Using KubeVirt should be fairly natural if you are used to working with Kubernetes.
The primary way of using KubeVirt is by working with the KubeVirt kinds in the Kubernetes API:
$ kubectl create -f vmi.yaml$ kubectl get vmis$ kubectl delete vmis testvmi
The following pages describe how to use and discover the API, manage, and access virtual machines.
KubeVirt does not come with a UI, it is only extending the Kuebrnetes API with virtualization functionality.
