1.下载镜像
直接访问官方镜像地址下载，注意选择中国的镜像源，相对国外镜像下载速率比较快，进入后选择版本为7.2.1511，在isos目录下下载x86_64的Minimal镜像.
2.创建虚拟机
首先需要创建一个qcow2格式镜像文件，用于作为虚拟机的磁盘，大小20G.
root@UKVM-IMG:/var/lib/libvirt/images# qemu-img create -f qcow2centos7.2.1511-L.qcow2 20G
Formatting 'centos7.2.1511-L.qcow2',fmt=qcow2 size=21474836480encryption=off cluster_size=65536 lazy_refcounts=off refcount_bits=16
快速创建并启动虚拟机：
NAME=centos7.2.1511-L
ROOT_DISK=centos7.2.1511-L.qcow2
CDROM=/CentOS-7-x86_64-Minimal-1511.iso
sudo virt-install --virt-type kvm --name $NAME --ram 1024 \
--disk $ROOT_DISK,format=qcow2 \
--network network=default \
--graphics vnc,listen=0.0.0.0--noautoconsole \
--os-type=linux --os-variant=rhel7\
--cdrom=$CDROM
启动完成后，使用vnc client连接，可以直接使用virt-manager或者virt-viewer直接连接。
3. 安装OS
进入虚拟机控制台可以看到Centos的启动菜单，选择Install Centos 7，继续选择语言后将进入INSTALLIONSUMMARY，其中大多数配置默认即可，SOFTWARE SELECTION选择Minimal Install，INSTALLATION DESTINATION需要选择手动配置分区，只需要一个根分区即可，不需要swap分区，文件系统选择ext4，存储驱动选择Virtio Block Device，设置网络和初始Root密码，如图：
完成安装配置工作，最后点击右下角的reboot重启退出虚拟机.
4. 配置OS
安装好系统后，还需要进行配置才能作为glance镜像使用，启动虚拟机：
root@UKVM-IMG:/var/lib/libvirt/images# virsh list --all
Id Name State
----------------------------------------------------
- centos7.2.1511-L shut off
- centos72-L shut off
root@UKVM-IMG:/var/lib/libvirt/images# virsh start centos7.2.1511-L
Domain centos7.2.1511-L started
4.1 配置yum仓库

[root@localhost yum.repos.d]# ls
