[root@foundation15 ~]# scp /etc/cluster/fence_xvm.key root@172.25.15.10:/etc/cluster/


[root@foundation15 ~]# scp /etc/cluster/fence_xvm.key root@172.25.15.11:/etc/cluster/
key文件是通过dd指令生成的大小为512b的文件，只要每台机器该文件的大小一致，fence就能生效
主机要线安装fence
yum -y install fence*
service fence_virtd restart
chkconfig fence_virtd on
