MaaS = ubuntu 15 节点 = ubuntu 14
使用 maas：1.7.6+bzr3376-0ubuntu2~15.04.1 http://pastebin.com/4nCxtMg2
节点在 PXE 启动幕安装请求后发生故障。来自节点的云初始化信息： http://pastebin.com/TPJaNmHT

我确实担心的具体细节

通过“nslookup high-pin”查找主机名不起作用，但“nslookup high-pin.maas”可以。resolv.conf 不包含搜索域。这对于 curtain 安装来说正常吗？
nslookup、apt-get upgrade、apt-get update、ping、全部工作和路由。
马斯事件日志：
