rhel7 pxe 启动问题，dhcp 获取错误地址

我正在尝试设置一个新的 PXE 启动设置，一切似乎都正常，但是当它尝试获取 kickstart 文件时，它显示网络不可达

在此处输入图片描述

当我查看 dhcp 日志时，它说网络正在损坏

有什么想法吗？

答案1

您的环境中有多个 DHCP 服务器提供 IP 地址。

第一个 DHCP 服务器 IP = 192.168.5.111

第二个 DHCP 服务器 IP = 192.168.130.254（可能是 VMware DHCP 服务器）

请记住，第一个 DHCP 请求是 PXE DHCP 请求，第二个 DHCP 请求（启动内核/initrd 后）是普通的 DHCP 请求
