基础环境：
192.168.1.67 super67
硬件cpu需要支持：Intel VT-x 技术
本实验使用虚拟机VMware Workstation上的虚拟机
操作系统：CentOS6.5
物理机确保开启cpu虚拟化技术（进入bois设置）
VMware Workstation的设置：
检查cpu是否支持硬件虚拟化技术（Intel->vmx AMD->svm）
[root@super67 ~]# grep -E "(vmx|svm)" /proc/cpuinfo --color
检查是否支持64位：
[root@super67 ~]# grep lm /proc/cpuinfo --color
检查内核是否编译kvm模块：
[root@super67 ~]# grep -i "kvm" /boot/config-2.6.32-431.el6.x86_64
CONFIG_KVM_CLOCK=y
CONFIG_KVM_GUEST=y
CONFIG_HAVE_KVM=y
CONFIG_HAVE_KVM_IRQCHIP=y
CONFIG_HAVE_KVM_EVENTFD=y
CONFIG_KVM_APIC_ARCHITECTURE=y
CONFIG_HAVE_KVM_CPU_RELAX_INTERCEPT=y
CONFIG_KVM=m
CONFIG_KVM_INTEL=m
CONFIG_KVM_AMD=m
从内核中装载kvm：
[root@super67 ~]# lsmod |grep kvm
[root@super67 ~]# modprobe kvm
[root@super67 ~]# modprobe kvm_intel
[root@super67 ~]# lsmod |grep kvm
kvm_intel 54285 0
kvm 333172 1 kvm_intel
安装kvm及一些管理工具：
[root@super67 ~]# yum install -y kvm virt-manager libvirt qemu-kvm qemu-kvm-tools -y
启动管理API：
[root@super67 ~]# /etc/init.d/libvirtd start
Starting libvirtd daemon: [ OK ]
[root@super67 ~]# chkconfig libvirtd on
建立桥接设备，然后把接口添加进来，让kvm虚拟机可以上网：
[root@super67 ~]# yum install -y bridge-utils
修改eth0配置：
[root@super67 network-scripts]# cat ifcfg-eth0
DEVICE=eth0
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=no
BOOTPROTO=none
IPV6INIT=no
USERCTL=no
HWADDR=00:0c:29:8d:5c:df
BRIDGE="br0"
修改桥配置：
[root@super67 network-scripts]# cat ifcfg-br0
DEVICE="br0"
TYPE="Bridge"
ONBOOT=yes
NM_CONTROLLED=no
BOOTPROTO=none
IPADDR=192.168.1.67
NETMASK=255.255.255.0
GATEWAY=192.168.1.1
DNS1=114.114.114.114
IPV6INIT=no
USERCTL=no
HWADDR=00:0c:29:8d:5c:df
DNS2=8.8.8.8
重启网络：
[root@super67 ~]# /etc/init.d/network restart
[root@super67 ~]# ifconfig br0
br0 Link encap:Ethernet HWaddr 00:0C:29:8D:5C:DF

查看桥接信息：
[root@super67 ~]# brctl show
bridge name bridge id STP enabled interfaces
br0 8000.000c298d5cdf no eth0
virbr0 8000.52540015e279 yes virbr0-nic
使用图形化管理界面管理：
[root@super67 ~]# virt-manager
