我正在尝试在几台运行 Ubuntu 的虚拟机之间设置一个私有网络。对于此特定配置，我需要启用 eth1 - eth9。出于某种原因，eth1 可以正常打开（使用ifconfig eth1 up，但不适用于ifup eth1），但找不到 eth2-9。我去年能够做到这一点，但我忘记了设置的一些细节。
这是我的/etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface

iface lo inet loopback
# The primary network interface

我还安装了 isc-dhcp-server 并进行了编辑/etc/default/isc-dhcp-server以包含所有接口，如下所示：

我觉得很奇怪，eth1 可以工作，但其他的都不行——就像我说的，我以前也让它工作过（我记得使用相同的文件）。我在想是不是我漏掉了某个步骤，或者把这些文件放在了错误的目录中？
任何帮助都将非常感激。
