Latest 4.5.5 centos node install username password not working.
by antonio.riggio＠mail.com
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?

Error attach snapshot via python SDK after update to ovirt 4.5
by luis.figueiredo10＠gmail.com
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

This is scenario on my LAB Test, in production i have 4 hosts, 3 on Centos 8 and 1 on Centos 9 Ovirt node image, and if my ovirt-backup machine running on host with centos 9 Ovirt Node i have the same error that mentioned above, but if i migrate my ovirt-backup to another host with Centos 8 do not have this problem.
Any idea what could cause this problem?
Sorry if my English isn't understandable
Thanks

Installing on iSCSI boot node
by rtartar＠gmail.com
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

Error during hosted-engine deploy for Cluster Compatibility Version
by devis＠gmx.com
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
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_Hyper...
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
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.

Migrating Self Hosted Engine from el8s to Standalone Hosted Engine using el9
by Nur Imam Febrianto
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.

API to Query OVA files from the hosts/ mounted locations
by Siddu Hadpad
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.
