM: ovirt-backup: clean 07478a39-a1e8-4d42-bdf9-aa3464ee85a2 VM: testes: Active VM 46f6ea97-b182-496a-89db-278ca8bcc952 VM: testes: testes123 729d64cb-c939-400c-b7f7-8e675c37a882 ``` 3- The problem occurs when I try to attach the snapshot to the VM I run the script below thats run perfect on previous ovirt version 4.4 and centos 8 ``` #!/usr/bin/env python # -*- coding: utf-8 -*- # # Copyright (c) 2017 Red Hat, Inc. # # Licensed under the Apache License, Version 2.0 (the "License"); # you may not use this file except in compliance with the License. # You may obtain a copy of the License at # # http://www.apache.org/licenses/LICENSE-2.0 # # Unless required by applicable law or agreed to in writing, software # distributed under the License is distributed on an "AS IS" BASIS, # WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. # See the License for the specific language governing permissions and # limitations under the License. # import subprocess import os import time DATE = str((time.strftime("%Y%m%d-%H%M"))) # In order to send events we need to also send unique integer ids.

Installing on iSCSI boot node
by rtartar＠gmail.com 30 Sep '24

30 Sep '24

I've installed the oVirt node on iSCSI boot server (Cisco UCS chassis) But when I go to add to the manager it fails and the Node loses contact with it's ibft interface. Anyway I can leave the interface alone when adding to the manager? I have 5 physical interfaces attached to the node. Any help would be greatly appreciated. Using the node 4.5 installer. I add the ip=ibft to the installation startup and seems to work mostly... Thanks in advance

Re: [External] : Error during hosted-engine deploy for Cluster Compatibility Version

Hello Marcos, I followed the guide and the suggestions provided by Ovirt Documentation. I didn't do any customisations, and it is a clean installation. How I can solve this? It seems there is a problem in normal installation process. Can you support? Thanks, Devis

Error during hosted-engine deploy for Cluster Compatibility Version
by devis＠gmx.com 30 Sep '24

30 Sep '24

Hi, I followed guide to install the oVirt Engine. I also used the suggestion to use oVirt master snapshot repositories. But during the installation I obtain the following error: "The host has been set in non_operational status, deployment errors: code 154: Host ********* is compatible with versions (4.2,4.3,4.4,4.5,4.6,4.7) and cannot join Cluster Default which is set to version 4.8., code 9000: Failed to verify Power Management configuration for Host *******., fix accordingly and re-deploy."} How I can solve this problem? I cannot find any suggestion on internet.

oVirt Node 4.5.5 no virtualization tab
by arkansascontrols＠icloud.com 26 Sep '24

26 Sep '24

I have installed 4.5.5 and can get to the Web Interface at :9090 on all 3. I have been able to add the SSH keys and from any of the 3 hosts web interface I can get to the others from the drop down. But there is no Virtualization Tab on any of the 3, so no way to create VM's. I have followed a few instructions from some threads I've found on here https://www.ovirt.org/dropped/gluster-hyperconverged/chap-Deploying_Hyperco… I subscribed all 3 hosts to the repo, and installed the engine, but the cockpit-ovirt-dashboard doesn't exist to install, and I'm guessing that's where I will find what I need to make this usable. Any help would be appreciated.

Installation issue
by dave nirav 25 Sep '24

25 Sep '24

Hi, Probably this is my first mail to this list. I am facing lot of dependency issue while installing ovirt-engine, moreover on getting openstack, ceph and ansible. I have specified the repo paths in /etc/yum.repo.d/<>, it seems openstack path show EoL and I am unable to install its dependent packages. I am working on limited env with customization over RHEL9 though I am not having any RHSM support. I am installing things 1 by 1 and would like to get help on the installation steps and list of rpms needed to do engine-setup. Any help will be appreciated. dnf install ovirt-engine Last metadata expiration check: 1:41:11 ago on Wed Sep 25 11:35:58 2024.

Migrating Self Hosted Engine from el8s to Standalone Hosted Engine using el9
by Nur Imam Febrianto 25 Sep '24

25 Sep '24

Hi. Currently we're using oVirt 4.5 that still based on el8s (Both host end the engine), because CentOS 8 Stream had been EOL'ed we want to migrate the engine using Standalone Engine (not the self hosted) and uses any el9 capable OS. What is the proper way to do it ? And after the migration what will happened to storage domain that used by the Self Hosted Engine in el8 ? Maybe anybody here can give me some good advise. 🙂 Thanks before. Regards, Nur Imam Febrianto

API to Query OVA files from the hosts/ mounted locations
by Siddu Hadpad 24 Sep '24

24 Sep '24

We are storing images in an NFS share that will be mounted to KVM hosts. When I attempt to provision a VM using the mounted path, it successfully provisions the VM from the OVA files. However, if an incorrect path is provided, it results in an 'Operation Failed' error. The error message is not so descriptive. To prevent this issue, I'd like to validate if the OVA file already exists in the specified path. Unfortunately, I haven't been able to find any APIs to query images directly from mounted locations on the host. While the web UI does display an error if an incorrect path is provided, I'm wondering if there are any APIs available to validate the presence of the OVA file in the specific path.
