KVM安装

Posted 2020-10-14

Ubuntu16.4

首先安装KVM所需要的包

 

sudo apt-get install qemu-kvm qemu-system libvirt-bin virt-manager bridge-utils vlan

说明:

1.qemu-kvm 和 qemu-system 是KVM和QEMU的核心包，提供CPU，内存，和IO虚拟化功能！

2.libvirt-bin 就是libvirt，用于管理KVM等Hypervisor。

3.virt-manager是KVM的图形化管理工具。

4.bridge-utils 和 vlan 主要是用做网络虚拟化的。另外，KVM的网络虚拟化的实现是基于linux-bridge 和VLAN。

安装图形化界面（Ubuntu默认是不安装图形界面的，请手工安装）

sudo apt-get install xinit
sudo apt-get install gdm
sudo apt-get install kubuntu-desktop

 apt 会默认到ubuntu官网下载，所以我们这里需要配置国内源(ubuntu16.04)，下载速度较快。

vi /etc/apt/source.list
