Using GPUs in VMs
Nodes labelled with
nautilus.io/vfio are configured to passthrough GPUs for kubevirt VMs.
To see the list of such nodes, run
kubectl get nodes -l nautilus.io/vfio=true
You can check the types of exposed GPUs in each node with
kubectl describe node <node-name>,
Capacity section will have a number of
nvidia.com/GA... gpus available.
To use the GPU in VM, add it to the
gpus section of your VM definition with the appropriate type:
