You should set dnsPolicy: ClusterFirstWithHostNet too, the xds_clusters of envoyproxy used service name for looking up control plane:

          "cluster": {
            "@type": "type.googleapis.com/envoy.config.cluster.v3.Cluster",
            "connectTimeout": "10s",
            "loadAssignment": {
              "clusterName": "xds_cluster",
              "endpoints": [
                {
                  "lbEndpoints": [
                    {
                      "endpoint": {
                        "address": {
                          "socketAddress": {
                            "address": "envoy-gateway",
                            "portValue": 18000
                          }
                        }
                      },
                      "loadBalancingWeight": 1
                    }
                  ],
                  "loadBalancingWeight": 1
                }
              ]

When you are using hostNetwork, we need to set dnsPolicy to ClusterFirstWithHostNet too.

Since we have supported deployment/svc mergepatch, I think we need to remove hostnetwork support on Envoyproxy API or have a more complete implementation for it.

Any thoughts on it @arkodg ?
