环境：
manager： 192.168.122.10 4核8G LVM100G硬盘
nova1: 192.168.122.20 4核4G LVM100G硬盘
nova2： 192.168.122.21 4核4G LVM100G硬盘
虚拟公有IP池范围：192.168.122.50-192.168.122.150
本次采用kvm虚拟机部署，网络使用virio，这样网络效率会快很多。本博yum仓库是自己搭建在本地的ftp上的，时间服务器也是同步本机，本机同步阿里云服务器的，后端镜像也是自己做的对内核部分和软件部分进行了优化，制作后端盘重点XML文件中网卡一栏中Interface中千万不要保留mac address，常识问题我居然还是踩坑了。
首先我使用的我的后端盘进行复用做的这几个系统，之前系统盘是20G，所以首先是对我的磁盘进行扩容。
扩容思路：
热扩容镜像大小限制（虚拟实例正在运行，为了不关机选择热扩容）。
刷新分区大小。
扩容lvm 卷组大小。
扩容lv 逻辑卷大小。
刷新文件系统大小。
开始热扩容镜像大小。
