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。

稳了!魔兽国服回归的3条重磅消息!官宣时间再确认!
昨天有一位朋友在大神群里分享,自己亚服账号被封号之后居然弹出了国服的封号信息对话框。
这里面让他访问的是一个国服的战网网址,com.cn和后面的zh都非常明白地表明这就是国服战网。
而他在复制这个网址并且进行登录之后,确实是网易的网址,也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情,因为以前都没有出现这样的情况,现在突然提示跳转到国服战网的网址,是不是说明了简体中文客户端已经开始进行更新了呢?
