1、创建网桥的目的是为了让KVM虚拟机连接到这个网桥,从而使虚拟机可以和物理网络通信
2、当然,安装完kvm后,会自动建立一个网桥virbr0,这个网桥应该是nat模式
一、DHCP网桥创建
vim /etc/network/interfaces
这是interfaces配置文件的内容:
# 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 auto lo iface lo inet loopback # The primary network interface auto eth0 iface eth0 inet dhcp 物理网卡也为DHCP auto br100 iface br100 inet dhcp 配置br100网桥为DHCP bridge_ports eth0 配置br100建立在物理网卡eth0上 bridge_stp off bridge_fd
创建完成后,重启网络
静态网桥
vim /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 auto lo iface lo inet loopback # The primary network interface auto eth0 iface eth0 inet static address 192.168.89.3 gateway 192.168.89.2 netmask 255.255.255.0 network 192.168.89.0 broadcast 192.168.89.255 auto br100 iface br100 inet static bridge_ports eth0 bridge_stp off bridge_fd 0 bridge_maxwait 0 address 192.168.89.3 network 192.168.89.0 netmask 255.255.255.0 broadcast 192.168.89.255 gateway 192.168.89.2
创建完成后,重启网络
