11.3.2. Creating a vGPU flavor for instances
After you deploy the overcloud with GPU-enabled Compute nodes, you can create a custom flavor that your cloud users can use to launch instances for GPU workloads.
Procedure
Create an NVIDIA GPU flavor. For example:
(overcloud) [stack@virtlab-director2 ~]$ 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 | +----------------------------+--------------------------------------+
Assign a vGPU resource to the flavor that you created. You can assign only one vGPU for each instance.
(overcloud) [stack@virtlab-director2 ~]$ openstack flavor set m1.small-gpu --property "resources:VGPU=1" (overcloud) [stack@virtlab-director2 ~]$ 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 | +----------------------------+--------------------------------------+
