I could be wrong but i believe you need to push libvirt / qemu to a newer release on your hosts to enable the feature. This may be a 4.3 only thing though.
I have 4.4 and currently on host: qemu-kvm-4.1.0-23.el8.1.x86_64 libvirt-daemon-5.6.0-10.el8.x86_64
Too old, you need RHEL 8.2, best RHEL 8.2.1 nightly build. Using ovirt-release-master.rpm: dnf install http://resources.ovirt.org/pub/yum-repo/ovirt-release-master.rpm You should get newer enough libvirt and qemu on CentOS 8.1, but it is not tested with incremental backup. It should work on Fedora 30 host, but Fedora 30 is EOL now. New enough libvirt and qemu are available in Fedora 31 and 32 (using virt-preview repo), but installing oVirt there is a challenge and I don't think anyone tested it yet.
Possibly needed sw pieces will be only in 4.4.1?
4.4.1 will include important fixes and new features in oVirt, but it will not help with libvirt and qemu. Nir
