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。
