Managing GPU-based flavors
GPU-based flavors define the GPU alias and quantity attached to a virtual machine. One GPU alias can be used for different flavors.
Limitations
- Changing GPU quantity in a flavor affects only new virtual machines. Existing VMs retain their original GPU configuration.
Prerequisites
- GPU-based flavors are created, as described in Creating flavors.
- GPU aliases are created, as described in Managing GPU aliases.
To add a GPU to a flavor
Use the following command:
vinfra service compute flavor set [--gpu <alias:count>] <flavor>
<flavor>- Flavor ID or name
--gpu <alias:count>- GPU configuration in
alias:countformat (e.g.,L40S:2). Can be specified multiple times. The system will automatically determine the GPU type (vGPU or host passthrough) and set the appropriate flavor properties.
For example, to add 2 GPUs with the alias nvidia-319 to the flavor gpu-nvidia-319-2, run:
# vinfra service compute flavor set gpu-nvidia-319-2 --gpu nvidia-319:2
To remove a GPU from a flavor
Use the following command:
vinfra service compute flavor unset --property <property-key> [<property-key> ...] <flavor>
<flavor>- Flavor ID or name
--property <property-key> [<property-key> ...]- Property key to remove from the flavor. Can be specified multiple times.
For example, to remove 2 GPUs with the alias nvidia-319 from the flavor gpu-nvidia-319-2, run:
# vinfra service compute flavor unset gpu-nvidia-319-2 --property "resources:VGPU" "trait:CUSTOM_NVIDIA_319"
