Attaching or Detaching an fGPU

You can attach a flexible GPU (fGPU) to a virtual machine (VM), and detach it at any time.

You can attach fGPUs only to VMs with the highest (1) performance flag. For more information see About Flexible GPUs and VM Types.

To be able to attach an fGPU, you must first allocate it to your account. For more information, see Allocating or Releasing an fGPU.

Linking or Unlinking an fGPU Using Cockpit v2

Linking an fGPU

  1. Click inside the Flexible GPUs dashboard to make checkboxes appear.

  2. Check the box of the fGPU you want to link to a VM.
    The fGPU is selected and an action menu appears.

  3. Click IconLink Link to a VM.
    The LINK TO A VM dialog box appears.

  4. In the VM list, select the VM you want to link the fGPU to.

  5. Click Link.
    The fGPU is scheduled to be linked to the VM.

    To complete the linking of the fGPU, you need to do a stop/start of the VM. A simple restart is not sufficient, as the linking of the fGPU is done when the VM goes through the stopped state.

    For the difference between stop/start and restart, see About VM Lifecycle.

Unlinking a fGPU

  1. Click inside the Flexible GPUs dashboard to make checkboxes appear.

  2. Check the box of the fGPU you want to unlink from a VM.
    The fGPU is selected and an action menu appears.

  3. Click IconUnlink Unlink VM.
    A confirmation dialog box appears.

  4. Click Unlink.
    The fGPU is scheduled to be unlinked from its VM.

    To complete the unlinking of the fGPU, you need to do a stop/start of the VM. A simple restart is not sufficient, as the unlinking of the fGPU is done when the VM goes through the stopped state.

    For the difference between stop/start and restart, see About VM Lifecycle.

Linking or Unlinking an fGPU Using OSC CLI

Linking an fGPU

The LinkFlexibleGpu command attaches one of your allocated flexible GPUs (fGPUs) to one of your virtual machines (VMs).
The fGPU is in the attaching state until the VM is stopped, after which it becomes attached.

You can attach fGPUs only to VMs with the highest (1) performance flag. For more information see About Flexible GPUs and VM Types.

Request sample
$ osc-cli api LinkFlexibleGpu --profile "default" \
    --FlexibleGpuId "fgpu-12345678" \
    --VmId "i-12345678"

This command contains the following attributes that you need to specify:

  • DryRun: (optional) If true, checks whether you have the required permissions to perform the action.

  • FlexibleGpuId: The ID of the fGPU you want to attach.

  • VmId: The ID of the VM you want to attach the fGPU to.

The LinkFlexibleGpu command returns the following elements:

  • ResponseContext: Information about the context of the response.

Result sample
{
  "ResponseContext": {
    "RequestId": "0475ca1e-d0c5-441d-712a-da55a4175157"
  }
}

Unlinking an fGPU

The UnlinkFlexibleGpu command detaches a flexible GPU (fGPU) from a virtual machine (VM).
The fGPU is in the detaching state until the VM is stopped, after which it becomes available for allocation again.

Request sample
$ osc-cli api UnlinkFlexibleGpu --profile "default" \
    --FlexibleGpuId "fgpu-12345678"

This command contains the following attributes that you need to specify:

  • DryRun: (optional) If true, checks whether you have the required permissions to perform the action.

  • FlexibleGpuId: The ID of the fGPU you want to detach from your VM.

The UnlinkFlexibleGpu command returns the following elements:

  • ResponseContext: Information about the context of the response.

Result sample
{
  "ResponseContext": {
    "RequestId": "0475ca1e-d0c5-441d-712a-da55a4175157"
  }
}
