正在启动 dhcpd：

我有一个使用 KVM 的 Centos 6 虚拟机。

当我启动 DHCPd 服务“service dhcpd start”时，我得到以下信息：

Starting dhcpd:       [FAILED]

当我执行“dhcpd”时，我得到以下信息：

这是我的 dhcpd.conf：

我该如何修复此问题？我想在 eth1 上配置 DHCPd。

有人能帮助我并提供给我确切的详细信息和命令吗？

我建议你读一下dhcp.conf 手册页。

dhcpd 无法启动的原因在您的问题中明确说明 - 您没有告诉它在任何接口上监听。

要像您所说的那样监听 eth1，您至少需要类似于 dhcpd.conf 中的以下子句：

subnet 10.0.0.5 netmask 255.255.255.0 {
   range 10.0.0.6 10.0.0.254;
}

但是您需要对其进行调整以适合您的 eth1 的配置方式 - 我对掩码和所需范围做出了假设。

预安装的 dhcpd.conf 文件可能有很多预设，只需取消注释即可运行。它可能也注释得很好。
