本文介绍了liNUX实战：OpenStack制作CentOS6.7镜像，希望对您有用。如果有疑问，可以联系我们。

1.下载镜像
直接拜访官方镜像地址下载,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6.7,在isos目录下下载x86_64的Minimal镜像.

2.创建虚拟机
首先必要创建一个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 qcow2CentOS-6.7.qcow2 20G
Formatting 'centos-6.7.qcow2',fmt=qcow2 size=21474836480 encryption=offcluster_size=65536 lazy_refcounts=off refcount_bits=16
快速创建并启动虚拟机：
root@UKVM-img:/var/lib/libvirt/images# virt-install --virt-type kvm --namecentos-6.7 --ram 1024 --diskcentos-6.7.qcow2,format=qcow2 --networknetwork=default --graphicsvnc,Listen=0.0.0.0 --noautoconsole --os-type=linux --os-variant=rhel6 --cdrom=CentOS-6.7-x86_64-minimal.iso

Starting install...
Creating domain... | 0 B 00:00:00
Domain installation still in progress. You can reconnect to
the console to complete the installation process.
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 or upgrade an existing system,继续选择语言,选择键盘格局,选择Basic Storage Devices,开启网络,设置主机名为默认,设置时区Asia/Shanghai,设置root暗码,选择“Create Custom Layout”,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,如图：

完成安装配置工作,末了点击右下角的reboot重启退出虚拟机.

4. 配置OS
安装好系统后,还必要进行配置才能作为glance镜像使用,启动虚拟机：
root@UKVM-img:~# virsh List --all
ID name State
----------------------------------------------------
- centos-6.7 shut off
- centos7.2.1511-L shut off
- centos72-L shut off

root@UKVM-img:~# virsh start centos-6.7
Domain centos-6.7 started

# The mirror system uses the connecting IP address of the clIEnt and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the clIEnt. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorList= does not work for you,as a fall back you can try the
# remarked out baseurl= line instead.
