平时一直玩rhel/centos/oel系列的操作，玩虚拟化也是采这一类系统,kvm在rhel6系列操作系统支持比较好，本文采用采用oel6.3操作系统，网上所有文章都说kvm比xen简单，我怎么感觉kvm比较复杂，可能是它的工具太多了吧，所以决定开始记录kvm的学习过程。
1.操作系统安装
本文采用oel6.3x64操作系统，也可以采用rhel/centos6.x。
(1)修改内核模式为兼容内核启动
(2)关闭selinux，重启后生效
(3)关闭防火墙

|
chkconfig ip6tables offchkconfig iptables off |
(4)重启
|

|
# reboot |
2.虚拟化环境配置
(1)查看是否支持虚拟机
说明1:半虚拟化是不能运行与安装kvm虚拟机的。
|
1
|
#egrep '(vmx|svm)' --color=always /proc/cpuinfo |
(2)配置yum环境
oel6.3已经配置好源，只需要开启即可。
(3)安装kvm软件包
|
1
|
#yum -y install kvm python-virtinst libvirt tunctl bridge-utils virt-manager qemu-kvm-tools virt-viewer virt-v2v |
过程略。
补充安装kvm虚拟化一些管理工具包

|
#yum -y install libguestfs-tools |

3.查看虚拟化环境
(1)查看虚拟机环境
(2)查看kvm模块支持
(3)查看虚拟工具版本
4.手动配置虚拟网桥
(1)关闭networkmanager服务
(2)创建br0网桥

(3)关闭了networkmanager服务之后，才能通过servicenetworkrestart管理网络。
(4)查看网桥br0.
(4)查看网桥
到此kvm虚拟化环境安装完毕。
