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 |
+--------------------------------------+-------------+-------------+------------------+----------+--------+
| b3f9088f-ca51-4a03-ab9a-66e9c4baacce | cirros      | qcow2       | bare             |  | active |
| b408a7da-7fff--8f17-9e48f34553ef | cirros-test | qcow2       | bare             |  | active |
+--------------------------------------+-------------+-------------+------------------+----------+--------+
