Otherwise, your hosts are managing VMs as threads and containers as threads, side-by-side,
without awareness of conflict.
Ex: dockerd expects to manage its network for containers, and oVirt expects to manage a
network (bridge) for VMs. Docker will be expecting to have iptables work for it, and then
oVirt too! https://docs.docker.com/network/
You'll have to manage the conflicts yourself without KubeVirt.
