      Description of problem:
      OpenShift Virtualization 4.20 has a warning:

      PodDisruptionBudgetAtLimit
      Nov 3, 2025, 9:04 AM
      The pod disruption budget is at the minimum disruptions allowed level. The number of current healthy pods is equal to the desired healthy pods.
      
      $ oc get csv
      NAME                                       DISPLAY                    VERSION   REPLACES                                   PHASE

      How reproducible:

      
      

      Steps to Reproduce:

      1. Install OpenShift Virtualization 4.20 on OpenShift 4.20
      2.
      3.
      

      Expected results: No warning or at least configuration to make it possible to get rid of warnings I can't control.

      Additional Info:
      It looks like the poddisruptionbudget was added to the SSP operator a few months ago:
      https://github.com/kubevirt/ssp-operator/commit/5d59423ed0480758f4c832283f1259b11bf65582

      The minimum availability is hard coded.
      https://github.com/kubevirt/ssp-operator/commit/5d59423ed0480758f4c832283f1259b11bf65582#diff-a9ef4e14d927674e4e507b28d660a27cfaf7d8610c79c40a5706f9f4db8a78d5R404

      So even if I try to add a jsonpatch annotation to reduce the number of replicas it does nothing other than add an additional informational item that I have an unsafe configuration.

          ssp.kubevirt.io/jsonpatch: |-
            [
              {
                "op": "replace",
                "path": "/spec/templateValidator",
                "value": {"replicas": 1}
              }
            ]
