When KVM installing windows, F8 key is not enable, so we need press ctrl + F8 instead.
安装准备
首先检查CPU是否支持安装KVM：英特尔VT或AMD-V处理器才支持安装虚拟机，可用命令查看：
$ egrep -o '(vmx|svm)' /proc/cpuinfo
输出下面的信息说明该CPU支持安装KVM：
vmx
vmx
安装KVM
(1) 安装软件包
sudo apt-get install qemu-kvm libvirt-bin virt-manager bridge-utils qemu-system
sudo apt-get install kvm qemu
sudo apt-get install virtinst python-libvirt virt-viewer virt-manager
sudo apt-get install bridge-utils
其中：virt-manager为GUI管理窗口，bridge-utils:用于网络桥接。
(2) 安装测试
执行下面的命令看KVM是否安装成功：
kvm -ok
输出信息：
INFO: /dev/kvm exists
KVM acceleration can be used
如果提示信息为：
INFO: KVM (vmx) is disabled by your B
IOS(KVM [vmx]被你的BIOS禁用)
HINT: Enter your BIOS setup and enable Virtualization Technology (VT)
则需要进入的BIOS设置界面，启用虚拟化技术[VT]，设置步骤为：
进入BIOS后，选择ADVANCED，然后至 PROCESSOR CONFIGURATION进去找到，
INTEL (R) VIRTUALIZATION TECHNOLOGY ，设置成ENABLE，保存退出 。
验证KVM内核是否加载成功：
lsmod | grep kvm
输出为：
kvm_intel 47162 0
kvm 317577 1 kvm_intel
若KVM内核没加载执行下面命令加载：
$ sudo modprobe kvm
$sudo modprobe kvm-intel ( or kvm-amd )
证实KVM正常运行
virsh -c qemu:///system list
将输出：
Id Name State
如果提示你没权限操作，则需要将当前操作账户添加进libvirtd组，命令为：
sudo usermod -G libvirtd -a fdc
(4) 启动KVMGUI
virt-manager
(5) 确认libvirtld后台服务是否启动
sudo service libvirt-bin status
如下是修改完成后的网卡配置文件，具体配置步骤请往下看。

Following is config network adapter steps:
1. check interface information.

sudo cp /etc/network/interfaces /etc/network/interfaces.bak1
cd /etc/network
sudo vim interfaces
2. After opening the configure file, Following is the contents:
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface

gateway 103.11.246.129
# dns-* options are implemented by the resolvconf package, if installed
dns-nameservers 103.11.244.2
3. Change into below file
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
iface eth0 inet manual
# The primary network interface

使用命令virt-manager进入虚拟机配置的图形界面进行配置。
注意安装的时候硬盘要选择scsi格式的，不要用ide格式的，否则会很慢。架构也要使用qemu不要使用kvm。
