It has integrated container management, ability to leverage the k8s distributed architecture/infrastructure and to leverage k8s assets like exclusive CPU placements.
It currently lacks live-snapshot, live-storage-migration, memory overcommit management, passthrough of a very specific PCI device on a particular host, VM portal (OKD UI is more similar to Admin portal), thin-provisioning (of VMs on top of templates), hot (un)plug (disk/memory/NIC), high availability with VM leases, incremental backup, VDI features like template versions, sealing (virt-sysprep).So OKD is not feature complete replacement for oVirt yet.
So okd virtualization aims to be a replacement in the next years when all ovirt features will be achivied for kubvirt, that's why ovirt continue to be maintained for the moment, great new!
Openshift IPI being also maintained is a great new because bare metal okd installation is not as easy as ovirt is (even I know we need bare metal to consume okd virtualization). Can you confirm we can merge bare metal and virtualized core is hosts? Is nested virtualization available?
