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

[ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Check engine VM health] this cuz Jboos web page not working "Service Unavailable The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later." I open console to VM engine and... disk dm-6 and dm-3 was corrupted - LOL - must fix by xfs_repair. But after restart hosted-engne.service wont start. ● ovirt-engine.service - oVirt Engine Loaded: loaded (/usr/lib/systemd/system/ovirt-engine.service; enabled; vendor preset: disabled) Active: failed (Result: exit-code) since Mon 2022-10-31 15:35:30 CET; 4min 11s ago Process: 1469 ExecStart=/usr/share/ovirt-engine/services/ovirt-engine/ovirt-engine.py --redirect-output --systemd=notify $EXTRA_ARGS start (code=exited, status=1/FAILURE) Main PID: 1469 (code=exited, status=1/FAILURE) Oct 31 15:35:23 ovirt systemd[1]: Starting oVirt Engine...

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

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?

[4.4.7] The latest guest agent needs to be installed and running on the guest
by Christoph Timm 28 Oct '22

28 Oct '22

Hi list, I have upgraded my oVirt from 4.4.4 to 4.4.7 and notice that some VMs have issues to report the performance information via the guest agent. I see the following message on the VMs: The latest guest agent needs to be installed and running on the guest The qemu-guest agent is installed on VMs (the VM OS is CentOS 8). Any advice how to troubleshoot this? I can see the stats will be presented in the GUI, if I migrate the VM to a different host. Best regards Christoph
