[ovirt-users] Cluster level 4.5

What version of libvirt is required for a host to be put in this cluster level? I am using CentOS 8.3 and cpu is Cascade Lake Server. It says that my host is only compatible with cluster version 4.2,4.3 and 4.4. I am doing a new install of Ovirt 4.4.5. I have tried to update libvirt version but have run into issues. Currently installed libvirt is libvirt-6.0.0-28.module_el8.3.0+555+a55c8938.x86_64. Don
