Hi Nir It was a fresh install of 2 VMs on top of VirtualBox with Rocky fully updated on both prior to oVirt installation. I installed it yesterday and followed the usual way of installing it: https://www.ovirt.org/download/alternate_downloads.html. Here are the oVirt packages that are installed on the hypervisor: ovirt-vmconsole-1.0.9-1.el8.noarch ovirt-ansible-collection-1.5.3-1.el8.noarch ovirt-openvswitch-ovn-2.11-1.el8.noarch ovirt-host-dependencies-4.4.7-1.el8.x86_64 ovirt-vmconsole-host-1.0.9-1.el8.noarch ovirt-openvswitch-ovn-host-2.11-1.el8.noarch ovirt-openvswitch-2.11-1.el8.noarch ovirt-provider-ovn-driver-1.2.33-1.el8.noarch ovirt-host-4.4.7-1.el8.x86_64 ovirt-imageio-client-2.2.0-1.el8.x86_64 python3-ovirt-setup-lib-1.3.2-1.el8.noarch python3-ovirt-engine-sdk4-4.4.13-1.el8.x86_64 ovirt-release44-4.4.7-1.el8.noarch ovirt-hosted-engine-ha-2.4.7-1.el8.noarch ovirt-hosted-engine-setup-2.5.2-1.el8.noarch ovirt-imageio-daemon-2.2.0-1.el8.x86_64 ovirt-python-openvswitch-2.11-1.el8.noarch ovirt-openvswitch-ovn-common-2.11-1.el8.noarch cockpit-ovirt-dashboard-0.15.0-1.el8.noarch ovirt-imageio-common-2.2.0-1.el8.x86_64 and repos: appstream Rocky Linux 8 - AppStream baseos Rocky Linux 8 - BaseOS extras Rocky Linux 8 - Extras ovirt-4.4 Latest oVirt 4.4 Release ovirt-4.4-advanced-virtualization Advanced Virtualization packages for x86_64 ovirt-4.4-centos-ceph-pacific Ceph packages for x86_64 ovirt-4.4-centos-gluster8 CentOS-8 - Gluster 8 ovirt-4.4-centos-nfv-openvswitch CentOS-8 - NFV OpenvSwitch ovirt-4.4-centos-opstools CentOS-8 - OpsTools - collectd ovirt-4.4-centos-ovirt44 CentOS-8 - oVirt 4.4 ovirt-4.4-copr:copr.fedorainfracloud.org:mdbarroso:ovsdbapp Copr repo for ovsdbapp owned by mdbarroso ovirt-4.4-copr:copr.fedorainfracloud.org:sac:gluster-ansible Copr repo for gluster-ansible owned by sac ovirt-4.4-copr:copr.fedorainfracloud.org:sbonazzo:EL8_collection Copr repo for EL8_collection owned by sbonazzo ovirt-4.4-epel Extra Packages for Enterprise Linux 8 - x86_64 ovirt-4.4-openstack-train OpenStack Train Repository ovirt-4.4-virtio-win-latest virtio-win builds roughly matching what will be shipped in # yum list installed qemu-kvm Installed Packages qemu-kvm.x86_64 15:4.2.0-48.module+el8.4.0+534+4680a14e @AppStream # yum list installed libvirt Installed Packages libvirt.x86_64 7.0.0-14.1.el8 @ovirt-4.4-advanced-virtualization I didn't do anything out of ordinary - as a matter of fact i wanted to make an experiment to see if I can move from CentOS8 to Rocky by doing clean installation before doing it for "real" on bare metal nodes. Thank you. Kind regards, Branimir
