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

image

(2)关闭selinux,重启后生效

image

(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

image

(2)配置yum环境

OEL6.3已经配置好源,只需要开启即可。

image

(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

image

(2)查看kvm模块支持

image

(3)查看虚拟工具版本

4.手动配置虚拟网桥

(1)关闭networkmanager服务

image

(2)创建br0网桥
