New oVirt HCI 4.5.4 Cluster Problems
by Clint Boggio 14 Feb '23

14 Feb '23

Good day all. I'm in the process of deploying a fresh, new cluster and i'm running into a few snags. I'm trying to use the cockpit environment to deploy the gluster storage setup as I have previously done and it's failing consistently. I looked through what I believe to be the current documentation and I don't see anything about HCI setup, and the Gluster storage documentation points to the Gluster community web presence. So, my question is, will the oVirt HCI deployment still be supported, and is the process the same with cockpit to configure the storage, and cli to deploy the hosted engine or did HCI and gluster not make the cut with the 4.5.4 release? I'm using the oVirt node installation iso from the oVirt site for this deployment.

future of oVirt after end of road for CentOS. (porting)
by rp.neuli＠yahoo.com 12 Feb '23

12 Feb '23

Hello Masters, I am very keen to use oVirt, but I was shocked and shaken to go ahead with oVirt after I heard about end of road for CentOS. Therefore I looked for some answers which I could not find online: 1. Will/Are you actively and vigorously porting: a) oVirt Agent to other OS like ubuntu? b) vdsm package to other OS like ubuntu, deb, openBSD etc. 2. While standalone oVirt Node can continue to have CentOS codebase under the hood. But do you still want to migrate it to other OS? like openBSD? Kindly advice. In my view, oVirt in itself is a good and complete platform. It just need to continue evolve as VM and container "OS"/hypervisor. At the same time 'agent' and vdsm should be ported to as many OS as possible. Thank you. Rajeev

oVirt 4.5 console problem with Ubuntu 22.04 guest
by Kalil de A. Carvalho 12 Feb '23

12 Feb '23

Hello all. Today I had a problem trying to connect with some VM's using console vnc, through user portal, informing us that other one was connected already, asking if we want to connect anyway, and after we accepted it show us a information that was not possible connect, that has some problem synchronize with de SSO, that is probably error with the guest agent. We tried restarting the agent but had the same result. Just after shutdown and starting again all things worked fine. We looked for any firewall rule, errors between communication and we did not find anything. Does anyone have this kind of problem? We have other O.S and distribution working fine here, just have this problem with Ubuntu 22.04. Best regards -- Atenciosamente, Kalil de A. Carvalho

ImageIO Performance
by Jean-Louis Dupond 11 Feb '23

11 Feb '23

Hi All, We backup our VM's with a custom script based on the https://github.com/oVirt/python-ovirt-engine-sdk4/blob/main/examples/backup… example. This works fine, but we start to see scaling issues. On VM's where there are a lot of dirty blocks, the transfer goes really slow (sometimes only 20MiB/sec). At the same time we see that ovirt-imageio process sometimes uses 100% CPU (its single threaded?). Is this known behavior? Are there ways to optimize imageio? Or any other ways to improve the download speed? Thanks Jean-Louis

{REQUEST} oVirt (including RHHI) as HCI in the future
by 樽井周久（KTCSP） 10 Feb '23

10 Feb '23

To whom it may concern I have been using oVirt in an HCI environment for over 5 years. The reason why I chose oVirt (most attractive point of oVirt for me) was that it is easy to build an HCI environment with GUI deployment. Now, I found out that the deployment by GUI has been deprecated (from ovirt4.5) on your forum site, and that all the contents related to HCI were deleted (dropped) in your official installation guide site. https://lists.ovirt.org/archives/list/users@ovirt.org/message/CBDUBBKLTCW4M… https://www.ovirt.org/documentation/installing_ovirt_as_a_self-hosted_engin… It seems that oVirt will not be able to build HCI environment in the future. So I'm very worried about whether I can continue to use oVirt as before. I would appreciate it if you could tell me about your prospects regarding oVirt as HCI. For your reference below. On 4.5.3 oVirt host, Gluster deployment was done with GUI, but hosted-engine had to be deployed with CLI. On 4.5.4 oVirt host, Guster deployment failed with GUI, so subsequent hosted-engine deployment could not proceed. ('str object' has no attribute 'vgname') Best regards, Kanehisa Tarui Tokyo, Japan

OS moves after reboot to different device
by simon＠justconnect.ie 07 Feb '23

07 Feb '23

Hi All, I just built a 3 node cluster (4.5.2) with 3 Virtual Disks on identical Dell Servers. First Virtual Disk /dev/sda - BOSS Card - 450GB Second Virtual Disk /dev/sdb - SSD 14TB Third Virtual Disk /dev/sdc - HDD 72TB All OS disks were /dev/sda before reboot Following reboot only first Node is still /dev/sda - other 2 nodes are now /dev/sdc This obviously makes it impossible to create VG groups and create Gluster storage volumes. Can anyone shed any light on why this is happening and how to prevent it. Kind regards Simon

oVirt 4.6 planning
by Sandro Bonazzola 07 Feb '23

07 Feb '23

oVirt developers community, I see there are a few enhancements submitted in GitHub: engine: Add amt_ws fence agent support <https://github.com/oVirt/ovirt-engine/pull/810> Notification emails merging and localization <https://github.com/oVirt/ovirt-engine/pull/798> And also some rebase proposal: Rebase on WildFly 26 <https://github.com/oVirt/ovirt-engine/issues/637> Which would probably make more sense to be targeted to an oVirt 4.6 than a 4.5.z. There are now about three hundreds Untargeted issues(no milestone set) <https://github.com/issues?q=is%3Aopen+is%3Aissue+user%3Aovirt+archived%3Afa…> to be triaged and about sixty Untargeted PRs (no milestone set) <https://github.com/pulls?q=is%3Aopen+is%3Apr+user%3Aovirt+archived%3Afalse+…> to be reviewed. Some of them might be ready for a 4.5.z bugfix release while others can wait for a 4.6. Anyone willing to step in to lead the oVirt 4.6 development? A year has passed since my blog post about the future of the oVirt project <https://blogs.ovirt.org/2022/02/future-of-ovirt-february-2022/> but the concept is the same: oVirt future depends on how you, the community! Come help contribute to this new future <https://ovirt.org/develop/>! CC users community in case someone wants to jump into development as well.

Ovirt Hosted Engine - Offline Deployment
by will.roberts＠penten.com 07 Feb '23

07 Feb '23

Hi Team, I need some help deploying Ovirt Hosted Engine. I have installed Ovirt Node 4.5.4 on my intel NUC as a small development environment for a bigger project. I am not able to connect the NUC to the internet but am able to download any relevant packages onto a hard drive and connect this to the system. I have attempted to deploy Hosted Engine via the CLI with the following command: "hosted-engine --deploy --4 --ansible-extra-vars=he_offline_deployment=true". This Fails as it is unable to resolve the URL for the mirror? I feel as though I must be missing some pre-deployment step which changes the repo path but my knowledge in this area is definitely not where it needs to be. I've trolled through the internet but cant find any sort of documentation which details the involved steps. Does anyone have any knowledge on how do accomplish this with my previously mentioned restrictions?

PKIX path validation failed: java.security.cert.CertPathValidatorException: validity check failed
by Roberto Nunin 06 Feb '23

06 Feb '23

We are receiving this message into engine web page, surprising us due to certificate renewal done three months ago, during upgrade from 4.5.2 to 4.5.3. Infact, all certificates are valid, with only two exceptions: In /etc/pki/ovirt-engine/certs, apache.cer and websocket-proxy.cer were reporting expired certificates. We've done the defined action to renew certificates, with engine-setup --oflline and everything goes smoothly, but instead of two 5-years valid SSL certificates, we've got 2 1-year valid (more or less): #openssl x509 -noout -startdate -enddate -in websocket-proxy.cer notBefore=Feb 4 20:59:14 2023 GMT notAfter=Mar 9 20:59:14 2024 GMT #openssl x509 -noout -startdate -enddate -in apache.cer notBefore=Feb 4 20:59:14 2023 GMT notAfter=Mar 9 20:59:14 2024 GMT It's the correct behaviour ? I'm already aware about web SSL certificate duration "restriction" to 1-year, but all other certs have a 5-year validity. Here's one of: #openssl x509 -noout -startdate -enddate -in vmconsole-proxy-user.cer notBefore=Nov 20 11:11:08 2022 GMT notAfter=Nov 22 11:11:08 2027 GMT This post just for confirmation that this is correct behavior.

How to assign user rights more precisely
by ziyi Liu 06 Feb '23

06 Feb '23

I have configured ldap and can use ldap users to log in to the web engine There are many data center clusters and virtual machines in my environment. I should have more precise control over users The general manager can see several data centers he manages and can manage them There are three employees, A, B, and C, under the general manager. These three employees manage these data centers separately, and I want the three employees of A, B, and C to not be able to see each other's data centers.

Ovirt Rename multiple disks
by Pietro Pesce 03 Feb '23

03 Feb '23

Hi I'm new to using ansible, I'm writing a playbook to install a vm from template, everything works fine except for the disk names which stay the same as the template. The vm has more than one disk attached, I found this works for renaming the disk, but it only renames 1. how can I rename the others too? - name: Print vm attributes ovirt.ovirt.ovirt_vm_info: auth: "{{ ovirt_auth }}" pattern: name="{{ vm_fqdn }}" fetch_nested: true register: vm_info - debugging: msg: "{{ vm_info.ovirt_vms[0] }}" - name: Rename disk ovirt.ovirt.ovirt_disk: auth: "{{ ovirt_auth }}" id: "{{ vm_info.ovirt_vms[0].id }}" storage_domain: lrg0-ovirt-mydom-internal-Local name: "{{ vm_fqdn }}-osdisk0" vm_name: "{{ vm_fqdn }}" Thanks Regards

Re: CPU Shares
by Marcos Sungaila 03 Feb '23

03 Feb '23

Hi Nick, Setting CPU Shares only changes how the instance works. It does not affect the current workload unless the instance is under pressure. For example, if you are running an RDBMS, you may see a performance improvement when normalizing the database or generating a monthly report. Even that, the improvement may be minimum. Do not expect a sensible performance improvement for normal operation. Performance tuning is not magic. You will often perform many configurations to see a 1%, maybe 2% gain. Regards, Marcos From: Nick --- <jsmith1299(a)live.com> Sent: Wednesday, February 1, 2023 9:59 AM To: users(a)ovirt.org Subject: [External] : [ovirt-users] CPU Shares Hello, I would like some help understanding CPU shares. We have several VMs which are CPU pinned due to licensing. We would like to favor one VM since it is our application VM over the other VMs which it is pinned with. Would I set the CPU share on the one that needs to priority to high or low? In the documentation I see the following: Specify CPU Shares. Possible options are Low, Medium, High, Custom, and Disabled. Virtual machines set to High receive twice as many shares as Medium, and virtual machines set to Medium receive twice as many shares as virtual machines set to Low. Disabled instructs VDSM to use an older algorithm for determining share dispensation; usually the number of shares dispensed under these conditions is 1020. I currently have it set to high and I believe it is doing the opposite of what I want it to do as the CPU steal percentage appears to be 10-15% over the other VMs which show no CPU steal and are set to low. I'd like to confirm if I have this setup correctly or not. Thanks, Nick

Re: Self-hosted engine 4.5.0 deployment fails

I would run the deploy again, wait until the engine is up and then from the server you are deploying the engine on # virsh list obtain the virtual machine number from the above command, in the example below we assume the number is 1 # virsh console 1 login as root wait for all packages to finish updating: tail -f /var/log/dnf.rpm.log then: # dnf downgrade postgresql-jdbc once that's done the deployment of the engine should get past the [ INFO ] TASK [ovirt.ovirt.engine_setup : Check if Engine health page is up] step.
