新增作業系統 image 到 Glance

1. 導入 admin 環境變數。
   

   [root@kvm4 ~]# source keystonerc_admin 
   [root@kvm4 ~(keystone_admin)]#
   

2. 上傳作業系統 image，目前 glance 只接受 http，不支援 ftp。
   

   [root@kvm4 ~(keystone_admin)]# glance image-create \
   --name "minkvm" \
   --is-public True \
   --disk-format qcow2 \
   --container-format bare \
   --copy-from http://deyu.wang/minkvm.qcow2

3. 列出可用的 image，其狀態為存檔中。
   

   [root@kvm4 ~(keystone_admin)]# glance image-list
   +--------------------------------------+--------+-------------+------------------+-----------+--------+
   | ID                                   | Name   | Disk Format | Container Format | Size      | Status |

   +--------------------------------------+--------+-------------+------------------+-----------+--------+
   

4. 列出可用的 image minkvm 細部資訊。
   

   [root@kvm4 ~(keystone_admin)]# glance image-show minkvm
   +------------------+--------------------------------------+
   | Property         | Value                                |

   | checksum         | b01710b20d305795d3a834cd3e01d62b     |
   | container_format | bare                                 |
   | created_at       | 2014-01-24T19:31:49                  |
   | deleted          | False                                |
   | disk_format      | qcow2                                |
   | id               | 79e088a9-0d8c-40fc-b5d5-13865cc891d2 |
   | is_public        | True                                 |
   | min_disk         | 0                                    |
   | min_ram          | 0                                    |
   | name             | minkvm                               |
   | owner            | a57da7d8a5f944c9b6258d0d91b8dee2     |

   +------------------+--------------------------------------+
   

5. 經過一段時間，再列出 image minkvm，狀態已變為 active。
   

   [root@kvm4 ~(keystone_admin)]# glance image-list
   +--------------------------------------+--------+-------------+------------------+-----------+--------+
   | ID                                   | Name   | Disk Format | Container Format | Size      | Status |
   +--------------------------------------+--------+-------------+------------------+-----------+--------+
   | 79e088a9-0d8c-40fc-b5d5-13865cc891d2 | minkvm | qcow2       | bare             | 941756416 | active |
   +--------------------------------------+--------+-------------+------------------+-----------+--------+
