Hello, is there a way to poweroff or reboot (without stopped and running state) a vm with the ovirt_vm ansible module? -- Nathanaël Blanchet Supervision réseau Pôle Infrastrutures Informatiques 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanchet(a)abes.fr

How to assign a server disk and nic profile via REST API?
by ovirt.org＠nevim.eu 02 May '21

02 May '21

Hello to everybody, for about an hour I have stuck my nose in the ovirt and rhev documentation, but I still can't understand how to use the REST API to change the disk profile and nothing the server profile. Ideally, how to set it for them when setting up a VM. Thank you so much for the advice.

oVirt Node's Future Regarding CentOS Stream
by eshwayri＠gmail.com 21 Apr '21

21 Apr '21

So I just finished migrating my 4.3 engine to 4.4 on a brand new RHvEL8 install; next step is to upgrade the hosts. When I first started with oVirt I used my own CentOS installs, but quickly decided that it made no sense for my use case. Now I am looking at upgrading from 4.3 to 4.4 and asking myself the same question. Up to now oVirt node has been using the same exact OS I would have used +/- a few extra packages, but with the traditional CentOS going away it really depends on what the new oVirt nodes are going to be based on. I have a feeling the answer to that question is CentOS Stream, which I don't feel comfortable with for this task. While I am sure the developers will test the combination before releasing a new node, they are still only testing whatever specific hardware combination they have. There could be numerous weird bugs that will only show up in certain situations. If Stream was as stable as an EL release, there wouldn't be EL releases. I also appreciate the fa ct that oVirt is itself a work in progress, but the stable branch is considerably more like an EL release than a stream. Anyway, back to the point. Just want to confirm the future for node is stream before I go wasting time building my own EL8 hosts.

Is it possible to upgrade 3 node HCI from 4.3 to 4.4?
by Jayme 20 Apr '21

20 Apr '21

I have a fairly stock three node HCI setup running oVirt 4.3.9. The hosts are oVirt node. I'm using GlusterFS storage for the self hosted engine and for some VMs. I also have some other VMs running from an external NFS storage domain. Is it possible for me to upgrade this environment to 4.4 while keeping some of the VMs on GlusterFS storage domains running? Does the upgrade require an additional physical host? I'm reading through the upgrade guide and it's not very clear to me how the engine is reinstalled on CentOS8. Do you need a 4th host, or do you take one of the three existing hosts down, wipe it and install ovirt node 4.4? Would it be easier for me to just move all VMs to my NFS storage domain, wipe all hosts and deploy a brand new 4.4 HCI cluster then import the NFS storage domain? Will the 4.3 VMs on the NFS storage domain import/run properly into the new 4.4 deployment or are there any other considerations?

Two selfhosted engines
by wilrikvdvliert＠hotmail.com 20 Apr '21

20 Apr '21

Dear forum, If I understand correctly, I need shared storage for the self-hosted engine to make it highly available. But is it possible to create 2 self-hosted engines on 2 hosts and make it high available this way? Kind regard

Introduction & general question about oVirt
by Nicolas Kovacs 20 Apr '21

20 Apr '21

Hi, I'm a 53-year old Austrian living in Montpezat, a small village in South France. I'm an IT professional with a focus on Linux and free software, and I've been a Linux user since Slackware 7.1. I'm doing web & mail hosting for myself and several small structures like our local school and a handful of local companies. Up until recently these hostings have happened on "bare metal" root servers using CentOS 7. One main server is hosting most of the stuff: WordPress sites, one OwnCloud instance, Dolibarr management software, GEPI learning platform, Postfix/Dovecot mail server, Roundcube webmail, etc. This setup has become increasingly problematic to manage, since applications have more and more specific requirements, like different versions of PHP and corresponding modules. So I decided to split everything up nicely into a series of virtual machines, each one with a nicely tailored setup. I have a couple of sandbox servers, one public and one local, running Oracle Linux 7 (a RHEL clone like CentOS). I played around with it, and KVM-based virtualization already works quite nicely. While looking for documentation, I stumbled over oVirt, which I didn't even know existed until last week. Before I dive head first into it, I'd be curious to know a few general things. 1. Would it be overkill for a small structure like mine? 2. Will I be able to do HA on a series of modest KVM-capable root servers even if they are located in different datacenters across different countries? 3. One problem I couldn't resolve using a bone-headed keep-it-simple KVM setup is backup. For my bare-metal servers I've been using incremental backups using Rsnapshot for years. Here's a blog article I wrote on the subject: https://blog.microlinux.fr/rsnapshot-centos-7/ Unfortunately I can't use this approach with huge QCOW images, at least not without jumping through burning loops. Is there an easy way to perform remote incremental backups with oVirt? BTW, I took a peek at Proxmox and Ceph, but I admit I'm a die-hard RHEL-clone user.

oVirt 4.4.4 not dislaying Sign-on Screen
by louisb＠ameritech.net 07 Apr '21

07 Apr '21

I recently installed oVirt 4.4.4, everything appeared to run successfully, however, I’m unable to get the sign-on screen to display on my RHEL 8.3 machine. I did do an install using the remote database installation. I encountered no issue with the install, I can see the “engine” and “ovirt_engine_history” in PostgreSQL 13.3. The tables and table spaces have all been created as designed by the installation process. When I enter the URL that was displayed once the installation completed I get the following information displayed on the screen: Internal Error I’ve tried using the port 443 and port 80 URL and get the same results. The URL are as follows: http://WorkstationName:80/ovirt-engine https://WorkstationName:443/ovirt-engine For three days I’ve been trying to locate logs that will help me located and resolve the problem, but so far I’ve had no luck. Can anyone tell where I should start looking to resolve my issue? I’ve checked several system logs and logs for Apache with luck. What should I be looking for within the logs? What logs should I be looking at? I don’t believe my issue is with the back-end database, I thinks its something with Apache not being able to find the web pages to display. How can I start to investigate my problem an develop a solution? My Linux/RHEL 8.3 OS has all of the latest patches and fixes applied. Thanks
