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
|
1
2
|
chkconfig ip6tables off
chkconfig iptables off
|
(4)重启
|
1
|
# 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
|
1
|
#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
