在CoreOS-libvirt安装中，kube-addons.service失败
我有以下问题安装和供应我的Kubernetes基于CoreOS-libvirt的群集。
当我login主节点时，我看到以下内容：
ssh core@192.168.10.1 Last login: Thu Dec 10 17:19:21 2015 from 192.168.10.254 CoreOS alpha (884.0.0) Update Strategy: No Reboots Failed Units: 1 kube-addons.service 试图debugging它，我运行并收到以下内容：

我的etcd版本是：
etcd --version etcd version 0.4.9
但是我也有一个etcd2：
etcd2 --version etcd Version: 2.2.2 Git SHA: b4bddf6 Go Version: go1.4.3 Go OS/Arch: linux/amd64
而目前第二个正在运行：
ps aux | grep etcd etcd 731 0.5 8.4 329788 42436 ? Ssl 16:40 0:16 /usr/bin/etcd2 root 874 0.4 7.4 59876 37804 ? Ssl 17:19 0:02 /opt/kubernetes/bin/kube-apiserver --address=0.0.0.0 --port=8080 --etcd-servers=http://127.0.0.1:2379 --kubelet-port=10250 --service-cluster-ip-range=10.11.0.0/16 core 953 0.0 0.1 6740 876 pts/0 S+ 17:27 0:00 grep --colour=auto etcd
是什么导致了这个问题，我该如何解决呢？
谢谢。
相关的日志行是：
/opt/kubernetes/addons/skydns-svc.yaml": error validating data: found invalid field portalIP for v1.ServiceSpec; if you choose to ignore these errors, turn validation off with --validate=false
你应该找出什么是无效的IP或设置标志忽略。
