I'm working in a group that maintains a large oVirt setup based on 4.4.1 which works very well. We are afraid of upgrading and prefer setting up a new installation and gradually enlist the hosts one by one into the new installation. We have tried 4.4.10 and 4.5.1 - 4.5.4 based on CentOS Stream 8, Rocky 8, Alma Linux 9.1 with various problems. Worst was the problem that the rpm db ended up in a catch-22 state. Using Alma Linux 9.1 and current oVirt 4.5.4 seems promising as no rpm problems are present after installation. We have only one nuisance left which we have seen in all installation attempts we have made since 4.4.10. When rebooting a host it takes 10 minutes before it's activated again. In 4.4.1 the hosts are activated a few seconds after they have booted up. I have found the following in the engine log: 2023-01-24 23:01:57,564+01 INFO [org.ovirt.engine.core.bll.SshHostRebootCommand] (EE-ManagedThreadFactory-engine-Thread-1513) [2bb08d20] Waiting 600 seconds, for server to finish reboot process. Our ansible playbooks for deployment times out and we could increase the timeout but how come that this 10 minutes delay has been introduced? Does a config file exist where this timeout can be set to a lower value? BR Peter H.

Create VM with Python SDK

by Alan G

Hi, Trying to create a VM while attaching an existing disk. I can create the VM then attach the disk with an additional call, but I thought it should be possible to do it in one hit? My code is vm = vms_service.add( types.Vm( name='alma8.7', description='AlmaLinux 8.7 CIS Packer image', cluster=types.Cluster( name='Default', ), type=types.VmType('server'), template=types.Template( name='Blank', ), disk_attachments=[types.DiskAttachment( disk=types.Disk(id = "0532e728-a1fb-4ff8-a4f3-0702fc876fce"), bootable=True, active=True, interface=types.DiskInterface.VIRTIO, )] ), ) This request returns no error but the disk isn't actually attached to the created VM.

VDSM Host command Get Host Capabilities failed: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

by Vasudev.ippili＠broadcom.com

We have a situation where nodes are left in Unassigned state. SSL certificate was expired and even after cert update the nodes are not coming out of Unassigned state. Its not even going in maintenance mode as there are VMs on it (although they are not responding right now). Anyway we can remove the node from HE and add it back?

Hello: I am following Sandro's blog post to configure oVirt with Ceph as storage domain (https://blogs.ovirt.org/2021/07/using-ceph-only-storage-for-ovirt-datacen...). I need to setup cinderlib but the referenced link is dead: https://ovirt.org/documentation/installing_ovirt_as_a_self-hosted_engine_... I can't find any instructions about cinder/ceph in ovirt docs. Any help? Thanks

Setting up hyperconverged engine with gluster storage

Hello, I'm setting up a new oVirt environment version 4.5 and want to use the hyperconverged setup on gluster storage.
