OpenStack单节点制作镜像

1、创建快照

已修改后的时刻为记录，进行制作镜像，选择要制作镜像的虚拟机，点击创建快照，在所弹出的对话框中输入所创建的镜像名称

生成了一个镜像，类型为Snapshot

2、保存镜像

查看镜像列表

[root@controller ~]# source /etc/keystone/admin-openrc.sh 
[root@controller ~]# 
[root@controller ~]# glance image-list
+--------------------------------------+-------------+-------------+------------------+----------+--------+
| ID                                   | Name        | Disk Format | Container Format | Size     | Status |
+--------------------------------------+-------------+-------------+------------------+----------+--------+
