Use-Cases
| No of Masters Ready or Running | Expected | Actual |

| 3 Masters | Ingress Created with VIP IP and ping to VIP should work | VIP is working |
| 2 Masters | Ingress Created with VIP IP and ping to VIP should work | VIP is working |
| 1 Master | Ingress Created with VIP IP and ping to VIP should work | VIP is not working, Kubectl is not responding |
I have Created a RKE2 HA Cluster with kube-vip and the cluster is working fine only when at least 2 masters are in Running, but I want to test a use case where only 1 master is available the VIP should be able to ping and any ingress created with VIP address should work.
In my case when 2 masters are down I'm facing an issue with kube-vip-ds pod, when i check the logs using crictl command I'm getting the below error can someone suggest to me how to reslove this issue.
