平時一直玩RHEL/CentOS/OEL系列的操做，玩虛擬化也是採這一類系統,kvm在RHEL6系列操做系統支持比較好，本文采用採用OEL6.3操做系統，網上全部文章都說KVM比xen簡單，我怎麼感受kvm比較複雜，多是它的工具太多了吧，因此決定開始記錄KVM的學習過程。node

1.操做系統安裝

本文采用OEL6.3X64操做系統，也能夠採用RHEL/CentOS6.x。

(1)修改內核模式爲兼容內核啓動

(2)關閉selinux，重啓後生效

(3)關閉防火牆

chkconfig ip6tables off
chkconfig iptables off

(4)重啓

# reboot

2.虛擬化環境配置

(1)查看是否支持虛擬機

說明1:半虛擬化是不能運行與安裝KVM虛擬機的。

#egrep '(vmx|svm)' --color=always /proc/cpuinfo

(2)配置yum環境

OEL6.3已經配置好源，只須要開啓便可。

(3)安裝kvm軟件包

#yum -y install kvm python-virtinst libvirt tunctl bridge-utils virt-manager qemu-kvm-tools virt-viewer virt-v2v

過程略。

補充安裝kvm虛擬化一些管理工具包

#yum -y install libguestfs-tools

3.查看虛擬化環境

(1)查看虛擬機環境

(2)查看kvm模塊支持

(3)查看虛擬工具版本

4.手動配置虛擬網橋

(1)關閉networkmanager服務

(2)建立br0網橋

[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)關閉了networkmanager服務以後，才能經過servicenetworkrestart管理網絡。

(4)查看網橋br0.

(4)查看網橋

到此kvm虛擬化環境安裝完畢。
