红帽全球峰会10.4. shelving 一个实例
如果您有一个不使用的实例，则 shelving 很有用，但您不想删除。当您 shelve 实例时，您可以保留实例数据和资源分配，但清除实例内存。根据云配置，Mandlved 实例会立即移到 SHELVED_OFFLOADED 状态，或延迟时间后。当 SHELVED_OFFLOADED 时，实例数据和资源分配会被删除。
当您 shelve 实例时，计算服务会生成一个快照镜像，该镜像捕获实例的状态，并以以下格式为镜像分配一个名称： < instance>-shelved。当实例被取消删除时，会删除此快照镜像。
如果您不再需要 shelved 实例，您可以将其删除。您可以一次Mandlve 多个实例。
流程
检索您要 shelve 的实例或实例的名称或 ID：
$ openstack server listherlve 实例或实例：
$ openstack server shelve <instance> [<instance> ...]将 &
lt;instance> 替换为您要 shelve 的实例的名称或 ID。您可以根据需要为 shelve 指定多个实例。验证实例是否已是 shelved ：
$ openstack server listshelved 实例的状态为
SHELVED_OFFLOADED。
