　　security groyps
　　Security groups--> are sets of IP filter rules() that ,define networking access,are applied to
all instances within a project
　　default security group denies all incoming
traffic and allows only outgoing traffic to your instance
　　common use case is to edit the
default security group to permit SSH access and ICMP access, so that users can log into and
ping instances.
　　Example,create a security group:

　　
　　
　　云硬盘类型定义了云硬盘的规格参数. 通常为云硬盘映射一组后端驱动器的存储容量. 例如:"性能"."SSD"."备份",等.
　　
　　Example:
　　nova --debug list or keystone --debug user-list;
　　(关于OpenStack every core project client tools)
