在虚拟 ubuntu 14.04 服务器上设置两个网络接口的问题[关闭]

  • 772

我必须分配给 VM（ubuntu 14.04，使用 virt-manager 安装在虚拟环境中）。在 virt-manager 上我已经创建了 2 个这样的 vnetwork

这是分配了 2 个 vnet 的 VM

而接口文件是这样配置的

sudo nano /etc/network/interfaces

# The PUBLIC first network interface
auto eth0
iface eth0 inet static
        address 1.1.1.254
        netmask 255.255.255.0
        network 1.1.1.0
        broadcast 1.1.1.255
        gateway 1.1.1.1
        # dns-* options are implemented by the resolvconf package, if installed
        dns-nameservers 1.1.1.1
# The PRIVATE second network interface
auto eth1
iface eth0 inet static
        address 1.1.10.254
        netmask 255.255.255.0
        network 1.1.10.0
        broadcast 1.1.10.255
        gateway 1.1.10.1
        # dns-* options are implemented by the resolvconf package, if installed
        dns-nameservers 1.1.10.1

而命令 ifconfig -a 显示了所有界面

我还运行了 lshw -c network，界面结果为 disable

为什么 eth1 接口没有通过文件接收 IP 地址，而手动是？

server virt-manager

    哎呀，我太不专心了……这是错误

    auto eth1
iface eth0 inet static

    我错了 iface
