About oVirt’s future
by Yedidyah Bar David 23 Nov '22

23 Nov '22

Hi all, Red Hat Virtualization (RHV) recently entered maintenance phase[1], and the RHV development team is gradually shifting its efforts over to other projects. We are still around, subscribed to the mailing lists, answering questions and help as needed. There is a strong trend in the industry towards containers and microservices, and Red Hat's part of that is OpenShift. People that want to use OpenShift and still need virtualization, until they transition their workloads to run in containers, would best be served by using OpenShift Virtualization. Following this, if you are an oVirt user, you might want to try OKD Virtualization [2], the Community Distribution of Kubernetes that powers Red Hat OpenShift, and Forklift [3], a migration tool that facilitates the transition of VM workloads from oVirt to OKD Virtualization. We worked hard over the last year or so on making sure the oVirt project will be able to sustain development even without much involvement from us - including moving most of the infrastructure from private systems that were funded by/for oVirt/RHV, elsewhere - code review from Gerrit to GitHub, and CI (Continuous Integration) from jenkins to GitHub/Copr/CentOS CBS. We see lots of activity in the community both trying and using oVirt, and helping each other, which is great! We also see some work done on basing oVirt on Rocky/Alma Linux, which is also great! We’ll be happy to help with this, where our specific expertise is needed. Ultimately, the future of oVirt lies in the hands of the community. If you, as a community member, use and like oVirt, and want to see it thrive, now is the best time to help with this! In particular, we welcome long-time, active members of this list to join the list moderation team. If you want to help with this, please contact me directly, or email ovirt-users at ovirt.org. I am posting this message to both lists - users and devel, separately - deliberately not cross-posting. If you are subscribed to both, and feel like replying, please choose the list that best matches the content of your reply. Thanks! :-) Best regards, [1] https://access.redhat.com/support/policy/updates/rhev [2] https://docs.okd.io/latest/virt/about-virt.html [3] https://www.konveyor.io/tools/forklift/ -- Didi

Hi Users, I have got a Problem: Vmstore is full with 97 % (3TB). I want to cleanup and have delete 2 vms with round 500 GB harddiskspace together on a single node. In gluster .shard/.remove_me are 6 files but after 6 h I got no new free diskspace. What I am doing wrong? Can I force the cleanup? I have ovirt 4.3.9 running. Br Marcel

Problem trying to deploy oVirt 4.5 hosted engine on Ceph iSCSI
by fsayd＠derecho.uncu.edu.ar 21 Nov '22

21 Nov '22

Hello: I am following Sandro's guide to deploy hosted engine using Ceph and iSCSI. I have deployed a 3-node Ceph cluster and set up the iSCSI gateway. I am using Rocky Linux 8.6 as host OS. These are the steps I have taken: Install Rocky Linux on the hosts. Deploy Ceph Quincy cluster using cephadm and containers. Install and configure ceph-iscsi from repos pointed out in Sandro's guide. Provision an iSCSI target and lun in gwcli. Configure dnf and repos for RedHat derivatives (https://www.ovirt.org/download/install_on_rhel.html) Configure ovirt 4.5 repo: dnf install -y centos-release-ovirt45 Reset and configure virt module: dnf module reset virt dnf module enable virt:rhel dnf distro-sync --nobest Install hosted apliance: dnf install ovirt-engine-appliance Install hosted-engine-setup dnf install ovirt-hosted-engine-setup At this point I get an error about hosted-engine-setup conflicting with ansible-core: # dnf install ovirt-hosted-engine-setup Failed to set locale, defaulting to C.UTF-8 Last metadata expiration check: 2:37:30 ago on Thu Nov 17 09:16:13 2022. Error: Problem: package ovirt-hosted-engine-setup-2.6.6-1.el8.noarch requires ansible-core >= 2.12, but none of the providers can be installed - package ovirt-hosted-engine-setup-2.6.6-1.el8.noarch conflicts with ansible-core >= 2.13 provided by ansible-core-2.13.3-1.el8.x86_64 - cannot install the best candidate for the job (try to add '--allowerasing' to command line to replace conflicting packages or '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages) Can you help me with this error? I am not sure about the order of the steps and the configured repos. Thanks in advance

Hosts force fencing after engine upgrade 4.3->4.4
by ernest.beinrohr＠axonpro.sk 21 Nov '22

21 Nov '22

Hi, I was in the process of upgrading 4.3 to 4.4. First I upgraded the engine and the hosts are still 4.3. The engine has started fencing my hosts as there has been 1 (one) connection problem to VDSM on the host. I Basically, the engine at some random time connects to vdsm, this crashes (didnt on e4.3) and after a few seconds the engine issues a fencing and all my VMs are taken down .... This happend with multiple hosts at random times. Can this be attributed to the unmatched hosts? Or should I consider an engine restore to 4.3? Engine ovirt-engine-4.4.10.7-1.el8.noarch: 2022-11-21 10:40:05,788+01 ERROR [org.ovirt.engine.core.vdsbroker.irsbroker.UploadStreamVDSCommand] (EE-ManagedScheduledExecutorService-engineScheduledThreadPool-Thread-16) [258de39e] Command 'UploadStreamVDSCommand(HostName = galador, UploadStreamVDSCommandParameters:{hostId='146456e8-02fd-4 ce0-9140-13032d9a52ca'})' execution failed: java.net.SocketException: Connection reset by peer (Write failed) HOST vdsm-4.30.46-1.el7.x86_64: 2022-11-21 10:40:05,785+0100 ERROR (Reactor thread) [vds.dispatcher] uncaptured python exception, closing channel <yajsonrpc.betterAsyncore.Dispatcher connected ('::ffff:10.10.80.100', 37772, 0, 0) at 0x7f73cba72710> (<type 'exceptions.TypeError'>:object of type 'NoneType' has no len() [/usr>

activate incremental backup on disk with ansible ovirt_disk module
by Nathanaël Blanchet 20 Nov '22

20 Nov '22

Hello, I've struggled for hours with enabling incremental backup on disk level with the ansible ovirt.ovirt.ovirt_disk module: - name: modify incremental backup state ovirt.ovirt.ovirt_disk: auth: "{{ ovirt_auth }}" id: "{{disk_id}}" backup: "incremental" But the disk never gets into an incremental state. What's the matter? PS: I know I can do the same with curl, but this is not what I want.
