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 off
chkconfig 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。

#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

#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

kvm虚拟化学习笔记(一)之kvm虚拟化环境安装的步骤

(2)查看kvm模块支持

kvm虚拟化学习笔记(一)之kvm虚拟化环境安装的步骤

(3)查看虚拟工具版本

kvm虚拟化学习笔记(一)之kvm虚拟化环境安装的步骤

4.手动配置虚拟网桥

(1)关闭networkmanager服务

kvm虚拟化学习笔记(一)之kvm虚拟化环境安装的步骤

(2)创建br0网桥

[root@node1~]#cd /etc/sysconfig/network-scripts/
[root@node1network-scripts]#cp ifcfg-eth0 ifcfg-br0
[root@node1network-scripts]#
[root@node1network-scripts]#
[root@node1network-scripts]#vi ifcfg-eth0
device="eth0"
bootproto=static
nm_controlled="no"
onboot=yes
type="ethernet"
bridge="br0"
uuid="99dde4d3-94f1-4293-b8a8-b10255d5b8be"
hwaddr=00:0c:29:47:41:8c
ipaddr=192.168.233.130
prefix=24
gateway=192.168.233.2
dns1=192.168.233.2
defroute=yes
ipv4_failure_fatal=yes
ipv6init=no
name="systemeth0"
[root@node1network-scripts]#
[root@node1network-scripts]#vi ifcfg-br0
device="br0"
bootproto=static
onboot=yes
type="bridge"
hwaddr=00:0c:29:47:41:8c
ipaddr=192.168.233.130
prefix=24
gateway=192.168.233.2
dns1=192.168.233.2

(3)关闭了networkmanager服务之后,才能通过servicenetworkrestart管理网络。
