Ubuntu16.04中安装KVM

基本的 Ubuntu 操作系统装好之后，安装 KVM 需要的包 。

1、在此之前先确认是否CPU支持虚拟化

 执行命令：   egrep -o '(vmx|svm)' /proc/cpuinfo

如何有返回值则说明支持，例如返回带有vmx的值

2、配置国内镜像源，否则会出现各种无法安装的问题(遇到很多稀奇古怪的问题)

现在用的是阿里源， cd  /etc/apt 修改sources.list文件中的内容

deb http: //mirrors .aliyun.com /ubuntu/ xenial main restricted universe multiverse
deb http: //mirrors .aliyun.com /ubuntu/ xenial-security main restricted universe multiverse
deb http: //mirrors .aliyun.com /ubuntu/ xenial-updates main restricted universe multiverse
deb http: //mirrors .aliyun.com /ubuntu/ xenial-backports main restricted universe multiverse
##测试版源
deb http: //mirrors .aliyun.com /ubuntu/ xenial-proposed main restricted universe multiverse
# 源码
deb-src http: //mirrors .aliyun.com /ubuntu/ xenial main restricted universe multiverse
deb-src http: //mirrors .aliyun.com /ubuntu/ xenial-security main restricted universe multiverse
deb-src http: //mirrors .aliyun.com /ubuntu/ xenial-updates main restricted universe multiverse
deb-src http: //mirrors .aliyun.com /ubuntu/ xenial-backports main restricted universe multiverse
##测试版源
deb-src http: //mirrors .aliyun.com /ubuntu/ xenial-proposed main restricted universe multiverse
# Canonical 合作伙伴和附加
deb http: //archive .canonical.com /ubuntu/ xenial partner
deb http: //extras .ubuntu.com /ubuntu/ xenial main

修改后sudo apt-get update

3、 安装KVM及相关依赖包

sudo apt-get install qemu-kvm
sudo apt-get install qemu
sudo apt-get install virt-manager
sudo apt-get install virt-viewer
sudo apt-get install libvirt-bin

sudo apt-get install bridge-utils

4、

 确认 Libvirtd 服务已经启动

# service libvirt-bin status

libvirt-bin start/running, process 1478

5、启动KVM验证

完成KVM安装
