kvm虚拟化学习笔记(一)之kvm虚拟化环境安装

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



(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

[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。



(4)查看网桥br0.



(4)查看网桥



到此kvm虚拟化环境安装完毕。
