Preparing to issue an oVirt release post Red Hat offboarding
by Sandro Bonazzola 01 Nov '24

01 Nov '24

Hi, Oracle fixed CVE-2024-7259 ( https://github.com/oVirt/ovirt-engine/security/advisories/GHSA-8xjm-j7fq-3w… ) in oVirt Engine and would be nice to issue an oVirt Engine release including the fix. As the current master also includes support for new cluster level 4.8, VDSM needs to be released as well providing cluster level 4.8. As you know, Red Hat offboarded the project and as such there are no more people officially assigned to the project from the company, despite a few of the historical developers still spend some of their free time helping out. I can help building the packages and getting them out on my free time but I have no capacity for doing any testing or documentation updates or release notes related to this release. Last oVirt Engine (4.5.6) was also released last February without any formal release announce. Any volunteer to look into differences between current master and current stable release and see if anything else needs to be released other than ovirt-engine and vdsm? Any volunteer to write release notes and update the website accordingly? Any volunteer to run ovirt-system-test on https://github.com/oVirt/ovirt-engine/pull/970 and https://github.com/oVirt/vdsm/pull/422 as OST doesn't run anymore on GitHub? Regards, -- Sandro Bonazzola

Installation of hosts on RHEL9
by Fabrice Bacchella 31 Oct '24

31 Oct '24

Hi, I’m migrating to oVirst 4.7 and RHEL9. The engine is up and running but I have problems testing adding new hosts. It fails running the command: sudo vdsm-tool ovn-config $IP $FQDN. The message is Traceback (most recent call last): File "/usr/lib/python3.9/site-packages/vdsm/tool/ovn_config.py", line 118, in get_network return networks[net_name] KeyError: '$FQDN' And indeed if I print net_caps in the method net_caps of ovn_config, it says: {'networks': {} ... I have been unable to understand where this information is coming from, what is missing in my host ? Are they the networks as configured in the engine ?

HostedEngine VM doesn't start because in QXL video type mode
by Mario Indelicato 31 Oct '24

31 Oct '24

Hi, I don't know how this happened but after an host reboot, the HostedEngine VM didn't started anymore. The error in the log is: "unsupported configuration: domain configuration does not support video model 'qxl'" This is a single host test environment, OS is Rocky 9.4, so I know it's expected that QXL video is not supported anymore. I tried editing the HostedEngine VM configuration via virsh, but when I start the VM it keeps trying to use QXL. Also the VM conf in "/var/run/ovirt-hosted-engine-ha/vm.conf" says the video type is always QXL. I tried dumping the XML configuration, edit the XML, undefined e re-define the VM from the updated XML, but still it uses QXL!!! I'm resigned myself that the only solution is to re-deploy the HostedEngine from scratch. Unless some of you can provide an alternative solution. Many thanks in advance Mario

Re: [External] : Lost console access to VMs after updating

Malcom, here the solution to your actual issue: Replace the following file with the attached one: # /etc/httpd/conf.d/olvm45-security-fixes.conf The final fix will be there with release ending with .23.

Add existing KVM host to oVirt
by gabrielappugliese＠gmail.com 25 Oct '24

25 Oct '24

Hello, I just installed oVirt as a standalone Manager with local databases and i deployed it on a VM thats inside the KVM host i want to add to it. I get its not best practoce but its for a personal lab and i setup ssh to only allow root from the vm where oVirt is installed...anyways i attempted to add the host but its failing with this error ... No package ovirt-hosted-engine-setup available ... to make "ovirt-hosted-engine-setup" available im assuming i have to enable the repositories (Following this guide https://ovirt.org/download/install_on_rhel.html) to make it available but will doing all that allow me to add the kvm host which already has VMs deployed on it able to be managed by ovirt? would this help me achieve what im trying todo? https://ovirt.org/documentation/installing_ovirt_as_a_standalone_manager_wi… Thanks in advance

Re: [External] : open v-switch woes
by Tim Walsh 25 Oct '24

Yes, not only a desire to replicate the functionality of V-Switches on VM-Ware, but also to have an isolated test environment. Create a virtual firewall (using Opensense or pfSense or something) and create VMs behind the firewall that can all talk to each other, but the firewall only passes out the application traffic (for example a web app on Nginx, or Remote Desktop to the private Environment). Microsoft Hyper-V has "private" and "internal" switches that can be set up, (and thats the case on either a standalone or a cluster) so I figured oVirt must have something similar if not the same. these may or may not necessarily be tagged to a VLAN on a physical switch.

Hello. I did installed "ovirt-node-ng-installer-latest-el9.iso" and that is all. I'm able to login now to Cockpit on port 9090 but only when I manualy set ip adress in form. https://{ip_address}:9090/={ip_address}/system There is no way to login normaly. When I just try https://{ip_address}:9090 then it want to login to Server: some-hostname-ovirt and it doesn't work. I should do reverse engineering to understand why it doesn't work but I don't have time for it at the moment. In my configuration I need to use specific VLAN in network configuration. Maybe that is why there is no way to login. I have never used Keycloak. I'm not new in Linux world but I'm a noob in RHEL world. I would prefer to use Proxmox instead of trying to configure oVirt but it will not work with MegaRaid unless I will reflash the controller. Debian have huge problems with Praid CP400i and my old server still have some potential to be working as VM host. Is there any tutorial what to do in oVirt? Maybe some oVirt for absolute dummies? Is oVirt the kind of system that needs to be carved in marble? I'm not able to do advanced stuff on it now. It will take me a lot of time to get to this point. At the moment I'm interested in creation basic server for VM to see will it work fine but it seams it is not so easy to start with.

Hello what about the implication of team.blue which announced a job advert to continue to develop ovirt? It has been published in July but is not available anymore.

Importing Storage Domain's Export from one Data Center to Another
by calebmibaker＠outlook.com 24 Oct '24

24 Oct '24

Is it possible to perform disaster recovery importing a Storage Domain's Export from one Data Center to another in a manually fashion without Ansible? I'm trying to import Data Center 1's Storage Domain Export by cloning the storage domain export and importing it into Data Center 2's environment through IP address & NFS name within the oVirt's web portal. However, I receive this error message: there is no storage domain under the specified path. Below is what I have done to tried to troubleshoot the issue. After looking into the documentation, I haven't seen information for this method. Should I consider another option? Is there a preferred way of testing DR within an environment? -I have detach both of the export storage domains from both data centers before importing the cloned export. -Changing import settings -I have adjusted the metadata information within the cloned export after mounting it and reviewing the logs.

Migration of oVirt Engine and Hosts from CentOS 8 to CentOS 9
by narutospinal＠gmail.com 24 Oct '24

24 Oct '24

Dear, I would like help with the following question: I need to migrate my oVirt Engine and oVirt Hosts from CentOS 8 to CentOS 9. My plan is to back up the database using the engine-backup command. For example: engine-backup --mode=backup --file=db_backup My next step will be to install the oVirt Engine on CentOS 9 and restore the backup. For example: engine-backup --mode=restore --file=db_backup --log=backup_restore.log --change-db-credentials --db-host=didi-lap --db-user=engine --db-password=your_password --db-name=engine Finally, I will add a new oVirt Host with CentOS 9 and migrate the virtual machines. Are there any considerations I should be aware of? Could you please guide me?

I'm not sure why. It may be related with hardware firewall configuration and multiple vlans I use. Cockpit works with root and password but only if ip address is given. I did also try using login with @ sight and it didn't help. Command ovirt-aaa-jdbc-tool doesn't work. I also can't install nano, "ovirt-aaa-jdbc-tool", and mc. But internet connection is working and I can resolve DNS addresses. Maybe RHEL type of Linux is not so bad but I'm not familiar with it.

I am running Rocky Linux 8.9 and oVirt 4.5.5 (el8) I got the repos but online feedback recommends installing openvswitch, and ovn-northd, ovn-central and ovn-host I got openvswitch installed, but the other three: ovn-northd, ovn-central and ovn-host seemt o be elusive even after adding the CentOS-Advanced-Virtualization.repo and uipdating all "CentOS-" repost to point to "vault" instead of "mirrorlist" Can someo0ne help me with what I'm missing? I've tried Bing CoPilot and ChatGPT LOL but they say add that repo and install those packages. Thanks, Tim

Importing Storage Domain's Export from one Data Center to Another
by fodfateofdeath＠yahoo.com 21 Oct '24

21 Oct '24

Is it possible to perform disaster recovery importing a Storage Domain's Export from one Data Center to another in a manually fashion without Ansible? I'm trying to import Data Center 1's Storage Domain Export by cloning the storage domain export and importing it into Data Center 2's environment through IP address & NFS name within the oVirt's web portal. However, I receive this error message: there is no storage domain under the specified path. Below is what I have done to tried to troubleshoot the issue. After looking into the documentation, I haven't seen information for this method. Should I consider another option? Is there a preferred way of testing DR within an environment? -I have detach both of the export storage domains from both data centers before importing the cloned export. -Changing import settings -I have adjusted the metadata information within the cloned export after mounting it and reviewing the logs.

How to create templates better

I have multiple data centers. I use additional storage domains to attach to other data centers. When I import a template, it prompts that the Template ID already exists in the system. How should I modify the template ID or is there a better way? For example, a template can be used in all data centers
