9.17.11.5.3. Removing mediated devices from the cluster

Procedure

1. Edit the HyperConverged CR in your default editor by running the following command:

   $ oc edit hyperconverged kubevirt-hyperconverged -n openshift-cnv

2. Remove the device information from the spec.mediatedDevicesConfiguration and spec.permittedHostDevices stanzas of the HyperConverged CR. Removing both entries ensures that you can later create a new mediated device type on the same node. For example:

   apiVersion: hco.kubevirt.io/v1
   kind: HyperConverged
   metadata:
     name: kubevirt-hyperconverged
     namespace: openshift-cnv
   spec:
     mediatedDevicesConfiguration:
       mediatedDeviceTypes:
         - nvidia-231
     permittedHostDevices:
       mediatedDevices:
       - mdevNameSelector: GRID T4-2Q
         resourceName: nvidia.com/GRID_T4-2Q

   • To remove the nvidia-231 device type, delete it from the mediatedDeviceTypes array.
   • To remove the GRID T4-2Q device, delete the mdevNameSelector field and its corresponding resourceName field.
3. Save your changes and exit the editor.
