I have some oVirt clusters, in various config.

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/AJUBXAIGXVD5U5O2VYHO3BONVROSGWNW/

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
