问问 buyvm的kvm主机联网问题。。

事情是这样的安装好debian的时候是可以上网的也可以update，安装了之后，就没有管了。。后来我登录了一下ssh，想wget一个东西，，然后就报错了。。说 找不到hostname，然后我执行 apt-get update 不行了。错误提示如下：


W: Failed to fetch http://ftp.us.debian.org/debian/dists/squeeze/main/i18n/Translation-en_US.gz Could not resolve 'ftp.us.debian.org'

然后发了个TK过去问。。客服回复了一段话 我也不知道是什么意思。。顺带求翻译一下。。感谢。。

回复内容：

You need to replace the missing entries in /etc/resolv.conf that networkmanager *insists* on removing, this is why you should remove network manager and always manually configure networking.



求帮助 求解答。。真心感谢。。
