Hi Folks, Am a complete newbie with oVirt and am researching how to install in an ESXi server, the idea is to create a VM that runs the oVirt host and hosted engine with a virtual NFS server, I found the following but am not able to get the hoste engine VM to deploy, I am not seeing anything leaping out at me from the log file and was hoping that others may have experiences they can share? https://jorgedelacruz.uk/2021/07/26/ovirt-detailed-guide-on-how-to-deploy... am also using https://www.ovirt.org/documentation/installing_ovirt_as_a_self-hosted_eng... TIA Mike

Re: Self-hosted engine 4.5.0 deployment fails

by John

I would run the deploy again, wait until the engine is up and then from the server you are deploying the engine on # virsh list obtain the virtual machine number from the above command, in the example below we assume the number is 1 # virsh console 1 login as root wait for all packages to finish updating: tail -f /var/log/dnf.rpm.log then: # dnf downgrade postgresql-jdbc once that's done the deployment of the engine should get past the [ INFO ] TASK [ovirt.ovirt.engine_setup : Check if Engine health page is up] step.

I need the deploy script to wait for fixing network configuration manually in oVirt 4.3.10

by lars.stolpe＠bvg.de

Hi, i'm planing to upgrade our production environment from oVirt 4.3 to 4.4. So i do need a fresh oVirt 4.3 installation to test the procedure before doing it in production. The command line deploy script can't handle network interfaces correctly. If i use either a single NIC oder a bond (active/passive) i get the error message "The selected network interface is not valid". If i predefine the management bridge to a running state, the deploy process goes on, but fails to activate the added host and removes the already running engine vm. The deploy process fails to synchronize the existing working network configuration with the engine configuration. I can already log in to the engine GUI and see, that the bridge "ovirtmgmt" needs to be assigned to the bonding IF, but i'm not fast enough to do so, because the deployment process ist already shutting down and erasing the vm. I do see the following ways to succeed: 1. make the depoyment process accept the given interfaces (maybe ignore errors) 2. make the deploy process wait for me to take necessary actions before checking the engine Do anyone know, how to achieve this? All i need is a running engine on hosted_storage... any other issues i can fix later. Another idea is to use one of the destined hosts as a bare metal engine, add hosts, backup the engine and use that backup for a hosted engine restore deploy, since the deploy script asks to wait after local vm is ready, but only if i do a recovery deploy. Any suggestions?

Changing the Cluster Compatibility Version in hyperconverged environment

by lexxthefox＠gmail.com

Hi! I'm sorry if it is a noob question but it is very important for me. We are researching oVirt in our company and hope to use existing environment where there's no SAN/NAS solution. Just a bunch of servers. We were able to set up a hyperconverged installation with oVirt 4.4 a while ago and now I'm resuming research and trying to upgrade it to 4.5. I was able to upgrade HE and Hosts. What's left is to upgrade Cluster Compatibility Version from 4.5 to 4.7. I don't seem to find a way to do it as when I try to Edit cluster I get this error: "Cluster Compatibility Version". Upgrade Guide on https://www.ovirt.org/documentation/upgrade_guide/ does not have entries for hyperconverged set up. So I don't know where to look for information on this topic. Is it possible to achieve my goal at all? Can "frozen" Cluster Compatibility Version cause problems in the long run? I can rebuild the whole setup now when it is still being reviewed and planed. But if we start using it actively it won't be possible. I'm afraid that this could be a show-stopper in the long run. Thanks in advance!

New Ovirt installation on existing Ovirt

by yevhen.kyrylchenko＠gmail.com

Hi! I have a strange idea - I try to create a small Ovirt test lab on my existing Ovirt infrastructure. I have two real Ovirt hosts: host01 - 192.168.1.10/24, GW 192.168.1.1 host02 - 192.168.1.11/24, GW 192.168.1.1 I created VM on which I want to install new Ovirt instance: v_host01 - 192.168.1.100, checked Pass-Through Host CPU. During deployment hosted engine on v_host01 (lets say v_he - 192.168.1.110), Ovirt creates temporary bridge with random IP and hosted engine VM can comunicate through that bridge. After successful deployment this HE VM has assigned static IP 192.168.1.110. And now communication is possible only between v_host01 and v_he... I can't reach network from v_he further than v_host01 and can't reach v_he from hosts other than v_host01. Seems than bridge on v_host01, created during deployment doesn't want to forward traffik... Do you have any ideas what should I check? Regards!

Regenerate DWH ovirt_engine_history

by Diego Ercolani

Hello to all and happy new year. My question is "simple". I need to "reset" the ovirt_engine_history database. I tried to use: engine-setup --reconfigure-optional-components after removing: - ovirt_engine_history - set to "False" OVESETUP_DWH_CORE/enable=bool:True OVESETUP_GRAFANA_CORE/enable=bool:True in /etc/ovirt-engine-setup.conf.d/20-setup-ovirt-post.conf (obviously all in "Global Maintenance") currently I have a system where I have an initialized ovirt_engine_history but no engine is writing in it. I tried to follow (in some manner): https://www.ovirt.org/documentation/data_warehouse_guide/ In the ovirt engine's log there is no exception... so I cannot address the issue. I need help to reinitialize the db... I don't need the history.. only from now on. Thank you for your help but no one is

cluster level - features

by marek

hi, do you have tips where can i find information about new features in cluster levels? i found only https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.4/... there is only information "there are new features" hard way i tried check https://www.ovirt.org/release/4.5.0/ and found https://bugzilla.redhat.com/show_bug.cgi?id=2021545 - Detecting if scratch disks can be extended automatically - Detecting if host support disk format conversion - Maybe for using qcow2 format by default to enable incremental backup by https://bugzilla.redhat.com/show_bug.cgi?id=2033185 - e1000e is there some "central" place ?
