CentOS下kvm安装配置,CentOSkvm安装配置

根据个人实际情况修改文件，在此只是记录本人的工作环境；

1，安装系统需要的文件

yum -y install kvm kmod-kvm kvm-qemu-img

yum -y install bridge-utils tunctl

2，创建ifcf-br0文件vi /etc/sysconfig/network-scripts/ifcfg-br0

DEVICE=br0

HWADDR=F4:6D:04:40:90:47

TYPE=Bridge

IPADDR=192.168.1.22

NETMASK=255.255.255.0

ONBOOT=yes

NM_CONTROLLED=no

3，修改系统网卡配置文件ifcfg-eth3 ，修改内容如下：

DEVICE=eth3

HWADDR=F4:6D:04:40:90:47

ONBOOT=yes

BRIDGE=br0

NM_CONTROLLED=no

4,修改/etc/qemu-ifup

#!/bin/sh

set -x

bridge=br0

interface=$1

/sbin/ip link set $interface up

/usr/sbin/brctl addif $bridge $interface

5,修改/etc/qemu-ifdown

#!/bin/sh

set -x

bridge=br0

interface=$1

ifconfig $interface down

tunctl -d $interface

6,/etc/init.d/network restart

如果配置正常，连通设备后

1,创建虚拟器

qemu-img create -f qcow2 linux-6-x86_64.img 10G

2，安装虚拟机

/usr/libexec/qemu-kvm –m 1024 -hda ./linux-6-x86_64.img -localtime -net nic,macaddr=DE:AD:BE:EF:F0:01 -net tap -cdrom /opt/release/centos-6-x86_64-CD.iso -boot d -vnc :1

3，运行虚拟机

/usr/libexec/qemu-kvm -m 1024 -hda ./linux-6-x86_64.img -localtime -net nic,macaddr=DE:AD:BE:EF:F0:01 -net tap -vnc :1
