After failed upgrade from 4.5.1 to 4.5.3, upgrades do not show up anymore
by Gianluca Amato 07 Dec '22

07 Dec '22

Hi all, I recently tried to upgrade an oVirt node from 4.5.1 to 4.5.3. The upgrade failed (I have no idea idea why... how can I access the installation logs?). The node is still working fine running the old 4.5.1 release, but now the oVirt web console says that it is up to date and it does not let me retry the upgrade. However, I am still on version 4.5.1, as witnessed by the result of "nodectl info": ---- bootloader: default: ovirt-node-ng-4.5.1-0.20220623.0 (4.18.0-394.el8.x86_64) entries: ovirt-node-ng-4.5.1-0.20220623.0 (4.18.0-394.el8.x86_64): index: 0 kernel: /boot//ovirt-node-ng-4.5.1-0.20220623.0+1/vmlinuz-4.18.0-394.el8.x86_64 args: crashkernel=auto resume=/dev/mapper/onn_ovirt--clai1-swap rd.lvm.lv=onn_ovirt-clai1/ovirt-node-ng-4.5.1-0.20220623.0+1 rd.lvm.lv=onn_ovirt-clai1/swap rhgb quiet boot=UUID=9d44cf2a-38bb-477d-b542-4bfc30463d1f rootflags=discard img.bootid=ovirt-node-ng-4.5.1-0.20220623.0+1 intel_iommu=on modprobe.blacklist=nouveau transparent_hugepage=never hugepagesz=1G hugepages=256 default_hugepagesz=1G root: /dev/onn_ovirt-clai1/ovirt-node-ng-4.5.1-0.20220623.0+1 initrd: /boot//ovirt-node-ng-4.5.1-0.20220623.0+1/initramfs-4.18.0-394.el8.x86_64.img title: ovirt-node-ng-4.5.1-0.20220623.0 (4.18.0-394.el8.x86_64) blsid: ovirt-node-ng-4.5.1-0.20220623.0+1-4.18.0-394.el8.x86_64 layers: ovirt-node-ng-4.5.1-0.20220623.0: ovirt-node-ng-4.5.1-0.20220623.0+1 current_layer: ovirt-node-ng-4.5.1-0.20220623.0+1 ------ Comparing the situation with other hosts in the same data center, it seems that the problem is that the package ovirt-node-ng-image-update-placeholder is not installed anymore, hence "dnf upgrade" has nothing to do. My idea was to manually download and install the 4.5.1 version of ovirt-node-ng-image-update-placeholder and attempt installation again. Is it a correct way to proceed ? Thanks for any help. --gianluca amato

vdsmd crashes with sigsegv
by ovirt＠kirschke.de 24 Nov '22

24 Nov '22

Hello, since upgrade from ovirt 4.3 to 4.5., I encounter problems with one host. vdsmd permanently crashes after a while and it tells me, a segmentation violation is the cause. As result, it becomes unresponsive to ovirt-engine. Environment: rocky linux 8.6, up to date ovirt 4.5.2; One datacenter, compatibility level 4.7 The ovirt engine is on a seperate vm outside of ovirt. Any one else had that problem, or a has a tipp, where to start investigating the problem? Thanks and best regards Steffen

what happens to vms when a host shutdowns?
by Nathanaël Blanchet 15 Nov '22

15 Nov '22

Hi, We are installing UPS powerchute client on hypervisors. What is the default vms behaviour of running vms when an hypervisor is ordered to shutdown: do the vms live migrate or do they shutdown properly (even the restart on an other host because of HA) ? -- Nathanaël Blanchet Supervision réseau SIRE 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

Blog Post - Using Ceph Only Storage For oVirt Datacenter by Sandro Bonazzola – Wednesday 14 July 2021
by Matthew J Black 10 Nov '22

10 Nov '22

Hi All, In the above mentioned blog post (https://blogs.ovirt.org/2021/07/using-ceph-only-storage-for-ovirt-datacente…) in mentions the line: "Follow oVirt documentation for setting up Cinderlib" with a link to this URL: https://ovirt.org/documentation/installing_ovirt_as_a_self-hosted_engine_us… This link is broken/obsolete/no longer available, so my question(s) is/are: Where can I obtain this information? Is there a new URL? Are these instructions no-longer required with the new oVirt v4.5.X? Can someone who has these instructions post/email them, please? Thanks in advance Dulux-Oz

Creating new system
by vkasabiev＠gmail.com 04 Nov '22

04 Nov '22

Hello, can you pls help me with creating my oVirt system. I installed Centos 7 on one VM and on one physical server. I succesfully configured my VM for oVirtEngie and I can access to web interface. Now I want to configure my physical server to use it as virtualization server(kvm01). My VM has 2 disks, one for system and one for ISO images. My phisycal server also has 2 disks(actually 4 but in 2 Raid1). One for system and one for virtualization storage. Its the second time I try to install everything properly, 1st time I had some issues and decided to reinstall everything. 1st time I successfully added my kvm01 to my ovirtengine, but I couldnt create any VM because I had error with my Data Center, that had status uninitialized, and it seems like I cant initialize it because I have no domain. I'm already confused and decided to ask forum for a correct answer and advices. What shell I do first? I havent added kvm01 to my ovirtEngine yet.

VNC console connection fails [ovirt 4.5.3.1-1.el8]
by andre.liebe＠gematik.de 02 Nov '22

02 Nov '22

Hello list, is there anybody else out there having problems to connect to a vm console via vnc or is it just me? We are running ovirt-engine 4.5.3.1-1.el8 on up to date ovirt-nodes. I can connect to every virtual machine by spice, but am unable to connect via vnc due to a tls handshake error. Remote-viever just shows "Failed to complete handshake Error in the pull function" (on windows and linux clients). Wireshark tls handshake capture looks supicious to me, server hello message is just 182 bytes long and doesn't coantain a server certificate. Is this normal? sincerely André

Nightly build to stable

Hi, I've installed the Version 4.5.4-0.2.master.20221007083550.gitb24d914c24.el8 few days before (since the stable not working at the time) Is there any way to make this installation following the stable updates if the 4.5.4 became stable?
