Host deploy failure: Configure OVN for oVirt

Good day, I am running into a problem during host deploy via the oVirt engine GUI since upgrading to ovirt-engine-4.5.5-1.el8. The "Configure OVN for oVirt" task seem to fail when trying to run the vdsm-tool ovn-config command. Host deploy used to work fine when the engine was on version 4.5.4. Anyone that can guide me on the right path to get past this issue? Does not seem to be a new problem - https://lists.ovirt.org/archives/list/users@ovirt.org/thread/IDLGSBQFX35EHH… Log extract: 2024-02-01 14:48:19 SAST - TASK [ovirt-provider-ovn-driver : Configure OVN for oVirt] ********************* . . .

We use ovirt-engine 4.5.5-1.el8 and for us the following did the trick: 1. First you have to decide, if you need the ovn/ovs functionality. This is a cluster level decision! * If needed, you need to have a functional (You can test it) external network provider configured (Administration -> Providers -> External Network Provider) ?? As far as I know, a default "ovirt-provider-ovn" is already present in each installation * Then in the cluster option you choose the "Default Network Provider". If you don't need OVS/OVN, then select "No Default Provider", else select the one you need * If you change here anything, ovirt want you to reinstall all your hosts in this cluster! 2. Then, replace the ansible file in your ovirt-engine: * /usr/share/ovirt-engine/ansible-runner-service-project/project/roles/ovirt-provider-ovn-driver/tasks/configure.yml * The new version can be found here: https://github.com/oVirt/ovirt-engine/blob/master/packaging/ansible-runner-… as far as I can tell, only the last line (when statement) changes Probably, only ppl who don't need ovn/ovs had (Setting: "No Default Provider") had this problem. 1. Reinstall the hosts As always, know what you do, before you anything.

Hello! My ovirt host (4.5.5) certificate is about to expire (in 46 days, Jan 20, 2025). d.pankratiev@zabbix ~]$ echo | openssl s_client -servername ovirt1.gtc.local -connect XXX.XXX.XXX.XXX.XXX:9090 2>/dev/null | openssl x509 -noout -dates 2>/dev/null notBefore=Dec 22 05:27:04 2023 GMT notAfter=Jan 20 05:27:04 2025 GMT 1. I have migrated all VMs to another host 2. I put the host in maintenance mode (Managеment -> Maintenance) 3. Do enroll certificate (Installation -> Enroll Certificate) 4. Everything went successfully, without errors (Enrolling certificate for host ovirt1.gtc.local was completed successfully). But the certificate date did not change, still expire (after 46 days, Jan 20 2025). d.pankratiev@zabbix ~]$ echo | openssl s_client -servername ovirt1.gtc.local -connect XXX.XXX.XXX.XXX.XXX:9090 2>/dev/null | openssl x509 -noout -dates 2>/dev/null notBefore=Dec 22 05:27:04 2023 GMT notAfter=Jan 20 05:27:04 2025 GMT What did I do wrong? Is there anything else I need to do?
