一、Nova组件概述
计算节点通过Nova Computer进行虚拟机创建，通过libvirt调用kvm创建虚拟机，nova之间通信通过rabbitMQ队列进行通信。
Nova位于Openstack架构的中心，其他服务或者组件（比如Glance、Cinder、Neutron等）对它提供支持，另外它本身的架构也比较复杂。
作用：
- Nova是OpenStack最核心的服务模块，负责管理和维护云计算环境的计算资源，负责整个云环境虚拟机生命周期的管理。
- Nova是OpenStack的计算服务，负责维护和管理的网络和存储，提供计算服务。
二、Nova组建操作
1、安全组相关操作

三、nova和其他组件交互操作
1、云主机卷挂载操作
