13.KVM安装之网桥

安装必须的几个库和软件(最好下载一个163的yum源,速度快点)

$ yum -y install kvm python-virtinst libvirt tunctl bridge-utils virt-manager qemu-kvm-tools virt-viewer virt-v2v

$ /sbin/lsmod | grep kvm查看kvm模块

$ service libvirtd restart              启动libvirtd

$ chkconfig libvirtd on设置虚拟机服务开机启动

$ cd /etc/sysconfig/network-scripts/去备份之前网卡信息

$ touch /etc/sysconfig/network-scripts/ifcfg-br0   创建网桥配置文件

$ service NetworkManager stop    #停止网卡守护进程

$ chkconfig NetworkManager off#关闭网络管理,让桥接生效

1. service NetworkManager stop  //这个关闭掉就行  
2. 停止 NetworkManager 守护进程：                             [确定]  

配置网卡和网桥

#vim ifcfg-br0编辑网桥内容(为了防止断网可以写好脚本和配置文件直接替换后重启网卡)

DEVICE=br0

TYPE=Bridge

BOOTPROTO=static

IPV6INIT=no

ONBOOT=yes

IPADDR=192.168.10.10

NETMASK=255.255.255.0

GATEWAY=192.168.10.1

DNS1=1.2.4.8

DNS2=114.114.114.114

#把宿主机物理网卡添加到网桥(vim /etc/sysconfig/network-scripts/ifcfg-p2p1)

DEVICE=p2p1

TYPE=Ethernet

ONBOOT=yes

IPV6INIT=no

BOOTPROTO=none

BRIDGE=br0

###配置网桥脚本###

#!/bin/bash

mkdir -p /home/bak

cp /etc/sysconfig/network-scripts/ifcfg*  /home/bak

yes | mv ifcfg* /etc/sysconfig/network-scripts

sleep 2

service network restart

#连上后杀掉脚本进程,连不上恢复之前配置

sleep 500

yes | mv /home/bak/ifcfg* /etc/sysconfig/network-scripts
