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.

Enroll Certificate
by Денис Панкратьев 03 Jan '25

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?

oVirt and TPM

Did some one use TPM in oVirt ? I tried to active it but failed to use. The VM is configured to use an EFI secure boot. The VM (a RHEL 9.5 OS) see it, but I can’t communicate with it: $ dmesg | grep -i tpm [ 0.000000] efi: SMBIOS=0x7ddd5000 TPMFinalLog=0x7dfe7000 ACPI=0x7df7e000 ACPI 2.0=0x7df7e014 MEMATTR=0x7cbd9018 MOKvar=0x7dd82000 RNG=0x7df71018 TPMEventLog=0x7c544018 [ 0.018626] ACPI: TPM2 0x000000007DF76000 00004C (v04 BOCHS BXPC 00000001 BXPC 00000001) [ 0.018657] ACPI: Reserving TPM2 table memory at [mem 0x7df76000-0x7df7604b] [ 5.312318] systemd[1]: TPM2 PCR Machine ID Measurement was skipped because of an unmet condition check (ConditionPathExists=/sys/firmware/efi/efivars/StubPcrKernelImage-4a67b082-0a4c-41cf-b6c7-440b29bb8c4f). pcsc_scan fails to read it: $ sudo pcsc_scan -s -v PC/SC device scanner V 1.6.2 (c) 2001-2022, Ludovic Rousseau <ludovic.rousseau(a)free.fr> SCardEstablishContext: RPC transport error.

Curl error (7): Couldn't connect to server for https://mirrorlist.ovirt.org/mirrorlist-ovirt-4.5-el8
by eyup ustaoglu 29 Dec '24

Hello. I keep getting this error during the ovirt PREPARE VM phase. Is there a site where I can get the current repositories under /etc/yum.repos.d? Also, have ovirt updates stopped? Why are repo addresses that have been unreachable for a long time still in the ovirt node?

I am in the Prepare VM step in ovirt installation. and I keep getting the above error. Why is the unused repo address defined even though I downloaded the latest ovirt-node? Where can I find repo addresses for el8 that can be accessed for installation? Is ovirt a discontinued system?

I think you can onoy have one master. Have you tried just promoting a domain vs. trying to add a new one? Erik Sent from my iPad

Migrate from Centos8 to Centos9
by suporte＠logicworks.pt 19 Dec '24

19 Dec '24

Hi, I need to migrate from Centos8 to Centos9, engine+ 2 nodes, iSCSI storage, My idea is backup Engine on Centos8: engine-backup --scope=all --mode=backup --file=/root/backup Then install a new engine machine with Centos9 and restore: engine-backup --mode=restore --file=backup --log=backup_restore.log engine-setup Now Engine on Centos9 is controlling the 2 nodes on Centos8 Than, I migrate all VMs from node2 to node1. Install node2 with Centos9 Migrate all VMs from node1 to node2 Install node1 with Centos9 Do you think it will work? Thanks -- Jose Ferradeira http://www.logicworks.pt
