[root@ovirt1 ~]# As you can see my CentOS7 - Updates is enabled. So far I have managed to upgrade 4.2.7 -> 4.2.8 -> 4.3.0 -> 4.3.1 There were some issues , but nothing related to the repos.

One cluster based on CentOS7 hosts, another based on ovirt-node-ng. While the second was successfully updated from 4.2.7 to 4.2.8, attempts to update hosts of the first one ends with: Error: Package: vdsm-4.20.46-1.el7.x86_64 (ovirt-4.2) Requires: libvirt-daemon-kvm >= 4.5.0-10.el7_6.3 Installed: libvirt-daemon-kvm-4.5.0-10.el7.x86_64 (@base) libvirt-daemon-kvm = 4.5.0-10.el7 Being a CentOS7 installation and not an ovirt-node-ng, I cannot follow the notice in : https://lists.ovirt.org/archives/list/users@ovirt.org/message/AJUBXAIGXVD... The only way to have libvirt-daemon-kvm release 4-5-0.10_6.4 (and not 6.3) is to enable CentOS Updates repo. Looking at host-deploy log looks fine, but It's safe to enable that repo ? There is another, safest method to update these hosts to the latest version of 4.2 ? Thanks in advance -- Roberto Nunin --
