openstack instance change storage dir

在云计算openstack中以为新建的虚拟机都存放在/var/lib/nova/instances中，在新建虚拟机时内存当然不够用，所以可以将nova转移到新的存储位置

以下操作只在计算节点上进行

一：停止虚拟机
   查看虚拟机：
   $nova list
   停止将要迁移的虚拟机
   $nova stop INSTANCEID
二：数据迁移
   $cp -r /var/lib/nova/instances/  /openstack/
三：修改虚拟机存储路径

#vi /etc/nova/nova.conf

#实例路径
    instances_path=/openstack/instances
    #nova的目录
    state_path=/openstack/instances

四：重启compute服务和启动虚拟机

#systemctl restart openstack-nova-compute.service

启动虚拟机： #nova start INSTANCEID
