Images upload - Content Security Policy
by jiri.mikulas＠mibcon.cz 08 Nov '24

08 Nov '24

Hello I'm using Oracle Linux with ovirt-engine 4.5.5-1.22.el8 Operating System: Oracle Linux Server 8.10 Kernel: Linux 5.15.0-301.163.5.2.el8uek.x86_64 After upgrading from ovirt-engine version 4.5.5-1.21.el8 to version 4.5.5-1.22.el8, there seems to be an issue with uploading images. When trying to test the connection for uploading images using Storage -> Domains -> MyStorage -> Disks -> Upload I debugged network communication in "chrome inspect" and received the error: "Refused to connect to https://ovirt-engine:54323/info/ because it appears in neither the connect-src directive nor the default-src directive of the Content Security Policy." Has anyone encountered this problem? I have the CA certificate properly imported since version 4.5.5-1.21.el8, where the uploads worked normally. Regards Jiri

Adding ISO doesn't work
by sol-pl-cm＠nttdata.com 08 Nov '24

08 Nov '24

I have a problem adding ISO. Fresh installation of OracleLinux-R8-U10 with Ovirt Version:4.5.5-1.22.el8 installed on it. I've already gone through all possible forums and threads with a similar problem, but none of them have been solved, and I haven't been able to solve the ISO problem either. Engine is installed as a virtual machine on VMware and manages two KVM hosts (also a fresh install). I replaced the certificates for the test, but it didn't help and I went back to the old configuration. I keep getting a certificate error when running the test, even though I added it to the browser. I tested on different browsers. "Connection to ovirt-imageio service has failed. Ensure that ovirt-engine certificate is registered as a valid CA in the browser." Can I get help here?

Need advice before building a new oVirt Environment
by gbigras＠telesat.com 08 Nov '24

08 Nov '24

My question will be down below but before that here is some background info: I currently have a functioning oVirt env (v4.5.7) with two self-hosted nodes (hand-me-down servers) and shared storage (TrueNAS server) with three data domains: one for the EngineVM (iSCSI), one for the VMs (iSCSI) and one for ISO files (NFS). The powers that be, want to move away from TrueNAS and hand-me-downs and have new servers and a new NAS appliance (most likely NetApp). They are the ones who did not want to spend the money on new gear but now they have changed their minds. I wish that I could have started my oVirt env on the new equipment. This new equipment will take at best 2 months to arrive. In the meantime, I have to create various VMs in my existing environment. Once my new gear arrives, what is the recommended approach: 1 - Start from scratch with a new datacenter/cluster env? Can I migrate VMs from one DC to another? The docs seem to say no. I'm guessing, I would have to export first, then import. 2 - Can my new equipment be part of the same DC but a different cluster? I was thinking that option #2 is the right approach. I could start with storage (ie: new NetApp) as part of the new cluster. Once that is part of the cluster, I can add hosts then finally migrate VMs. What say you? thank you in advance.

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

This devroom will host presentations that focus on topics of shared interest, such as KVM; libvirt; shared storage; virtualized networking; cloud security; clustering and high availability; interfacing with multiple hypervisors; hyperconverged deployments; and scaling across hundreds or thousands of servers. Presentations in this devroom will be aimed at developers working on these platforms who are looking to collaborate and improve shared infrastructure or solve common problems. We seek topics that encourage dialog between projects and continued work post-FOSDEM.

With respect to oVirt hosts and the hosted-engine, what are the pros and cons of using just IPv4, or just IPv6, or using both?
