      Description

      The node does not have kata runtime installed yet it is assigned the kata-oc role indicating to the user that all nodes are capable of providing kata runtime to the pods.

      Steps to reproduce

      1. installed the sandbox container operator from the image.
      apiVersion: operators.coreos.com/v1alpha1
      kind: CatalogSource
      metadata:
        name:  katacatalog
        namespace: openshift-marketplace
      spec:
        sourceType: grpc
        image: quay.io/openshift_sandboxed_containers/openshift-sandboxed-containers-operator-catalog:1.3.1-3
        publisher: Red Hat
        updateStrategy:
          registryPoll:
            interval: 10m0s

      Subscription YAML

      apiVersion: operators.coreos.com/v1alpha1
      kind: Subscription
      metadata:
        labels:
          operators.coreos.com/sandboxed-containers-operator.openshift-sandboxed-containers-op: ""
        name: sandboxed-containers-operator
        namespace: openshift-sandboxed-containers-operator
      spec:
        channel: stable-1.3
        name: sandboxed-containers-operator
        source: katacatalog
        sourceNamespace: openshift-marketplace

      2.  Create kataconfig after operator is installed successfully

      apiVersion: kataconfiguration.openshift.io/v1
      kind: KataConfig
      metadata:
        generation: 2
        name: kataconfig
      spec:
        checkNodeEligibility: false
        kataConfigPoolSelector: null
        kataMonitorImage: registry-proxy.engineering.redhat.com/rh-osbs/openshift-sandboxed-containers-operator-monitor:1.3.0
        logLevel: debug
        kataConfigPoolSelector:
          matchExpressions:
            - values:
                - worker-0
                - worker-1
              operator: In
              key: kubernetes.io/hostname

      Expected result

      The node should not have been assigned kata-oc role as the kata runtime is not installed on it.

      Actual result

      The node is assigned kata-oc role.

      Impact

      The user could run into scenario where the pod is attempted be scheduled to run using kata runtime class on the node that does not have runtime installed.
