kvm虚拟化学习笔记(一)之kvm虚拟化环境安装

最近访客

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

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，  我用的是workstation 安装centos6.3 所以还需要把centos6.3的虚拟化功能打开，

修改centos.vmx文件加入如下字段：“

nce.enable = "TRUE" hypervisor.cpuid.v0 = "FALSE" featMask.vm.hv.capable ="Min:1" vhv.enable = "TRUE"

1	#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

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

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55

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

1 2 3 4

[root@node1~]#cd  /etc/sysconfig/network-scripts/ [root@node1network-scripts]#cp ifcfg-eth0 ifcfg-br0 [root@node1network-scripts]# [root@node1network-scripts]#

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28

[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。
