14.4. 为实例创建 vGPU 类别
要让您的云用户能够为 GPU 工作负载创建实例,您可以创建一个 GPU 类别来启动 vGPU 实例,并将 vGPU 资源分配给该类别。
先决条件
- 您已使用 GPU 设计的 Compute 节点配置和部署 overcloud。
流程
创建 NVIDIA GPU 类别,例如:
(overcloud)$ openstack flavor create --vcpus 6 \ --ram 8192 --disk 100 m1.small-gpu +----------------------------+--------------------------------------+ | Field | Value | +----------------------------+--------------------------------------+ | OS-FLV-DISABLED:disabled | False | | OS-FLV-EXT-DATA:ephemeral | 0 | | disk | 100 | | id | a27b14dd-c42d-4084-9b6a-225555876f68 | | name | m1.small-gpu | | os-flavor-access:is_public | True | | properties | | | ram | 8192 | | rxtx_factor | 1.0 | | swap | | | vcpus | 6 | +----------------------------+--------------------------------------+
为您创建的类别分配一个 vGPU 资源。您只能为每个实例分配一个 vGPU。
(overcloud)$ openstack flavor set m1.small-gpu \ --property "resources:VGPU=1" (overcloud)$ openstack flavor show m1.small-gpu +----------------------------+--------------------------------------+ | Field | Value | +----------------------------+--------------------------------------+ | OS-FLV-DISABLED:disabled | False | | OS-FLV-EXT-DATA:ephemeral | 0 | | access_project_ids | None | | disk | 100 | | id | a27b14dd-c42d-4084-9b6a-225555876f68 | | name | m1.small-gpu | | os-flavor-access:is_public | True | | properties | resources:VGPU='1' | | ram | 8192 | | rxtx_factor | 1.0 | | swap | | | vcpus | 6 | +----------------------------+--------------------------------------+
