　　vzagent0@218.244.128.71's password:

　　!connect: No error

　　Connection to 218.244.128.71 closed.

　　这个问题一般是由于SVPS内部的ssh服务和vz相关服务有问题造成的

　　而SSH服务通常是和硬件节点的NAT模式绑定在一起的，所以就造成了一个ssh能连接的假象

　　但即便输入正确的密码，也会报告!connect: No error之类的错误

　　这个时候只要重启SVPS即可修复。

　　登陆到硬件节点，执行vzctl restart 1

　　等待几秒后，SVPS重启完成，再次测试连接，问题修复。
