14.04 服务器 PXE 安装在“配置网络”页面失败

Question

尝试无人值守 PXE 安装，在此页面失败

Network autoconfiguration failed
Your network is probably not using the DHCP protocol. Alternatively,
the DHCP server may be slow or some network hardware is not working
properly.

我的 DHCP 服务器适用于 12.04 和所有其他 Linux 发行版，例如 RHEL 和 SLES。更重要的是，它pxelinux.0被获取，内核和 initrd 被下载并启动。所以我认为这应该是客户端问题而不是服务器问题。特别是14.04安装程序问题。

跳转到安装程序中的一个shell，发现ifconfig不可用。尝试过dhclient，它没有返回错误（返回代码也是 0），但仍然无法 ping PXE 或 DHCP 服务器。失败的错误ping是“网络无法访问”。tcpdump显示在 PXE 中的初始请求之后，DHCP 服务器上没有任何 DHCP 请求。

lspci 显示所有 NIC。

知道出了什么问题吗？

其他信息：

ip link 显示接口是 p1p1 但 /etc/network/interface 显示只配置了 eth0。

附加biosdevname=0到内核中的 PXE 默认文件中，即可解决此网络问题。原因可以在这个文档中找到：

参考：Nicnaming \xe2\x80\x93 用Biosdevname解决
