Support for GVT-g vGPUs about intel-device-plugins-for-kubernetes HOT 5 CLOSED

You should be able to experiment with https://github.com/intel/sriov-network-device-plugin where the resourceList is be configured to expose your graphics card to a vfio device.

I've not tried with kubevirt but I'm using a similar mechanism to isolate (QAT) devices to Kata Containers backed pods.

Thanks! I gave it a try, but I'm not entirely sure whether this is to work with virtualized GPUs, or would allow me to pass through an individual (physical) GPU?

I have created two vGPUs, which show up as /dev/vfio/9 and /dev/vfio/10.
When I deploy the daemonset for the sriov-network-device-plugin, only one device is listed.
Creating a pod which uses this device fails: Error: failed to start container "appcntr1": Error response from daemon: linux runtime spec devices: error gathering device information while adding custom device "/dev/vfio/1": no such file or directory.

Here's the configuration file:

{
    "resourceList":
    [
        {
            "resourceName": "gpu",
            "rootDevices": [ "00:02.0" ],
            "sriovMode": false,
            "deviceType": "vfio"
        }
    ]
}

And the output from describe pod:

I1205 13:36:09.720121      15 server.go:85] Allocate() called with &AllocateRequest{ContainerRequests:[&ContainerAllocateRequest{DevicesIDs:[0000:00:02.0],}],}

Let me know if missed something.

@qmfrederik I was thinking about GVT-d so my idea won't work, sorry.

The link to your implementation points to GVT-g wiki.

@mythi Makes sense, thanks.

The link should point to https://github.com/kubedroid/intel-device-plugins-for-kubernetes/blob/vgpu/cmd/vgpu_plugin/vgpu_plugin.go, I've updated the comment.
