network out of sync on CentOS9

[kandadeepak]

Currently using the oVirt version 4.5.6 on redhat 8.9 operating system

oVirt Version:4.5.6-1.el8
OS Version : CentOS Stream release 9
ovsdb-server (Open vSwitch) 2.17.10
vdsm - vdsm-4.50.5.1-1.el9.x86_64

Issue

While adding the Centos Stream 9 based oVirt Node into manager network goes to out of sync where as customized(Prebuild oVirt node) works without any out of sync.

When adding the Centos 9 base node into oVirt manager the gateway/dns getting flushed and Network's Configuration differ from DC.

To reproduce

Deploy new centos 9 node and steps for package and then add the node to manager.

[root@node01 ~]# dnf -y install centos-release-ovirt45
[root@node01 ~]# dnf -y install qemu-kvm libvirt virt-install vdsm cockpit
[root@node01 ~]# systemctl enable --now libvirtd cockpit.socket

Expected behavior

Not out of sync network error message should be populated.

Your screenshot is unreadable.
But most likely this is caused by newer libnl version.

Fixed in oVirt/vdsm@49eaf70

When I tried with oVirt manager(Redhat 9) and oVirt node(CentOS 9) on the VDSM shows the following error and screenshot

Do you have any workaround or fix in near future?
