KVM精简教程(二)：配置网卡桥接
1.安装网卡桥接的软件包：yum -y install bridge-utils tunctl
2.启用网络桥接
1)cd /etc/sysconfig/network-scripts/
#cp ifcfg-eth0 ifcfg-br0
2) 修改ifcfg-eth0
DEVICE=eth0
HWADDR=00:0C:29:D0:48:55
TYPE=Ethernet
UUID=ffdf9de0-75a3-4028-a83b-1e739c75b2bb
ONBOOT=yes
NM_CONTROLLED=no
BRIDGE=br0
3) 修改ifcfg-br0
DEVICE=br0
TYPE=Bridge
ONBOOT=yes
NM_CONTROLLED=no
BOOTPROTO=static
IPADDR=192.168.100.90
NETMASK=255.255.255.0
GATEWAY=192.168.100.1
DNS1=114.114.114.114
DNS2=8.8.8.8
4) 向文件/etc/sysctl.conf添加以下代码:
net.bridge.bridge-nf-call-ip6tables = 0
net.bridge.bridge-nf-call-iptables = 0
net.bridge.bridge-nf-call-arptables = 0
# sysctl –p
3.配置完成后重启操作系统
