Use the Ceph official mirror: * Pacific el8 - https://download.ceph.com/rpm-pacific/el8/x86_64/ * Reef el9 - https://download.ceph.com/rpm-reef/el9/x86_64/ Good luck, k

I am using the following, but am getting the following error and am unable to proceed. I don't have the IP address 192.168.1.195 set in anything, but do I need to set something somewhere? Also, I can connect to the internet and name resolution is possible with a different IP.

I would not begin from oVirt Node ISO (ovirt-node-ng-installer-4.5.5-2023113015.el9.iso), but from a new clean CentOS Stream 9 install. Cause as you see the ovirt-node-ng images are quite outdated. And then try to execute the installation. On 2/06/2025 07:17, d_hashima@sagaidc.co.jp wrote:

I have completed the installation of oVirt Engine, but I am unable to add a host due to the following error. The host and oVirt Engine gateways have the same address. The currently selected CPU type for the cluster is Secure Intel Cascadelake Server Family, and the host CPU model and vendor are Intel(R) Xeon(R) Gold 6242 CPU @ 2.80GHz. Error: Host has no default route. The host CPU does not match the Cluster CPU Type and is running in a degraded mode. It is missing the following CPU flags: vmx, model_Cascadelake-Server-noTSX. Please update the host CPU microcode or change the Cluster CPU Type.

Many chances that you meet ce same error I met a few month ago... The issue may not come from any CPU misconfiguration, to be sure you should have a look to /var/log/ovirt-engine/engine.log. If you find any error lines about ovn, you will easily resolve your issue following this: https://www.mail-archive.com/users@ovirt.org/msg73109.html Let us know how it works for you!

Is there a way to delete hosts that are displayed as Unassigned from ovirt?

The following error occurred and the host could not be added. The default gateway is the same as the ovirt environment. Error content: Host has no default route.

That error is fixed in https://github.com/oVirt/vdsm/commit/49eaf70c5a14eb00e85eac5f91ac36f010a9a32... You can apply the patch manually. But we need to make a new release asap :) Jean-Louis On 11/06/2025 03:20, d_hashima@sagaidc.co.jp wrote:

I have tried fresh install of CentOS Stream 9 with the standard repo and the nightly repo that is recommended and continue to get the error referencing "mirrorlist.centos.org" (which no longer exists). I've verified none of the yum.repo.d files contain mirrorlist.centos.org, so I don't know where this is coming from. I've been trying to install the self-hosted engine for the past 2 days and run into this error no matter what repos I use and have tried Rocky Linux 9 and AlmaLinux 9 as well. I'd really prefer not to use CentOS or the nightly build repo in order to have a more stable system, but even following these recommendations the installation errors out referencing mirrorlist.centos.org. Nothing I do to install the self-hosted engine works and I'm getting very frustrated, wondering if anyone is actually able to get it installed. Is there some straight forward, tested, working instructions somewhere, because following the oVirt documentation page doesn't work.
