Abnormal behavior on the reinstalled host

Hello everyone, I need help again with a host that I have reinstalled l and I don't understand why it doesn't work well. I have managed to get the host status to UP. But I can't migrate MV to this host. Yes, I can start a VM on this host and I can migrate it to another but it can't go back if you want. These are the errors I see: ID: 128 2024-03-19 20:34:56,809+01 WARN [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (EE-ManagedThreadFactory-engine-Thread-77603) [6ea57120-4e64-4b1d-a31f- 1072f69c478b] EVENT_ID: VM_MIGRATION_TRYING_RERUN(128), Failed to migrate VM srvlinux to Host ovirt51.mydomain due to an Error: Fatal error during migration. Trying to migrate to another Host. It also happens that I cannot access the noVNC console on this Host but the VM is running. It gives me this error: "Something went wrong, connection is closed" If I put the host in maintenance mode it does not activate again and gives an error: Operation Canceled Error while executing action: ovirt51.mydomain: Cannot activate Host. Host has no unique id. Resolved by reinstalling the host and checking to activate it. But it doesn't seem normal to me. Please does anyone know how to resolve these issues? Thank you.

Hello, hope, you are doing well. I try to install a new hosted engine on my environment to switch the storage this engine. I use following command to deploy the instance: hosted-engine --deploy --4 --ansible-extra-vars=he_offline_deployment=true Everything works fine, except the initialization of lockspace volume. Here I get: ``` [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Remove temporary entry in /etc/hosts for the local VM] [ INFO ] changed: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Set the name for add_host] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Fetch the value of HOST_KEY_CHECKING] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Get the username running the deploy] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Register the engine FQDN as a host] [ INFO ] changed: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Start ovirt-ha-broker service on the host] [ INFO ] changed: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Initialize lockspace volume] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Workaround for ovirt-ha-broker start failures] [ INFO ] changed: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Initialize lockspace volume] [ ERROR ] fatal: [localhost]: FAILED!

Unfortunately, the same error comes up. What can I do to solve this? Thanks very much balu

Recreate engine without backup
by Igor Filipovic 04 Apr '24

04 Apr '24

Hi all, I have a situation in which customer has deleted standalone engine completely (it was running on vmware), and all backups were saved on the same machine - so there is no backup available. Can someone suggest how to preserve virtual machines which are still running on kvm hosts, and recreate standalone engine to be able to manage existing kvm hosts and machines? What could be scenario for this? Thanks in advance and best regards! Igor

Server 2008R2 UEFI ISO Boot Problerm
by Clint Boggio 04 Apr '24

04 Apr '24

Greetings oVirt team I'm using "Version 4.5.7-0.master.20240327074810.git14bca0502d.el8 on CentOS Stream 9" I have occasion to restore a windows backup image for the purpose of data extraction. To accomplish this I need to boot off a Server 2008R2 ISO. The machine to be restored was UEFI based originally and so it is required to be UEFI for the restoration process. I seem to be having a problem with booting off of the ISO image in the required UEFI-based system. In pursuit of a solution I've read on some of the other forums about this same problem on other KVM-based platforms. Booting that same ISO after changing the VM to BIOS works flawlessly. In the articles and threads I've read there is mention of hyper-v services that load during the guest boot process that are causing the ISO boot to hang. Is it possible to disable (or is it even necessary to disable) "hv_time,hv_relaxed,hv_spinlocks=0x2000" in the "Custom Properties" section of the VM config ? If any of you have some insight into this problem and a possible solution I'd appreciate the feedback.
